- ※4）Rapid Response：
Mini oral session (shorter than oral presentation)
- 01）(Heart) Techno-Academy: Mitral
This session in a lecture format will involve the participation of the main faculty of the AATS Mitral Conclave, including David Adams, Gilles Dreyfus, Joseph Woo, Khalil Fatouch, Taweesak Chotivatanapong, and other doctors , and domestic experts. In this session, the controversial issues still remaining concerning the theory and techniques of mitral valvuloplasty will be discussed by overseas and domestic experts through Japanese and English two-way simultaneous interpretation. Discussions include such perspectives as whether to conserve or resect a prolapsing valve leaflet, what measures should be taken regarding SAM and ring selection, how to re-form a valve in patients with MR relapse, to what extent valve formation can be performed for rheumatic MR, whether patch formation is effective for active IE with severe valve destruction, and how subvalvular and leaflet interventions should be performed in valvuloplasty for functional MR. The purpose of the session is to provide an opportunity whereby the participants share knowledge, understand the concept of mitral valvuloplasty for varied etiologies, and learn various theoretically-supported techniques.
- 02）(Heart) Techno-Academy: Aortic Valve Repair
Aortic valve repair has made remarkable progress with improving outcomes, however, it has not become widespread. When considering aortic valve repair, earlier intervention may result in more durable repair. However, the current guidelines for surgical intervention of aortic regurgitation were developed by assuming replacement. To modify the guidelines, superior long-term outcomes after repair in a large cohort are essential.
In this session, the basic concept and procedures will be reconfirmed among the audience at first. Prof. Schäfers, a world-leading surgeon, will play a key role. Then the other speakers will raise associated considerations, which will be resolved by all participants. The main purpose of this session is to deepen understanding of this surgery through discussion.
- 03）(Heart) Techno-Academy: Coronary
Techno-Academy: Coronary is preparing a session that will enable participants to understand the new standard of surgery for ischemic heart disease. The speakers will be expected to present the surgical theory and details of the operation using a video presentation. The focus of the theme is technique, but not just technique. Scientific approaches and the academic background will also be concurrently presented. The session will involve discussions with domestic and overseas invited speakers to deepen the participants’ knowledge and explore the direction of surgery for ischemic heart disease in the future. The session is scheduled to last 2.5 hours. Japanese and English two-way simultaneous interpretation will be available.
- 04）(Heart) Techno-Academy: Heart Failure
Treatments for angina and valvular disease have become widely used, significantly improving the vital prognosis of patients. However, severe myocardial damage due to myocardial infarction and valvular disease, as well as diseases causing direct damage to the myocardium such as cardiomyopathy and myocarditis, is a major factor that determines the prognosis of patients. This is a major challenge that must be continuously addressed in the field of cardiac surgery. In this session, the participants are expected to learn surgical techniques for heart failure, with a focus on mechanical circulatory support (MCS), use of which has rapidly increased in recent years, as well as those for left ventriculoplasty and heart implantation, which fall into the category of conventional surgery. Although the session is intended for surgeons who are mainly engaged in MCS, others who are infrequently involved with MCS in daily practice are also expected to attend the lecture to know how to treat occasionally encountered cases of severe heart failure and to deepen their understanding of MCS and appropriately use it in heart failure surgery.
- 05）(Heart) Techno-Academy: Aorta
Due to the emergence of stent grafts, the therapeutic strategy for aortic arch disease is gradually shifting from open surgery to minimally invasive surgery. However, from the viewpoint of avoiding cerebral complications, which is the biggest concern in aortic arch disease, and postoperative aorta-related complications, all available surgical procedures still involve problems to be solved. Various surgical procedures have been proposed to solve the problems, and much controversy remains in the field of aortic arch surgery. In this session, the participants are expected not to discuss the relative merits and demerits of surgical procedures but to learn almost all of the current surgical techniques for aortic arch disease from respective experts, and to use the session as an opportunity to consider ways to solve the problems facing each institution.
- 06）(Heart) Techno-Academy: Minimally Invasive
In this session, overseas speakers and domestic experts will give lectures on the leading-edge techniques for MICS and robotic cardiac surgery, which are drawing increasing attention because these procedures will be included in the scope of insurance coverage when the medical fees are revised in 2018, including MICS Maze. In addition, the future direction of minimally invasive cardiac surgery will be explored from such perspectives as the present situation and evidence of MICS in Europe and the US, differences associated with endoscopic systems (4K high-resolution 2D or 3D microscopy), tips and pitfalls of total endoscopic MICS, MVP of complex lesions, to what extent the incision size can be reduced, and how to use MICS and robotic surgery differentially, including the present situation and future prospects of transcatheter MVR.
