This study is devoted to a series of 30 anatomical cases of mitral atresia. The left atrium was dilated in 5 cases and hypoplastic in 25. The interatrial ostium was small in 50% of the hearts. Left atrio-ventricular concordance was present in 29 cases, as against 1 case of discordance. There was no atrio-ventricular connection in 29 cases, and the mitral valve was imperforate in 1 case. Connections between the tricuspid valve and the main ventricle were normal in 26 hearts. The tricuspid valve straddled the septum in 4 cases. Five hearts had two ventricles, 25 had a single ventricle. Nine hearts showed no ventriculo-atrial atresia. The main vessels were normally located in 1 case, transposed in 2 and originated in the right ventricle in 2 cases; in the 5 hearts with single ventricle the two main vessels arose from the main cavity. Seventeen hearts had an atresic aortic valve and a hypoplastic ascending aorta; the pulmonary artery arose from the right ventricle in 1 case and from the main chamber of a single ventricle heart in 15 cases. The pulmonary valve was atresic and the aorta arose from the main chamber of a single ventricle heart in 4 cases.
本研究致力于30例二尖瓣闭锁的解剖学病例。5例左心房扩张，25例左心房发育不全。50%的心脏房间隔小孔较小。29例存在左房室一致，1例不一致。29例无房室连接，1例二尖瓣无孔。26例心脏三尖瓣与主心室之间的连接正常。4例三尖瓣跨隔。5例心脏有两个心室，25例有一个心室。9例心脏无室房闭锁。1例主血管位置正常，2例转位，2例起源于右心室；在5例单心室心脏中，两条主血管起源于主腔。17例心脏有闭锁的主动脉瓣和发育不全的升主动脉；1例肺动脉起源于右心室，15例起源于单心室心脏的主腔。4例肺动脉瓣闭锁，主动脉起源于单心室心脏的主腔。
