In this session, experts in MICS CABG will report on their clinical results and present their position, future prospects, and the future spread of MICS CABG.
Call for Panel Discussion	Field MICS-Valve-Robot Theme Indications and limitations of minimally invasive/robotic heart valve surgery Date November 4, 8:00-9:30, Room 2, 2F, Ishikawa Ongakudo Outline This panel discussion aims to explore the indications and limitations of minimally invasive cardiac surgery (MICS) and robotic approaches in heart valve surgery. Expert clinicians will discuss appropriate patient selection, surgical techniques, and outcomes based on their clinical experiences and evidence, focusing on challenging scenarios such as redo cases, low ventricular function cases, and cases with respiratory dysfunction, where MICS and robotic surgery are generally considered challenging.
Call for Workshop	Field MICS-Valve-Robot Theme The role of patient-site-surgeon Date November 2, 8:00-9:30, Room 1, 2F, Ishikawa Ongakudo Outline Robotic-assisted cardiac surgery is a team effort, and the patient-site-surgeon is at the center of the team. However, there has not been sufficient discussion on the importance of the patient-site-surgeon and what role he/she should play. The role of the patient-site-surgeon in each institution and the future prospects for the robotic cardiac surgery will be discussed.
Call for Symposium	Field TEVAR Theme Medium-term results after Frozen elephant trunk (FET) arch replacement for acute type A dissection - is there an improvement in prognosis? Date November 2, 8:00-9:30, Room 5, 3F, Hotel Nikko Kanazawa Outline The J-ORCHESTRA study reported early good results of Frozen Elephant Trunk arch replacement. For acute type A aortic dissection, now the standard procedure, did this approach change the fate of the distal aorta, improve prognosis? We would like to discuss the medium-term results of this surgery compared to conventional non-elephant noses and conventional elephant noses.
Call for Workshop	Field TEVAR Theme The pros and cons of Zone 0 TEVAR - the distinction from graft replacement Date November 2, 9:40-11:10, Room 5, 3F, Hotel Nikko Kanazawa Outline Zone 0 TEVAR has been performed, including Najuta, physician-modified device, and in-situ fenestration. On the other hand, the results of arch replacement in Japan are generally good. Are there any benefits to performing this procedure? In what cases are these acceptable? At this point in time when new corporate devices are scheduled to launch in the near future, please discuss how they use.
Call for Symposium	Field TEVAR Theme The pros and cons of TAAA - the distinction from graft replacement . Date November 3, 8:00-9:30, Room 2, 2F, Ishikawa Ongakudo Outline Because of the most invasive procedure, the prognosis of thoracoabdominal aortic aneurysms is influenced more strongly by systemic conditions than by local anatomy. This is even more pronounced in the case of atherosclerotic aneurysms. Therefore, it is important to understand the physical condition including life expectancy. So what are high-risk cases for TAAA, and how are cases that should be abandoned for laparotomy treated? Please discuss based on the data of your own facility.
Call for Workshop	Field Ischemic heart disease Theme CABG's challenge for left ventricular dysfunction Date November 4, 9:45-11:15, Room 8, 4F, Hotel Nikko Kanazawa Outline In this workshop, we would like to verify and deepen the discussion on the effect of isolated coronary artery bypass surgery on left ventricular dysfunction (less than or equal to LVEF 30%). While approaches to left ventricular dysfunction are diversifying (IABP, on-pump beating, ECMO, and Impella), clarifying the safety and effectiveness of CABG in improving cardiac function is expected to be one of the advantages over PCI. We would like the discussants to provide answers to clinical questions such as whether cardiac function is actually improving, what kind of revascularization is safe and effective, and whether long-term heart failure can be prevented.
