the number of patients undergoing robotic MV repair in Japan is estimated to increase. We expect that our report will be a landmark national study. We present the early and midterm clinical outcomes of patients undergoing TERMVR; we also evaluated their postoperative complications and long-term outcomes. Methods This study was approved by the Institutional Review Board of NewHeart Watanabe Institute, Japan. Written informed consent was given by all participants before the study. The da

Pectus excavatum (PE) can be associated with cardiac disorders that also require surgical repair. Totally endoscopic robot‐assisted mitral valve plasty for mitral valve regurgitation was performed while elevating the sternum with the aid of our original electrical sternum lifting system. Then, the Nuss procedure was performed successfully via small incision. Simultaneous robot‐assisted cardiac surgery and the Nuss procedure is effective. Sternal elevation during cardiac surgery is very important for a safe procedure. The Nuss technique prevents perioperative cardiac compression and allows for correction of the pectus deformity with good cosmetic and functional results.

Subzero nonfreezing preservation using a variable magnetic field resulted in a remarkable suppression of anaerobic metabolism and myocardial protection in porcine hearts.

Our results suggest that, in addition to morphological improvement, C-tube implantation can functionally improve the injured phrenic nerve by promoting phrenic nerve regeneration.
