Background: To evaluate the early results of operation for partial atrioventricular septal defect. Methods: Twenty-sevent patients underwent surgical correction of partial atrioventricular septal defect from 1/2011 to 12/2013 at Cardiovascular Centre of Hue Central Hospital. There were 7 (25.9%) female patients and 20 (74.1%) male patients, 18.5% of patients aged < 1 age, 55.6% of patients aged ≥ 1 to 15 years, and 25.9% of patients aged ≥ 16 to 60 years. Sevent (25.9%) had congestive heart failure. There was a primum atrial septal defect in 100% of patients. A cleft of the anterior mitral leaflet was diagnosed in 100% of patients. 92.6% of patients had either moderate or severe mitral incompetence prior to operation. The pulmonary artery systolic pressure exceeded 40 mmHg in 85,.2% of patients. Results: Atrial septal defects were closed with a pericardial patch in 100% of patients. The cleft in its anterior leaflet was closed in 100% of patients. Postoperatively, moderate mitral insufficiency developed in 14.8% of patients. 85.2% of patients have mild mitral incompetence. One patients (3.7%) needed a permanent pacemaker. There was no intraoperative mortality. At 6-9 months postoperatively, left atrioventricular valve insufficiency was moderate in 2 (7.4%) patients and mild in 25 (92.6%) patients who had had cleft closure alone. Conclusions: Repair of partial atrioventricular septal defect is safe and good. It is important to close the cleft in the left atrioventricular valve. The mitral valve should be repaired in a conservative manner. Intraoperative complications occur but are uncommon, suggesting that short-term follow is excellent.
