ABSTRACT
The system of the Japanese Board of Cardiovascular Surgery is changing. Since the last time, we have deliberated on the medical specialty board for U-40 column articles about the problems faced by young cardiovascular surgeons. This time, we conducted the second survey to U-40 members about the realities of becoming a board-certified cardiovascular surgeon. The results showed the circumstances and details on how to acquire the board certification. Moreover, we discussed about the current problems and future perspectives for the young cardiovascular surgeons.
ABSTRACT
<p>A 79-year-old man, who had undergone aortic valve replacement due to severe aortic stenosis 2.5 years previously and permanent pacemaker implantation for sick sinus syndrome 2 months after aortic valve replacement, was admitted for congestive heart failure and suspicion of prosthetic valve endocarditis. However, he had a fever in spite of medical therapy, and transthoracic echocardiography revealed a 20 mm vegetation on the posterior mitral valve leaflet. He underwent emergency surgery on a diagnosis of infective endocarditis. The intraoperative examination showed annular abscess on the calcified mitral annulus, and a part of abscess had disintegrated, from which the vegetation arose. We performed maximal possible debridement of the infected tissue and mitral annulus reconstruction with a bovine pericardium. Subsequently, mitral valve replacement and annulus reinforcement with a prosthetic valve collared with a bovine pericardium were performed to prevent perivalvular leakage. The patient showed no recurrence of infection and perivalvular leakage at 1.5 years of follow-up.</p>
ABSTRACT
<p>A 27-year-old man who presented with worsening dyspnea was transferred to our hospital due to congestive heart failure with multiple organ dysfunction. Echocardiogram showed severe left ventricular systolic dysfunction and a huge thrombus in the left ventricle. An urgent operation was performed to remove the thrombus simultaneously with the placement of bilateral extracorporeal ventricular assist devices. After the operation, despite a rapid improvement in the liver function, renal dysfunction persisted and he remained anuric for nearly a month. We continued maximal circulatory support with biventricular assist device to optimize his end-organ function. His renal function gradually improved, allowing him to be registered as a heart transplant candidate on the 140th postoperative day. On the 146th postoperative day, the patient underwent successful removal of the right ventricular assist device, and the left extracorporeal device was replaced by an implantable device (HeartMate II). He was discharged 78 days after the implantation. We present here a case where adequate support with biventricular assist device enabled a successful bridge to transplantation even in a patient with end-stage heart failure having end-organ dysfunction.</p>
