Cardiac allograft vasculopathy (CAV) is a major cause of mortality after transplantation. We treated a 44-year-old female with off-pump coronary artery bypass grafting (OPCAB) 4 years after heart transplantation. Annual examinations, including coronary angiography and intravenous ultrasound (IVUS), revealed a severe lesion in the left main trunk. The left internal mammary artery was successfully anastomosed to the left anterior descending artery in an off-pump manner. To ensure that patients have a good long-term outcome after heart transplantation, routine examinations, including IVUS, are crucial, because of the nature of CAV. OPCAB is a good option for a left main trunk lesion due to CAV. [ABSTRACT FROM AUTHOR]

Dilated cardiomyopathy (DCM) is a heart muscle disease characterized by progressive heart failure, and is a leading cause of mortality and morbidity. Recently, cellular therapy for end-stage heart failure has been emerging. We herein report a 56-year-old male who received a transplant of autologous myoblast sheets manufactured in temperature-responsive culture dishes. His clinical condition improved markedly, leaving him without any arrhythmia and able to discontinue using a left ventricular assist system and avoid cardiac transplantation. These findings suggest that cellular therapy using myoblast sheets is a promising new strategy for treating patients with end-stage DCM. This method might be an effective alternative to heart transplantation in the near future. [ABSTRACT FROM AUTHOR]

A postoperative pseudoaneurysm is a rare complication that is difficult to diagnose. Computed tomography (CT) revealed a pseudoaneurysm in the ascending aorta of a 68-year-old female 8 days after mitral valve replacement and tricuspid annuloplasty. The defect was simply repaired during emergency surgery without cardiopulmonary bypass (CPB). The early detection of a postoperative pseudoaneurysm is important to avoid a second operation complicated by adhesions. Enhanced CT was useful for early detection in this patient. Pseudoaneurysm of the ascending aorta at the cannulation site can occur soon after surgery, and early recognition might allow simpler surgery without CPB. [ABSTRACT FROM AUTHOR]
