Case of Unruptured Aneurysm of the Sinus of Valsalva into the Right Atrium with Perimembranous VSD / 日本心臓血管外科学会雑誌

ABSTRACT

An 8-year-old girl had been found to have a congenital ventricular septal defect (VSD), based on the presence of a cardiac murmur from birth. She had a history of infective endocarditis and lung abscess when she was 2 years old. Mild aortic regurgitation was revealed by an echocardiogram in August 2004. Right-heart catherization revealed a step up in the oxygen saturation of the right ventricle, aortography showed a deformity of the noncoronary cusp and mild aortic regurgitation, and Doppler color-flow echocardiography detected progression of aortic regurgitation. The patient underwent surgical repair of the VSD with a cardiopulmonary bypass. Following direct suturing combined with pledgets for perimembranous VSD, infusion of cardioplegia revealed the aneurysmal sac extruding from the wall of the right atrium. The final diagnosis was an aneurysm of the sinus of Valsalva from the noncoronary aortic sinus into the right atrium (type IV of Konno). The aneurysm was sutured by polyethylene strings with pledgets. The postoperative course was uneventful, and echocardiography performed before discharge showed no deformity of the sinus of Valsalva and trivial aortic regurgitation which was less than before surgery. She was discharged on the 7th postoperative day.
