Abstract
Background: The association of the Tetralogy of Fallot (TOF) with a Complete Atrioventricular Septal Defect (CAVSD) occurs in 5-10% of hearts with CAVSD. In this paper, we describe the early results of a modification of the double patch technique in which we augment the LAVV leaflet using the patch used for the VSD closure in the repair of CAVSD with TOF.Patients and Methods: Between 2012 and 2014, 12 consecutive patients with CAVSD associated with TOF underwent complete repair were retrospectively reviewed. A double patch technique with LAVV leaflet augmentation was used in all the patients. Tetralogy of Fallot repair included transannular patch in 11 (65%) patients and valvesparing in 6 (35%) patients.Results: Mean age was 25 months ± 18.8, 7 males. Mean weight was 25 kg ± 18.8. Mean pulmonary artery annulus z-score was -1.2 ± 2. The mean preoperative RVOT gradient was 74 ± 18 mm Hg. The in-hospital mortality rates were 20% (2 out of 10). Mean ICU STAY time was 4.5 ± 3.5 days. Mean Mechanical ventilation time was 18 hours ± 10.3. Mean Hospital Stay was 12.5 days ± 5. Pulmonary Regurge was mild in 4 patients (40%) andmoderate in the remaining six patients (60%). Postoperative (Left AV Valve Regurge) was mild to moderate in all the corrected patients. Mean follow-up was 10 ± 3.1 months (range 4 to 14 months).Conclusion: Complete repair with this technique offer an acceptable early outcome regarding mortality, and degree of LAVV regurge.