Call for Workshop	Field Research basic extracorporeal circulation Theme The up-to-dates on strategies of hemostasis in cardiovascular surgery Date November 2, 15:00-16:00, Room 7, 4F, Hotel Nikko Kanazawa Outline Perioperative coagulopathy in cardiovascular surgery is associated with multiple factors, and the various challenges have been carried out for the better hemostasis. We would like to have reports and the discussion on the latest hemostasis strategies, including blood transfusion algorithms incorporating blood viscoelasticity tests and methods of using hemostatic devices.
Call for Workshop	Field Research basic extracorporeal circulation Theme Myocardial protection for MICS: Theory and practice for safety Date November 4, 9:40-11:10, Room 5, 3F, Hotel Nikko Kanazawa Outline Although MICS approaches have several weak points (i.e., narrow view of the operation field, difficulties of touch examination or manipulation, and positioning limit of the instruments), they must secure comparable quality of safety for myocardial protection to median sternotomy approaches. The important maneuvers for safety during surgery include (1) early detection of the insufficient infusion of cardioplegia, (2) avoidance of air/debris delivery into the coronary circulation during cardioplegic re-infusions or water tests for mitral valve competency, and (3) poor temperature management in case that the aortic cross-clamp time is prolonged. The theory and practice of myocardial protection for safety in MICS will be discussed.
Call for Workshop	Field Severe heart failure, VAD, transplantation Theme Destination therapy in Japan: Real world practice Date November 3, 8:00-9:30 Room 7, 4F, Hotel Nikko Kanazawa Outline Almost 3 years elapsed since the reimbursement of destination therapy. Desemmination of DT seems to be less active than expected even in consideration of negative impact of COVID-19 pandemic. There are not a few old patients in advanced heart failure. A good news is that DT certified hospitals increased up to 19 in July, 2023. Interative discussions are mandatory to find out proper starategies to promote DT in Japan from the medical, social, and ethical aspects.
Call for Panel Discussion	Field Severe heart failure, VAD, transplantation Theme Surgical strategy for MCS in cardiogenic shock Date November 2, 9:40-11:10, Room 1, 2F, Ishikawa Ongakudo Outline Post-cardiotomy cardiogenic shock (PCS) is one of important issues surgeons have to overcome. In this symposium we discuss surgical strategy for PCS using mechanical circulatory support (MCS) and try to answer to important clinical questions including ①central cannulation or peripheral cannulation? ②pre-operative support or post-operative support? ③Impact of MCS on coagulopathy after cardiac surgery ④Escalation of MCS for longer support. I hope that this symposium will shed light on the benefit of MCS in the treatment of post-cardiotomy cardiogenic shock.
Call for Symposium	Field Severe heart failure, VAD, transplantation Theme Challenge to the limits of non-device surgical treatment for severe heart failure Date November 4, 15:20-16:20, Room 5, 3F, Hotel Nikko Kanazawa Outline Heart transplantation and ventricular assist device are the first-line treatment for end-stage heart failure. However, restrictive indication and cost limit their indications. In contrast, there are several surgical treatment options for stage C or less heart failure to prevent its progression. In this session, the challenge and current status of non-device treatment, such as left ventriculoplasty, regenerative therapy, and functional MR treatment, will be discussed.
Call for Panel Discussion	Field Aorta Theme A Comprehensive Treatment Strategy for Hereditary Aortic Disease Date November 4, 9:40-11:10, Room 9, 4F, Hotel Nikko Kanazawa Outline Hereditary aortic diseases have several features; vascular fragility, extensive aortic lesions, concurrent valvular heart disease, early onset (resulting in need for long-term follow-up), etc. and require treatment strategies different from those for general aortic disease. Therefore, we would like you to present a comprehensive treatment strategy for hereditary aortic diseases based on the treatment experience at each facility.
Call for Symposium	Field Aorta Theme Surgical treatment for infectious aortic disease Date November 2, 13:50-15:50, Room 1, 2F, Ishikawa Ongakudo Outline Infectious aortic disease includes primary infectious aortic aneurysm and secondary infection after aortic replacement/stent graft implantation, and may be complicated by aortobronchial fistula or aortoesophageal fistula. There is room for improvement in these treatment results. Thus, we expect to deepen discussions on treatment strategies such as surgical technique, timing of surgery, and use of antibiotics, based on the experience of each facility, to improve treatment results.
