CONGENITALLY QUADRICUSPID AORTIC VALVE--ANALYSIS OF 6 NECROPSY PATIENTS

先天性四叶瓣是一种罕见的瓣膜，通常会引起 无瓣膜功能障碍。我们研究了6例四尖瓣病变患者。 主动脉瓣。一只四尖瓣主动脉瓣严重 反流性的，需要手术替换。剩下的5个 瓣膜功能正常，这5名患者均死于 一种非心脏疾病。其他先天性心脏畸形 在6名患者中有2名患者出现：病例1有“脑室” 房间隔缺损“，已自动闭合，病例2有 先天性二尖瓣后1/2缺陷症 小叶，上面没有附着腱。附属品 所有6例患者的牙尖均小于其他3个牙尖。 它们的大小相似。附件尖端位于 4例患者的右侧和后部牙尖位于左侧和后部之间 情况1中的后尖点，以及情况1中的左右尖点之间 例2.5例患者的右冠状动脉占优势 他的冠状动脉优势已为人所知。

Congenitally quadricuspid aortic valves are rare and usually cause no valvular dysfunction. We studied 6 patients with quadricuspid aortic valves. One quadricuspid aortic valve was severely regurgitant, necessitating surgical replacement. The 5 remaining valves functioned normally and each of these 5 patients died from a non-cardiac condition. Other congenital cardiac abnormalities were present in 2 of the 6 patients: case 1 had a "ventricular septal defect" which had closed spontaneously and case 2 had a congenitally deficient posterior one half of the anterior mitral leaflet and no attached chordae tendineae to it. The accessory cusp in all 6 patients was smaller than any of the other 3 cusps which were similar in size. The accessory cusp was between the right and posterior cusps in 4 patients, between the left and posterior cusps in case 1, and between the right and left cusps in case 2. The right coronary artery was dominant in the 5 patients in whom coronary dominance was known.
