Minimally invasive cardiac surgery in Japan: history and current status

This review examines the historical and current status of minimally invasive cardiac surgery (MICS) in Japan, based on reports that have been published in English. Although enthusiasm for MICS in Japan increased during the 1990s, it waned during the early 2000s because of various limitations. However, the introduction of minimally invasive mitral valve surgery, aortic valve replacement, atrial septal defect closure, and coronary artery bypass has led to the resurgence of MICS in Japan during recent years. Academic societies and a national registry system will play an important role in ensuring that this new wave of MICS is implemented safely and effectively. Off-the-job training and team building are also key factors for implementing a successful MICS program.
