Integrated cardiothoracic team approach for complex lung transplantation procedures in Japan—current status and future direction

The first lung transplant procedure in the world was performed in 1983, while in Japan that was first accomplished in 1998. Over the following 25 years, lung transplantation has become a viable treatment option for Japanese patients with a variety of end-stage lung diseases. Seventy cadaveric-donor lung (41 single, 29 bilateral), 11 bilateral living-donor lobar lung, and three heart-lung transplants have been performed with use of an integrated cardiothoracic team approach at medical facilities associated with Osaka University. Extremely advanced clinical and surgical skill sets are required to complete a lung transplant procedure, including surgical knowledge and techniques, as well as management of cardiovascular surgery, especially in regard to mechanical circulatory support (MCS), vascular anastomosis in difficult cases, and concomitant cardiac surgery. We have found that a collaborative effort by general thoracic and cardiac surgeons is an important key for success with lung transplantation. Complex lung transplant surgery and management in Japan are performed by use of an integrated cardiothoracic team approach, which has led to a synergistic impact on successful lung transplantation cases by capitalizing greatly on the experiences, techniques, and expertise of cardiac and thoracic experts. The present review is focused on the role of cardiac surgeons from the viewpoint of our experience with these cases.
