A 39-year-old woman with Marfan's syndrome was referred with a symptom of exertional dyspnea, had mitral valve regurgitation, annuloaortic ectasia with aortic valve regurgitation and Stanford B type chronic aortic dissection. She was successfully treated with a one-stage operation, consisting of aortic root replacement with the Carrel patch method, mitral valve replacement and extended replacement of the thoracic aorta (ascending, arch and thoracic descending aorta), through median sternotomy and left antero-axillary thoracotomy. This operation was performed under hypothermic circulatory arrest with continuous retrograde cerebral perfusion. The postoperative course was uneventful. Although the operation may include complicated procedures, it is important to perform a sufficient operation corresponding to the patient's condition and lesions, employing the most advanced surgical techniques, such as circulatory arrest, myocardial protection and so on.

A 67-year-old man was referred to our department for surgical treatment of ischemic cardiomyopathy. Chest X-ray showed cardiomegaly with a cardiothoracic ratio of 62% and pulmonary congestion. CAG revealed multiple obstructive lesions in the left coronary artery system. LVG and UCG showed ventricular dilatation and dysfunction. ECG showed complete left bundle branch block with a QRS duration of 180ms. He underwent autologous bone marrow cell implantation and biventricular pacing concomitant with coronary artery bypass grafting. He is doing well after 15 months without any complications. Combination with therapeutic angiogenesis and cardiac resynchronization therapy may contribute to the development of new regenerative strategy for patients with severe ischemic cardiomyopathy.

We evaluated the efficacy of sternal coaptation pins used to improve the fixation of the transected sternum after coronary artery bypass grafting (CABG) with the internal thoracic artery (ITA). The subjects were 37 patients who underwent scheduled single CABG with ITA in our department and they were classified into two groups, i. e., Group A, without sternal pins (18 patients), and Group B, with sternal pins (19 patients). The efficacy was assessed by the following measurements : drain bleeding volume up to 12 and 24 h after ICU admission, the time until the removal of drain, surgical site infection (SSI) and the maximum split level between the sternal body and manubrium after surgery. Drain bleeding volume up to 12 and 24 h after ICU tended to be less in Group B. The time until the removal of drain was significantly shorter in Group B. SSI was 17% in Group A but 0% in Group B. The use of sternal coaptation pins reduced misalignment of the coapted sternum, and we belive that the use of sternal coaptation pins contributed to the early removal of drain, and SSI reduction.

A 51-year-old man, with an abnormal shadow on chest X-ray film, was found to have a right-sided aortic arch with mirror-image branching and Kommerell's diverticulum. Neither congenital heart anomalies nor vascular ring was observed. We performed descending aorta replacement with a HemashieldTM 24-mm graft, because the trachea and esophagus were compressed by the diverticulum, and to eliminate the risks of aneurysmal change or rupture. The operation was performed through right thoracotomy, and with total CPB under deep hypothermic circulatory arrest. The patient was discharged on the 18th postoperative day. This is rare adulthood case of right aortic arch with Kommerell's diverticulum and no anomalies in the heart.