Call for Panel Discussion	Field Arrhythmia Theme Current and future of left atrial management for AF Date November 4, 14:15-15:15, Room 5, 3F, Hotel Nikko Kanazawa Outline The development of the left atrial appendage closure devices has ushered in the era of easy surgical or catheter-based the left atrial appendage closure. However, there are still many questions regarding the significance and methods of the left atrial appendage closure. Can the left atrial appendage closure prevent thrombus formation in the left atrial appendage? What is the preferred method of the left atrial appendage closure? What is the significance and indications for closure of the left atrial appendage alone without rhythm control? In this panel discussion, we will evaluate the current status of surgical or catheter-based the left atrial appendage closure and the significance of the left atrial appendage closure, and discuss the future prospects.
Call for Symposium	Field Valvular heart disease Theme Aortic stenosis - Selection of prosthetic valve and operative procedure considering lifetime management Date November 4, 9:40-11:10, Room 6, 3F, Hotel Nikko Kanazawa Outline In the era of 100 years of life expectancy, lifetime management of aortic stenosis is gaining more focus. Aortic annulus enlargement and insertion of a larger valve to enable subsequent TAVI is one of those oprtions. In this session, we will discuss the procedural safety, durability, performance, and future options for different lifetime management strategy.
Call for Panel Discussion	Field Valvular heart disease Theme Feedback of failure modes of aortic valve repair from reoperative findings Date November 3, 15:30-16:30, Room 8, 4F, Hotel Nikko Kanazawa Outline Long-term durability after aortic valve repair depends not only on selection of appropriate procedures for appropriate patients, but also on avoidance of inadequate repair techniques. This session is designed to determine failure modes and pathophysiological problems at the initial surgery from reoperative findings and to discuss the ideal strategy of aortic valve repair.
Call for Workshop	Field Valvular heart disease Theme Left atrial volume reduction surgery; Verification of procedure and effectiveness Date November 2, 13:50-14:50, Room 7, 4F, Hotel Nikko Kanazawa Outline Severely enlarged left atrrium is associated with mitral valve dysfunction, irreversibility of atrial fibrillation and respiratory failure. Reappraisal of left atrial volume reduction surgery is thus under way. However, adequate indication and techniques are still unclear. Clinical outcomes of various volume reduction procedures will be discussed to determin appropriate indication and safe and effective techniques.
Call for Panel Discussion	Field Valvular heart disease Theme Surgical management of very severe tricuspid regurgitation with right ventricular dysfunction Date November 4, 8:00-9:30, Room 6, 3F, Hotel Nikko Kanazawa Outline For very severe tricuspid regurgitation associated with significant leaflet tethering, tricuspid valve annuloplasty alone has the high risk of recurrent regurgitation. As treatment options are expanding to include various additional repair techniques, valve replacement, and catheter-based valve repair, we would like to discuss what is required to improve patient prognosis. Long-term results evaluated by various modalities and restoration of right heart function will be focused.
Call for Symposium	Field Congenital Theme Heart valve surgery in children Date November 2, 9:40-11:10, Room 3, 3F, ANA Crowne Plaza Hotel Outline The surgery of valvular disease in children is one of the most challenging areas due to the variety of diseases and morphologies, valve size, and growth of the involved pediatric patients. We would like to discuss the latest experience of each institution in this area of surgical treatment.
Call for Workshop	Field Congenital Theme Reconstruction of central pulmonary artery Date November 2, 13:50-14:50, Room 3, 3F, ANA Crowne Plaza Hotel Outline We sometimes encounter the difficult cases such as hypoplasia, coarctation and interruption of the central pulmonary artery. Various surgical procedures have been reported to create a well-formed central pulmonary artery. In recent years, it has become necessary to deal with cases in which PDA stents are placed, and such cases may require more complicated procedures. We would like to bring together the experiences of each facility in this area and deepen the discussion.
