Abstract
Supravalvular aortic stenosis is an uncommon, congenital narrowing of the ascending aorta which originates just distal to the level of the ostium of the coronary artery. We conducted a successful surgical treatment in a 39 year- old female patient with a congenital supravalvular aortic stenosis and aortic regurgitation who did not show signs of William's syndrome. After we performed an inverted Y-shaped aortotomy toward the noncoronary sinus and right coronary sinus, pantaloon shaped prosthetic patch(Vascutek, Ino, USA) was used to repair the narrowing sinotubular junction. The aortic valve was replaced concommittently using Sorin Bicarbon 19mm. Her postoperative course was uneventful. The patient discharged at 9th postoperative day in good health.
대동맥판상부 협착증은 발살바동 상부에서부터 협착이 존재하는 비교적 흔치않은 선천성 질환이다. William 증후군없이 선천적으로 대동맥판 상부 협착증과 대동맥 좌관상판엽의 형성부전으로 인한 대동맥판 폐쇄부전증으로 진단받은 39세 여자환 悶“\ulcorner대동맥판막 치환술 및 Vascutek graft를 이용한 판탈롱 대동맥성형술을 시행 하였다. 환자의 술후경과는 좋았고 술후 9일째 퇴원하였다.