Furthermore, two overseas experts will give lectures on two sutureless valves that are expected to be granted regulatory approval, to deepen understanding of the features, techniques, and indications of the newly introduced sutureless valves from such perspectives as the indications for use of a sutureless valve, differential usage of conventional AVR and TAVR, features of the two valves and procedural differences between them, and differences in clinical results of pacemaker implants, etc.
- 07）(Heart) Techno-Academy:Congenital-1 Repair of atrioventricular septal defect
Repair of an atrioventricular septal defect consists of closing the defect and dividing the common atrioventricular valve into two separate valves. In this procedure, valve function must be properly maintained or made better than before. Because of the diverse morphological appearances of defects and/or the atrioventricular valve, there are still many technical tips to avoid pitfalls. Through a detailed discussion of the technical aspects, attendees will be exposed to emerging techniques and technical nuances for improved and reproducible surgical repair of atrioventricular septal defects.
- 08）(Heart) Techno-Academy: Congenital-2 Techniques for repair of aortic arch in congenital heart disease
The outcomes of aortic arch repair of congenital aortic arch lesions typified by aortic coarctation have improved since the first report on the repair of coarctation in 1945. However, at present, the approaches to aortic repair are devised by each pediatric cardiac surgeon to prevent complications. In this session, the operating surgeons will explain detailed techniques of aortic repair (excluding Norwood, DKS) in an easy-to-understand manner based on results. We hope that this session will lead to further improvements of this technique in the future.
- 09）(Heart) Techno-Academy: Congenital-3 Knacks & Pitfalls: Surgery for Total Anomalous Pulmonary Venous Return
Neonates with Total Anomalous Pulmonary Venous Return (TAPVR) have been rescued since around 40 years ago. However, re-stenosis of the repaired PVs had been very difficult to manage before 2000. Even with the sutureless repair technique, it is not easy to achieve a mortality rate of less than 5% and a re-stenosis rate of less than 20%.
In this Techno-Academy, we will have a keynote and other lectures from several experts in the field of TAPVR repair. All experts will discuss both technical considerations and knacks & pitfalls. Please join the session to gain detailed information on TAPVR repair.
- 10）(Lung) Techno-Academy: Thoracic-1 Minimal invasive and robot-assisted thoracic surgery
Recent advances in minimal invasive thoracic surgery include video-assisted thoracic surgery (VATS), uniport VATS, and robot-assisted thoracic surgery (RATS). Speakers are requested to present surgical approaches, indications, and procedures performed in their institutes, to explain the advantages and points of note based on the presented data, and to discuss the standardization, future prospects, and technical transfer to the next generation.
- 11）(Lung) Techno-Academy: Thoracic-2 Tracheobronchial reconstruction
Tracheobronchoplasty is used as a reconstructive technique in airway surgery; benign airway disease, bronchial anastomosis in lung transplantation, and malignant diseases extending central airway. Speakers are requested as an expert to present techniques in bronchial anastomosis with discrepant diameters, reducing longitudinal tension of anastomosis, and pitfalls in airway reconstruction especially after chemoradiation treatment.
- 12）(Esophagus) Techno-Academy: Esophagus
In the operation for thoracic esophageal carcinoma, the quality of the recurrent nerve lymph node dissection directly determines the clinical results, especially the postoperative recurrence rate, because lymph node metastasis is frequent in this area. On the other hand, aggressive lymphadenectomy around the recurrent nerve may lead to severe postoperative recurrent nerve paralysis. Especially, because the left recurrent nerve is longer and is located at the deepest area when viewed from the right thoracic cavity, left recurrent nerve lymph node dissection is the most important surgical technique and is considered the surgical procedure that reflects the ability of each institution.
In this session, expert esophageal surgeons in the fields of open thoracotomy, thoracoscopic surgery in the lateral decubitus position, thoracoscopic surgery in the prone position, mediastinoscopic approach and robotic surgery will give highly detailed lectures focusing on the left recurrent nerve lymph node dissection; they will describe methods of creating the surgical field, surgical devices to use, and the surgical logic for lymphadenectomy.
- 01）(Heart) Reconsideration of mitral valve repair technique from long-term outcomes
Mitral valvuloplasty is now commonly used and produces almost satisfactory results in terms of vital prognosis and avoidance of repeat surgery. However, MR relapse in the late phase is observed in some cases, and so this surgical procedure still needs to be improved.