Call for Workshop	Field Congenital Theme Management for blind-end ventricle Date November 4, 15:20-16:20, Room 6, 3F, Hotel Nikko Kanazawa Outline Occasionally, patients with PA-IVS, HLHS, and severe Ebstein, etc. after Fontan operation develop unanticipated complications of blind-end ventricles. Until now, there has been almost no discussion focusing on the hypoplastic and blind-end ventricle. The aim of this workshop is to share the surgical experiences from different institutions, and to make a contribution towards the future decision-making process concerning surgical strategy.

Thoracic Surgery

Call for Symposium	Field Surgical techniques_Minimally invasive_Expansion_New technology Theme Approaches to diagnosis and treatment using novel technologies for small sized lung cancer Date November 3, 8:00-9:30, Room 3, 3F, ANA Crowne Plaza Hotel Outline Although the number of peripheral small-sized lung cancers is increasing, various measures are required for preoperative diagnosis, intraoperative tumor identification, and securing resection margins. On this circumstances, novel diagnostic and therapeutic approaches including robotics-technologies have also been reported. In this session, we would like to discuss the current status and potential of these technologies for small-sized lung cancer.
Call for Panel Discussion	Field Surgical techniques_minimally invasive_expansion_new technology Theme Minimally invasive surgery for extended resection after non-surgical treatment Date November 4, 9:45-11:15, Room 3, 3F, ANA Crowne Plaza Hotel Outline With recent advances in non-surgical therapy, salvage surgery is increasing. It usually requires pneumonectomy, bronchoplasty, pulmonary angioplasty, etc., and sometimes requires cross clamping of the pulmonary artery, and is highly invasive for such complicated surgery. Please discuss how minimally invasive approaches can be applied in this area. It would be interesting if we could make a comparison with the conventional open-chest salvage.
Call for Workshop	Field Surgical techniques_minimally invasive_expansion_new technology Theme Completion lobectomy after segmentectomy Date November 4, 15:20-16:20, Room 3, 3F, ANA Crowne Plaza Hotel Outline Completion lobectomy for local recurrence after segmentectmy is a promising sugical option for recurrence. However, it is the most difficult and safety-conscious procedure for thoracic surgeons, and its indication as well as surgical strategy should be thoroughly considered preoperatively. We would like to discuss about the knacks and pitfalls of completion lobectomy, its outcomes, and, how should the initial lobectomy be performed to avoid completion segmentectomy as much as possible.
Call for Video Workshop	Field Non-tumor Theme Surgical challenges with intractable pulmonary infections Date November 4, 14:15-15:15, Room 4, 3F, ANA Crowne Plaza Hotel Outline The history of chest surgery is one of battling against pulmonary infections. For some patients with pulmonary mycobacteriosis, mycosis, lung abscesses, or other similar conditions, surgery is the only treatment option. These patients have a poor general condition due to underlying disease or malnutrition, with pulmonary lesions firmly adhering to the pleura and perivascular tissue, making the surgery highly difficult. Furthermore, since complications—including thoracic empyema due to prolonged air leakage, bronchopleural fistula, and pathogen spread during the operation—frequently occur, intra- and post-operative preventative measures affect patient prognosis. In this session, the presenters will show videos from challenging surgeries on intractable pulmonary infections, and the issues for discussion will include preoperative treatment, surgical innovations, and measures for preventing complications during and after surgery.
