Introduction: Follow-up results of patients with partial-intermediate atrioventricular septal defect (AVSD) operated in 1996-2016 at Baskent University are presented.

Patients and Methods: Data obtained from hospital records consists of echocardiographic and angiographic details before surgery, age and weight at surgery, operative details, presence of Down’s syndrome, details of postoperative care, early postoperative and latest echocardiographic findings and hospitalization for reinter- vention.

Results: One hundred seventy eight patient-files were reviewed including 41.6% (n= 74) male, 58.4% (n= 104) female patients. The mean age of patients were 47.09 ± 44.25 (median, 30; 25 and 75 percentiles, 17 and 66.5, respectively) months. The mean body weight during the operation was 15.00 ± 11.22 (median, 11; 25 and 75 percentiles, 8.27 and 17, respectively) kg. Study group included 152 patients (85.3%) with partial AVSD and 26 of patients (14.7%) with partial AVSD. A total of 39 patients (19.1%) were diagnosed with down syndrome. Associated cardiac anomalies were present in 21.3% of patients. Operative technique was modified single-patch technique (Wilcox) in 14.6% (26 patients), pericardial patch in 25.8% (128 patients) and pericar- dial patch and annuloplasty in 13.5% (24 patients). The cleft in the left atrioventricular (AV) valve was closed in 92.1% all of patients.The early mortality and morbidity in the postoperative first month were calculated as 5.6 and 21.2% and the late mortality (> 1 month) and morbidity rates were calculated as 1.2% and 17%, re- spectively. The most common cause of late morbidity was left AV valve insufficiency, left ventricular outflow tract obstruction and therefore reoperations (15.2%).
