We report a rare case of primary cardiac angiosarcoma in the right atrium. A 47-year-old man was admitted to our hospital with cardiac tamponade. Echocardiography and computed tomography revealed a tumor in the right atrial cavity. We performed tumor resection to confirm the histological diagnosis, to prevent tumor embolism, and to increase the possibility of improving the prognosis. The tumor was resected with the right atrial wall and right pericardium. The right atrium was then reconstructed with a bovine pericardial patch. The pathological diagnosis was angiosarcoma. The patient survived only about 6 months after surgical resection, but there was no local recurrence. This report presents a very rare case of cardiac angiosarcoma associated with cardiac tamponade.

The U-40 generation of surgeons are practicing through trial and error, and form various careers. At the 51st Annual Meeting of the Japanese Society of Cardiovascular Surgery, U-40 Special Project, we looked back on the U-40 generation and more senior doctors to see what kind of future visions, problems and careers they have had. We conducted a questionnaire for the purpose of visualizing the future prospects of the U-40 generation. In this article, we report the results.

In the U-40 column, we conducted a questionnaire survey of the U-40 generation on the theme of the specialist system for cardiovascular surgery and reported on the present condition and problems in obtaining certification. With the introduction of a new system, off the job training and participatory training using extracorporeal circulation techniques were newly mandated. In this article, we report the results and discussion of the questionnaire survey regarding the present condition of extracorporeal circulation training for the U-40 generation and the pros and cons of training programs.

We investigated how cardiovascular surgeons get a day off.

A 74-year-old woman was scheduled for total arch replacement because of an enlarging thoracic aortic aneurysm in the aortic arch. Her preoperative blood test showed an elevated cold agglutinin with a titre of 2,048. There was concern about hemagglutination during hypothermia and hemolysis when returning to natural temperature under hypothermic circulatory arrest. We usually use moderate hypothermia (a minimum rectal temperature of 27℃) with circulatory arrest during total arch replacement. A cooling test was performed with her blood, which found no coagulation reaction in vitro at 25℃. There was a possibility that the total arch replacement would be carried out under moderate hypothermia, but it was by no means certain. After discussing the case with the hematologist, anesthetist, and clinical engineer, we decided on a minimum temperature of 30℃ during circulatory arrest because hemagglutination or hemolysis can become an issue in cardiopulmonary bypass. Coronary perfusion was maintained by infusing blood cardioplegia at 30℃ every 30 min. The intra-aortic occlusion balloon was inflated in the descending aorta, and perfusion of the spinal cord and lower body was initiated via the left femoral artery during circulatory arrest. Total selective cerebral perfusion flow was maintained at 1.5 times normal (20 ml/kg/min). There was no hemagglutination or hemolysis during the operation and no neurological complications in the postoperative period. For patients with cold agglutinin, individual cardiopulmonary bypass planning is necessary, depending on the severity of the condition and operative method.