Call for Panel Discussion	Field Transplantation Theme Is it possible to standardize periopperative management of lung transplantation? Date November 2, 8:00-9:30, Room 8, 4F, Hotel Nikko Kanazawa Outline The number of lung transplants in Japan has been steadily increasing, and perioperative results have been stabilized. Although the management of transplant patients has been diligently devised by each institutes, standardization will be necessary for the further development of lung transplantation in Japan, and it will be fundamental to create evidence through joint research in the future. In this session, each speaker will introduce the content that can be shared by the management method of each institute and discuss which can be standardized.
Call for Workshop	Field Mediastinum Theme Surgical innovations for mediastinal tumors arising in the cervicothoracic border region (including thoracoscopic and robot-assisted surgery) Date November 3, 15:30-16:30, Room 5, 3F, Hotel Nikko Kanazawa Outline Surgery for mediastinal tumors arising in the neck to the upper mediastinum is often performed through a median sternotomy, cervical incision, or TMA. Some centers are working to minimize invasiveness by incorporating thoracoscopy and robot-assisted surgery. Because of the overlap with neck tumors such as thyroid tumors and the anatomical complexity of the region, this surgery requires careful attention to safety and postoperative dysfunction as well as radical cure. We would like to share our clinical experience in approaching mediastinal tumors that arise in the cervicothoracic border region, and the pitfalls and innovations of the operation.
Call for Video Workshop	Field Mediastinum Theme Therapeutic strategy for giant mediastinal tumor Date November 4, 8:40-9:40, Room 3, 3F, ANA Crowne Plaza Hotel Outline A radical surgery is the paramount strategy for the treatment of giant mediastinal tumors. As mediastinal tumors may invade the surrounding organs, the tumor and the invaded surrounding tissues should be completely removed to achieve R0 resection. Thus the surgical route and mode should be cautiously planned before surgery. Furtheremore, giant mediastinal tumor sometimes causes fatal respiratory and circulating failure on general anesthesia or intraoperative manipulation. In this session, we will discuss the indication and technique of surgical treatment as well as perioerateve management for giant mediastinal tumor.
Call for Panel Discussion	Field Mediastinum Theme Thymic epitherial tumors: multimodality therapy for metastatic or advanced tumors and new treatments Date November 2, 15:00-16:00, Room 5, 3F, Hotel Nikko Kanazawa Outline Chemotherapy options and efficacy for thymic epithelial tumors have been limited, but lenvatinib has been approved for thymic carcinoma and clinical trils of ICI have been reported. We would like to hear about your experience with novel therapies for thymic epithelial tumors and your experience with salvage surgery. We would also like to discuss perioperative treatment of advanced cases, surgical resection at recurrence, and timing of resection as part of multimodality treatment.
Call for Symposium	Field Tumor Theme Evolution of surgical approaches (Thoracotomy/extended surgery to minimally invasive surgery) Date November 4, 14:15-16:15, Room 2, 2F, Ishikawa Ongakudo Outline Surgical approaches in chest surgery has evolved dramatically from thoracotomy/extended surgery to minimally incvasive surgery. In this session, we hope that speakers discuss about present situations in each surgical approach.
Call for Video Workshop	Field Tumor Theme Surgery for lung cancer invading the adjacent organs Date November 2, 9:40-11:10, Room 8, 4F, Hotel Nikko Kanazawa Outline Surgery for lung cancer invading adjacent organs is a highly invasive treatment depending on the adjacent organ to be resected, but it is also a promising treatment that can be expected to cure if the tumor can be completely removed. However, in recent years, non-surgical treatments such as drug therapy with ICI and molecular targeted drug, and 3D radiation therapy have been progressing. In this session, we would like you to present data from each institution regarding not only surgical techniques but also postoperative complications and long-term prognosis in order to discuss the appropriateness of the procedure including the indication for surgery.
