A 75-year-old man with underlying arteriosclerosis obliterans presented with acute heart failure secondary to rest pain of the right lower extremity. Echocardiogram showed severe mitral regurgitation, moderate tricuspid regurgitation and a low cardiac function (ejection fraction : 27%). Right toe gangrene developed in association with continuous acute heart failure. He underwent mitral valve replacement, tricuspid annuloplasty, right common femoral artery-posterior tibial artery bypass and amputation of the right toes in single-stage surgery. There were no major complications during his hospital stay. After surgery, his symptoms significantly improved.

The transition to the new specialist certification system has progressed in cardiovascular surgery, enabling many surgeons to obtain specialist certification earlier than before. This study focuses on conditions that are particularly easy to overlook factors in the application process, namely academic activities, surgical experience, and Off-the-Job Training (OJT). This report summarizes these changes to facilitate efficient specialist certification applications for trainees.