To improve the quality of valvuloplasty, various modifications will need to be made. Issues include differences in basic techniques for valvuloplasty such as resection and stitching of the valve leaflet and artificial tendon reconstruction; modifications to the basic techniques and adjunctive techniques and their indications; surgical approach (MICS/median incision); selection of the artificial valve ring; and prognosis of the pericardial patch. The mechanism of MR relapse and the optimal procedure for repeat surgery are also points to consider. In this session, long-term outcomes of mitral valvuloplasty will be analyzed to reconsider the future direction of high-end mitral valvuloplasty.
- 02）(Heart) How should we maximally utilize bilateral internal thoracic arteries?
The use of bilateral internal thoracic artery (ITA) in coronary artery bypass grafting (CABG) has been encouraged for many years based on many observational studies. However, the ART trial, a prospective randomized multicenter trial, showed no difference in the five-year mortality, myocardial infarction incidence, and stroke incidence between CABG with bilateral ITA and single ITA, triggering many discussions. This symposium focuses on the use of bilateral ITA for better long-term results and calls for abstracts concentrating on graft design, types of other simultaneously used grafts, patient selection, evaluation of coronary artery lesions, and postoperative medical therapy.
- 03）(Heart) Mechanical circulatory support for acute heart failure – exploring the best strategy –
Although acute cardiogenic shock, such as acute myocardial infarction, fulminant myocarditis, and acute worsening of chronic heart failure, is often experienced, the treatment results remain unsatisfactory. There are now many choices for mechanical circulatory support. Therefore, speakers are asked to discuss which treatment strategy is the best at each institution for this difficult pathology to improve the treatment results.
- 04）(Heart) The best surgical strategy for acute type A aortic dissection: still replacement of the ascending aorta, or extended ascending and arch replacement? – A re-consideration based on long-term results and the results of additional surgery after the first surgery
For acute type A aortic dissection, replacement of the ascending aorta is the minimum required procedure to save lives, but there remain some problems with the residual dissected aorta which might need additional surgical treatment such as dissection of thoracic and abdominal aortic aneurysms. To decrease the incidence of dissection of aortic aneurysms and the risk of additional surgical treatment, extended surgery, such as simultaneous arch replacement with or without the frozen elephant trunk procedure or replacement of the ascending aorta and partial arch replacement with reconstruction of the brachiocephalic artery, is becoming more popular. However, the acute results of extended surgery might be worse than replacement of the ascending aorta; not all patients with replacement of the ascending aorta require additional surgery; and the risk of the additional surgery is becoming lower with stent grafts. Accordingly, replacement of the ascending aorta might still be reasonable. Therefore, speakers are asked to discuss which procedure is better, replacement of the ascending aorta or extended surgery, based on the acute and mid- and long-term surgical results including some additional procedures.
- 05）(Lung) Extended resection for Pancoast tumor and/or vertebra-invading lung cancer
Pancoast tumor and vertebra-invading lung cancer have been challenging for thoracic surgeons. Speakers are requested to present treatment strategy, indications and surgical approaches for these lung cancers, and to discuss therapeutic outcomes in their institutes.
- 06）(Lung) Lung cancer surgery after chemoradiation therapy
Induction chemoradiotherapy is applied for locally advanced lung cancer (e.g. cN2, cN1, cT4) to achieve a complete resection or to prolong survivals. Salvage surgery is applied for residual or recurrent malignant tumors after definitive chemoradiotherapy. Speakers are encouraged to present their surgical outcomes after chemoradiation therapy with a clear description of the subjects and indication of the study.
- 07）(Esophagus) The current status and future vision of the esophageal carcinoma surgery from the view of the approach to the mediastinum
Recently in the esophageal carcinoma surgery, in addition to the open thoracotomy, various endoscopic surgery such as thoracoscopic surgery in the lateral decubitus position, thoracoscopic surgery in the prone position, mediastinoscopic approach and robotic surgery, are induced and the adaptation has also expanded to advanced cancer and salvage surgery.
In this session, we wish to focus on the merit and demerit of each surgical procedure and discuss regarding the plan to induce each merit to another surgical procedure and/or the plan to be induced from another surgical procedure to overcome the weakness. Finally, such future view that leads to improve the clinical result for the esophageal carcinoma surgery is expected to draw.
- 01）(Heart) How should we treat functional tricuspid regurgitation? : Surgical strategy according to TR grade
Functional TR results most commonly from left-sided valvular disease. FTR is classified into a wide range from mild TR due to simple annular dilatation to severe TR due to leaflet tethering. The purpose of this session is to discuss surgical strategies for FTR, such as prophylactic annuloplasty, ring selection, valvular or sub-valvular procedure, or valve replacement, according to the severity of FTR.
