This is a report on the anatomical characteristics of 17 cases of tricuspid atresia. Three of these cases had a discrepancy between the type of bulboventricular loop (dextro) and the position of the great arteries (the aorta being to the left of the pulmonary artery). In these a characteristic type of ventricular septal defect, located just beneath the tissue of the semilunar valves was found. In 3 cases with cardiac dextroversion and juxtaposition of the atrial appendages the great arteries were on the same frontal plane and there was a separation between the semilunar and the anterior mitral leaflet. One case was associated with a double outlet left ventricle, a D-malposition of the great arteries, and a bilateral subaortic and subpulmonary conus. Among the 6 cases with transposition of the great arteries, the ventricular septal defect was large in 2 (34.4%) only. In the analysis of the 13 cases with intact ventricular septa (2 cases) or restrictive (small and medium-sized) ventricular septal defects (11 cases) obstructive anomalies of the vessel arising from the right ventricle were found in 12 (92.3%). These anomalies involved the aorta in 4 cases. (34.4%) and the pulmonary artery in 8 (66.6%). In the study of the 4 cases with a large ventricular septal defect, obstructive anomalies in the vessel arising from the right ventricle were present in 2 cases (50%), and were located in the aorta in 1 case (25%) and in the pulmonary artery in the other case (25%). The 2 cases with intact ventricular septum were associated with a hypertrophy of this septum and an absent pulmonary valve. In 1 of these cases, a third ventricular chamber was disclosed within the ventricular septum. This chamber communicated with the right ventricle through a very small opening. In 82.3% of the cases, the projection of the dimple, the rest of the tricuspid orifice, was located either on the ventricular septum or over the left ventricle. In the 3 cases with juxtaposition of the atrial appendages there was a positive transillumination of the floor of the right atrium, which corresponded, to the rest of the tricuspid valve in one case and to the atrioventricular portion of the membranous septum in the other 2.
这是一篇关于17例三尖瓣闭锁解剖特征的报告。其中3例球室襻类型（右襻）与大动脉位置不符（主动脉位于肺动脉左侧）。在这些病例中，发现一种特征性的室间隔缺损，位于半月瓣组织下方。在3例心脏右旋和心耳并列的病例中，大动脉位于同一额面，半月瓣与二尖瓣前叶之间存在分离。1例合并左心室双出口、大动脉D型转位以及双侧主动脉下和肺动脉下圆锥。在6例大动脉转位的病例中，仅2例（34.4%）室间隔缺损较大。在对13例室间隔完整（2例）或限制性（中小尺寸）室间隔缺损（11例）的分析中，12例（92.3%）发现右心室发出的血管存在梗阻性异常。这些异常累及主动脉4例（34.4%），肺动脉8例（66.6%）。在对4例大室间隔缺损的研究中，2例（50%）右心室发出的血管存在梗阻性异常，其中1例（25%）位于主动脉，另1例（25%）位于肺动脉。2例室间隔完整的病例伴有该间隔肥厚和肺动脉瓣缺如。其中1例在室间隔内发现第三个心室腔。该腔通过一个非常小的开口与右心室相通。在82.3%的病例中，表示三尖瓣口其余部分的凹陷投影位于室间隔或左心室上方。在3例心耳并列的病例中，右心房底部有阳性透照，其中1例对应于三尖瓣其余部分，另2例对应于膜性间隔的房室部分。
