A Case of Intermediate Type Atrioventricular Septal Defect Associated with a Membranous Ventricular Septal Aneurysm in a 70-Year-Old Female Patient / 日本心臓血管外科学会雑誌

The case was a 70-year-old female. Atrioventricular septal defect was diagnosed in her childhood, however, surgical treatment had not been performed. The patient had suffered from heart failure at the age of 69, and she was referred to our hospital for treatment. Her diagnosis was intermediate type atrioventricular septal defect, moderate left atrioventricular valve regurgitation, membranous ventricular septal aneurysm and atrial flutter. An autologous pericardial patch was used to close the ostium primum type atrial septal defect associated with simultaneous covering of membranous ventricular septal aneurysmal wall. Concomitant left and right atrioventricular valvuloplasty and arrhythmia surgery were performed. Her postoperative course was uneventful and the patient was discharged from our department on the 16th postoperative day. To our knowledge, there are few reports of surgery for incomplete type atrioventricular septal defect in the elderly and no report for intermediate type atrioventricular septal defect in Japan. In incomplete type atrioventricular septal defect, symptoms such as supraventricular arrhythmia and heart failure develop according to aging. Reported surgical results in the elderly are quite good, and improvement of excise tolerance is expected. Precise evaluation and proper indication of surgical treatment is mandatory even in older patients.

A Severe Aortic Stenosis and Coronary Calcifications in Alkaptonuria / 日本心臓血管外科学会雑誌

Alkaptonuria is a rare genetic disease, in which amino acids and tyrosine cannot be processed. A 72-year-old man with a history of aortic valve stenosis presented with coronary 3-vessel disease. Intraoperative findings included ochronosis, which is pigmentation caused by the accumulation of homogentistic acids in connective tissues, or on the severely calcified aortic valve, the intima of the aorta, and the coronary arteries. The pigmented region of the coronary arteries had significant stenosis. Aortic valve replacement and coronary artery bypass were performed. From these findings and his past history of arthritis, we diagnosed alkaptonuria. The patient had an uneventful recovery.

Stentgraft Treatment for Inflammatory Aortic Aneurysm of Thoracic Aorta in Behçet's Disease / 日本心臓血管外科学会雑誌

A 71-year-old man with Behçet's disease was admitted to our hospital for treatment of a thoracic aortic aneurysm. On admission, there was marked inflammatory response, but blood culture was negative and there was no significant accumulation of gallium scintigraphy. The aorta was shaggy and there were two aneurysms in the descending aorta. We performed endovascular aortic repair for this aneurysm in consideration of the inflammatory aortic aneurysm. After treatment, the patient had paraparesis, however he underwent physical rehabilitation to regain function. He was followed up for 1 year and remains in good clinical condition without anastomotic aneurysm, dilatation or aneurysm at another site.