- 02）(Heart) Pursuit of quality and safety in MICS
MICS has become the standard approach to mitral valve surgery in many centers. The rapid spread of MICS is supported by good results comparable to the sternotomy approach and tips for safety. Is the result of mitral valve surgery with MICS equal to the conventional approach? What are the important tips and monitoring systems to maintain the safety of MICS which requires the establishment of a cardiopulmonary bypass using peripheral vessels and restricted setting with long-shafted instruments in a limited working space? The purpose of this session is to standardize the latest MICS system in last days in the Heisei era in the last JATS meeting in the era.
- 03）(Heart) Saphenous vein graft revisited
Although long-term patency of the saphenous vein graft on coronary artery bypass grafting is considered inferior to that of arterial grafts, the saphenous vein is still the most harvested and used graft. Also in a randomized trial, five-year clinical results of coronary artery bypass surgery using bilateral internal thoracic artery were not excellent. In this session, we will discuss how to improve long-term outcomes with vein grafts and call for abstracts focusing on topics such as vein graft harvesting, preservation method after harvest, anastomosis site, modification of surgery, and postoperative medical therapy.
- 04）(Heart) Pursuing the best long-term management for implantable ventricular assist devices
At present, implantable ventricular assist devices (iVADs) can only be used as a bridge device for transplantation in Japan, but the waiting time for heart transplantation is longer than 5 years. Moreover, destination therapy for severe heart failure will start in the near future. Therefore, the necessity of long-term circulatory support with VADs is increasing. As is known, infection, stroke, and recurrent heart failure due to valve incompetence are major unpreventable complications of long-term iVAD support, but it may be possible to decrease the incidence of these complications and re-hospitalization with intra-operative and postoperative management. Speakers are asked to discuss the countermeasures of each institution to prevent major complications and improve the results of long-term iVAD support.
- 05）(Heart) Surgical strategy for extended thoracic aortic disease ( from the ascending aorta (Zone 0) to thoracic descending aorta which needs reconstruction of three arch vessels)
After stent grafts became commercially available, various surgical procedures appeared for extended thoracic aortic disease including all three arch vessels, such as arch replacement with frozen elephant trunk, a hybrid procedure with debranching of the arch vessels, and total endovascular repair. However, each procedure has its own problems: high stroke rate and stent graft-related aortic complications. Therefore, speakers are asked to discuss surgical strategies for patients with extended thoracic aortic disease including all three arch vessels.
- 06）(Heart) Feedback from the long-term results for the ideal Jatene procedure (arterial switch operation)
The Jatene procedure has a long history of over 40 years since the first successful report, and has become a common surgical procedure performed in many institutes in Japan. A variety of changes in the surgical strategy (primary, secondary after PAB, etc.) and technique (pulmonary reconstruction, coronary anastomosis, etc.) have been made. Discussions on the link between these operative factors and the long-term complications (PS, AR, coronary obstruction, airway obstruction, etc.) will be held to generate feedback for the ideal Jatene procedure.
- 07）(Lung) Multimodality treatment for malignant pleural mesothelioma
Curative surgical procedures for malignant pleural mesothelioma include extrapleural pneumonectomy (EPP), and pleurectomy and decortication (P/D). It is essential to treat this malignancy with surgery plus other modalities. Speakers are encouraged to present therapeutic outcomes with a focus on multimodality treatment rather than surgery alone.
- 08）(Lung) Troubleshooting in thoracic surgery
Surgery sometimes accompanies unforeseeable events or problems. Speakers are requested to make video presentation of intraoperative troubles (bleeding, airway injury, etc) or postoperative complications, to discuss the resolution and subsequent improvement, and eventually to allow the audience to share the experience.
- 09）(Esophagus) The best reconstruction method after esophageactomy for thoracic esophageal carcinoma
The best reconstruction method after esophagectomy for thoracic esophageal carcinoma is the method, that is the anastomotic leakage is rare as the short-term morbidity, and solid food can pass though the anastomotic site smoothly without aspiration and reflux and sufficient oral intake can be achieved as the long-term results. In this session, we wish to be discussed in terms of the ideal reconstruction method in the short- and long-term view of the clinical results, especially focusing on the selection of the reconstruction organ and the reconstruction route and the way to build up the reconstruction organ and to perform anastomosis. Moreover, the evaluation method of the blood flow profile in the reconstructed organ is expected to discuss.
- 01）(Heart) Valvular Heart Disease
Although surgery for valvular disease has made great progress, it still involves many problems yet to be solved. Surgeons may have encountered difficult cases while on the learning curve, and some of the cases may have resulted in an unfavorable outcome. The purpose of this session is to share such valuable experiences among all participants and to raise the technical and knowledge levels of the participants for the future by listening to the opinions of experts.
