Aortic Valve Replacement with Concomitant Coronary Artery Bypass Grafting for an Aortic Stenosis Coexisting with Anomalous Origin of the Coronary Artery / 日本心臓血管外科学会雑誌

<p>Congenital anomaly of the coronary artery is rare. We have to care about the injury of the aberrant coronary artery and ischemic complication during and after the heart valve surgery. We experienced a good clinical course of aortic valve replacement (AVR) with concomitant coronary artery bypass grafting (CABG) for aortic stenosis coexisting with anomalous aortic origin of the right coronary artery. A 72-year-old woman had suffered from dyspnea and palpitation on effort, and we diagnosed severe aortic stenosis. Preoperative examination revealed the right coronary artery arising from the left coronary sinus with a stenotic lesion in the interarterial course between the aorta and main pulmonary artery. She underwent AVR and CABG using a saphenous vein graft. The peripheral anastomosis of the bypass grafting was performed before starting cardiopulmonary bypass and the blood cardioplegia was infused into right coronary artery through the bypass graft during cardiac arrest. The postoperative course was uneventful and the patent bypass graft was confirmed by computed tomographic angiography.</p>

A Case of Infective Thoracoabdominal Aortic Aneurysm with Rapid Expansion during Steroid Therapy for Retroperitoneal Fibrosis / 日本心臓血管外科学会雑誌

A 66-year-old man who suffered from intermittent abdominal and back pain underwent medical examinations at our hospital. A high value of leukocyte, inflammatory reaction and IgG4 was detected, and computed tomography demonstrated that there was thickened soft tissue around the abdominal aorta which extended to the superior mesenteric artery and the renal arteries. He was given a diagnosis of retroperitoneal fibrosis, and prednisolone (PSL) was administered. Although the decrease in thickness of the soft tissue around the aorta was seen, the enlargement of the aorta mainly near the orifice of the celiac artery was shown. We were consulted on this thoracoabdominal aortic aneurysm (Crawford type IV) at this time, and considered that this aneurismal change had occurred secondary to chronic periaortitis. In a few weeks, the rapid expansion of this aneurysm was occurred, so we planned early surgical treatment after tapering of PSL. He underwent graft replacement of thoracoabdominal aorta with rifampicin-bonded graft, because the infection could not be denied as a cause of this aneurysmal change. Although <i>Streptococcus pneumoniae </i>was detected in the specimens from the periaortic tissue, false lumen and aortic wall in the culture test, he had a good post operative course with prolonged antibiotic therapy.
