Research objectives: The enlargement of right ventricle results in dilation of tricuspid valve annulus with the presence of the cleft between the anterior leaflet and septal leaflet of the tricuspid valve; according to several authors, it is also called the cleft of septal tricuspid leaflet. Depending on the magnitude, the cleft may cause tricuspid valve regurgitation more or less. | Technique for atrial septal defect repair is one of the fundamental CHD repair surgical techniques. However, because of having the abnormal cardioneurogenic position and conduction, patients with partial AVSD were prone to the complete AV block after the first repair surgery. According to Leca F. (1987) and a number of French authors, in attempt to protect the bundle of His and AV node, the coronary sinus was placedon the left side. Many other studies showed that whether the sinus node was put on the left side or the right side did not impact the onset of complications of conduction. We could reach consensus on this matter of respecting the original position of the coronary sinus, that’s why in our study, in 12 cases, the coronary sinuses on the left originally were remained on the left; in 77 cases, the coronary sinuses on the left originally were remained on the left. As a result, no cases developed postoperative permanent AV block type III. We want to emphasize the importance of respecting the original anatomical structures by closing the atrial septal defect by superficial sutures that went throughout the endothelial layer, all the stiches were close enough to certain the stability of the closure.