- ● Valvular disease in general
Cases with difficulty in performing mitral valvuloplasty, re-do cases, infectious endocarditis, etc.
- ● Aortic valvuloplasty
Cases with difficulty in determining the indication (e.g., decreased left ventricular function, old age, acute dissection), type Id lesions including infectious endocarditis, type III lesions, imperfectly fused bicuspid valve, quadricuspid valve, asymmetric valve leaflet shape, etc.
- ● MICS
Complications, conversion cases, etc.
- ● Valvular disease in general
- 02）(Heart) Coronary
With the advance in surgical treatment for coronary artery disease, the treatment results are generally stabilizing. However, we still occasionally experience difficult-to-treat cases. The purpose of this session is to share such valuable experiences among participants and have the audience actively join the discussion based on the opinions of experts, to contribute to the development of surgical treatment. We welcome a variety of surgical treatment methods in the field of coronary artery disease, including difficult-to-treat cases, bailout cases, and nightmare cases.
- 03）(Heart) Aorta
・Cases of surgery for stent graft-related complications, associated with the widespread use of stent grafts
・Cases in whom great effort was required in the subsequent open surgery due to an implanted stent graft
・Cases in whom new modifications were made to thoracoabdominal aortic surgery (open surgery)
・Cases in whom new modifications were made to hybrid surgery such as debranching TEVAR or minimally invasive treatment such as complete endovascular treatment
・Cases in whom additional attempts were made for surgical treatment for chronic type B aortic dissection
・Cases in whom surgical treatment for infectious aortic disease (including artificial blood vessel infection) was difficult or modifications were made to the treatment
The participants are expected to present modifications made to the above difficult-to-treat cases to improve the treatment results in a case conference format for future utilization in medical practice.
- 04）(Heart) Heart Failure
・VAD implantation for congenital heart disease, small-body patients (including children), and other complicated clinical conditions
・Treatment for complications after VAD implantation, such as infection after VAD implantation and new-onset AR
・Techniques that are considered particularly important in routine VAD-related surgery, such as bridge-to-bridge surgery, positioning of inflow cannula for placement of implantable VAD, method for RVAD placement in BiVAD implantation
The participants are expected to present cases using the above surgical techniques and to discuss their respective actions taken from diverse standpoints for future utilization in medical practice.
- 05）(Heart) Congenital
Surgical treatment of congenital heart disease has steadily advanced, and outcomes have been improved. But surgeons sometimes experience complex or challenging cases. The purpose of this session is to share such significant experiences among participants and to connect them to the future development of surgical treatment. The seats will be placed in a circular arrangement, and the speakers are expected to present at the center of the venue. Screen monitors will be positioned around the site. The session will encourage lively discussions between the speakers and the participants. The session calls for a wide range of abstracts from child cases to adult cases, bailout cases, nightmare cases or cases where it was difficult to determine the treatment strategy.
In this session, the speakers will be asked to present cases requiring discussion on (1) therapeutic strategy including preoperative treatment, (2) selection of surgical procedures including approach, (3) treatments for postoperative complications, and (4) therapeutic outcomes. Wide-ranging discussion would be promoted on the basis of case conference.
- 07）(Esophagus) Multimodal treatment for the locally advanced esophageal carcinoma
Regarding the treatment for so-called “T4bM0” locally advanced esophageal squamous cell carcinoma, multimodal treatment using mainly definitive chemoradiotherapy is the norm. However, especially for patients with esophageal fistula and/or severe stenosis, the therapeutic strategy is different in each institute and various therapeutic techniques using all the abilities of each institute are required.
In this session, we will present some patients with T4bM0 esophageal squamous cell carcinoma who were treated using multimodal treatment and discuss the therapeutic concept, therapeutic methods and clinical results.
- 08）(Esophagus) Multimodal treatment for the esophageal carcinoma with multiple primary carcinoma
From the concept of field cancerization, the esophageal carcinoma patient is often suffering also from multiple primary carcinomas such as simultaneous and/or metachronous head and neck carcinoma. In the treatment for such patients, some special therapeutic strategy is required especially in terms of the surgical procedure, radiation field and chemotherapeutic regimen, and which carcinoma to treat first must also be considered.
In this session, we will present some esophageal carcinoma patients who could not be treated according to the standard therapeutic strategy because of multiple primary carcinomas and required a thoughtful therapeutic strategy, and will actively discuss the therapeutic concepts.
