左室右房通道是一种特殊的、不常见的心内畸形。其解剖特点,主要是指缺损位于膜部间隔的房室部或/和心室部,后者常合并三尖瓣异常。该缺损多呈卵圆形,光滑;当心室收缩时,左室血液迅即喷射至右心房,因此形成左室与右房相通。有人将此畸形归并于一种特殊类型的室间隔缺损,也有人将它纳入部分心内膜垫缺损之列。本病发病率甚低,据Laurichesse氏统计,占整个先心病的0.08％,易致误诊,常需借助左心室造影确诊。左室右房通道先后由Buhl、
Left atrial and right atrial access is a special, uncommon intracardiac deformity. Its anatomical features, mainly refers to the defect located in the Department of septal atrioventricular or / and ventricular, the latter often associated with tricuspid valve abnormalities. The defect mostly oval, smooth; when the ventricle contraction, rapid injection of blood to the right atrium of the left ventricle, thus forming the left ventricle and right atrium. Someone put this deformity merged into a special type of ventricular septal defect, it was also included in some of the list of endocardial pad defects. The incidence of this disease is very low, according to Laurichesse’s statistics, accounting for 0.08% of the entire congenital heart disease, easy to cause misdiagnosis, often diagnosed by left ventricular angiography. Left atrial and right atrium access successively by Buhl,
