The results of total repair for tetralogy of fallot with an abnormal coronary artery

Abstract

The objective of this study evaluated the results of total repair for tetralogy of Fallot with an abnormal coronary artery.
 Methods: This was a review of seri Tetralogy of Fallot with an abnormal coronary artery cases who underwent total repair from 1/2018 to 6/2023.
 Results: There were 10 patients who underwent complete surgical repair, include 6 males and 4 females. The mean age was 6,8 months (range 4 months to 17 months)and the mean weight was 7,2 kilograms. 6 patients had Left Anterior Descending (LAD) artery originating from Right Coronary Artery (RCA), 3 patients with RCA originating from LAD and 1 patient with one major banche of RCA crossing the infundibulum. There were 7 patients with Pulmonary Valve Preserve (PVP) and 3 patients with Conduit Using (CU). The time of cardiopulmonary bypass, aortic clamping and ventilator were: 90 mins; 63 mins and 16 hours. There was not intrahospital mortality. Echocardiography post -operation: in PVP group all patient had a competence pulmonary valve and mean gradient was 12,5 mmHg; in CU group, there were not pulmonary valve regurgitation and mean gradient was 9 mmHg. During follow-up time 30 months after surgery, there was no late death; 2 patient in PVP group who had moderate pulmonary valve regurgitation and mean gradient was 22 mmHg; in CU group, there was a competence pulmonary valve with mean gradient 26 mmHg.
 Conclusion: There was a good result of total repair for tetralogy of Fallot with an abnormal coronary artery.