Call for Workshop	Field Tumor Theme Neoadjuvant immune checkpoint inhibitor +chemotherapy for locally advanced NSCLC. -The indication and pitfall- Date November 2, 13:50-14:50, Room 8, 4F, Hotel Nikko Kanazawa Outline Neoadjuvant therapy with ICI is expected to increase the number of cases in the real world due to its favorable clinical trial results. On the other hand, useful biomarkers have not been clarified, and there are a certain number of cases in which surgery becomes inoperable due to iRAE or disease progression. In addition, there are concerns about the problem of advanced adhesions associated with preoperative treatment and complications at frequencies and timings that are different from those in the past. In this session, we would like you to discuss the indications for neoadjuvant therapy with ICI, precautions in surgery, in perioperative management and in postoperative follow-up.
Call for Symposium	Field Chest wall_pleura Theme Malignant Pleural Mesothelioma: Surgical pit fall and postoperative complication Date November 3, 8:00-9:30, Room 5, 3F, Hotel Nikko Kanazawa Outline Multimodality treatment including surgical therapy (EPP or ePD) is applied for resectable mulignant pleural mesothelioma. Presentations regarding with surgical know-how, pit fall, and postoperative complications will be welcome.
Call for Workshop	Field Chest wall_pleura Theme Refractory air leak and pneumothorax Date November 4, 14:15-15:15, Room 3, 3F, ANA Crowne Plaza Hotel Outline Air leaks are one of the conditions that thoracic surgeons have the most experience with, but when they are intractable, they are one of the conditions they least want to experience. From refractory air associated with base lung diseases such as emphysema, interstitial pneumonia, and LAM, to postoperative air leaks involving bronchial transection, and even complications of pyothorax, there are a variety of conditions that can be treated in different ways. We hope that the speakers will provide a meaningful discussion based on their various experiences and help the audience in their clinical practice tomorrow.

Esophageal Surgery

Call for Video Symposium	Field Esophageal Surgery Theme Transthoracic or transmediastinal upper mediastinal lymphadenectomy: benefit and challenge in each approach Date November 4, 9:40-11:15, Room 8, 4F, Hotel Nikko Kanazawa Outline Recently, minimally invasive esophagectomy has been widely performed with transthoracic or transmediastinal approach with or without robot assistance. Magnified view is a common benefit contributing to meticulous lymphadenectomy. In contrast, transthoracic approach needs higher skill in lymphadenectomy along the left recurrent laryngeal nerve (RLN) than the right RLN, while transmediastinal approach has a difficulty in surgical view and handling for lymphadenectomy along the right RLN compared with the left RLN. In addition, intraoperative nerve monitoring is reported to be useful to reduce RLN paralysis in each approach. This session hope for speakers to show surgical techniques of bilateral RLN lymphadenectomy with benefit and knack to overcome the difficulty.
Call for Panel Discussion	Field Esophageal Surgery Theme Indications and limitations of conversion surgery for unresectable esophageal cancer Date November 3, 8:00-9:30, Room 8, 4F, Hotel Nikko Kanazawa Outline Unresectable advanced esophageal cancer, encompassing locally invasive unresectable T4 lesions and distant metastasis (M1b), presents a significant treatment challenge. Recent reports have shown an increasing trend in performing surgery following successful tumor control through multimodality therapy, including immune checkpoint inhibitors and chemoradiotherapy. However, consensus on the indications for surgery, optimal timing of surgery, and post-surgical adjuvant therapy remain elusive.In this session, we will discuss the indications and limitations of conversion surgery based on short- and long-term outcomes at various institutes and will identify important factors contributing to improved prognosis in esophageal cancer.
Call for Workshop	Field Esophageal Surgery Theme New innovations to reduce postoperative complication Date November 3, 15:30-16:30, Room 1, 2F, Ishikawa Ongakudo Outline Postoperative complications in esophageal cancer surgery still occur frequently even in the era of minimally invasive surgery. It has been suggested that postoperative complications may affect not only short-term outcomes but also long-term outcomes such as decreased QOL and poor prognosis, and it is important to reduce postoperative complications. In this session, we would like to present new attempts to reduce postoperative complications and discuss for the establishment of safe perioperative treatment.
