Objectives: This report was to evaluate the effectivity and early results of total endoscopic closure for atrial septal defect in children ( with 3 trocars)Abstract: Atrial Septal Defect is the most common congenital heart disease. Minimally invasive cardiac surgery is being perfomed routinely at several cardiovascular centers in Vietnam. At E Cardiovascular Center, from 2016 to 2019 , we performed total endoscopic closure for atrial septal defect in children with 4 trocars. From 2020 to now, we have reduced the number of trocars to 3.Method: Twelve children underwent ASD closure from 1/2020 to 8/2022, with mean age is 7.7 year olds ( ranger from 2.5 to 11) ; mean weight is 20.8 kilograms (ranger from 12 to 40). All the patients have underwent peripheral cardiopulmonary bypass ( CPB)Result: The mean peripheral circulation time was 70 minutes ( range from 56 to100 minutes) on beating hearts. There were 16 cases with patch- closure and 4 cases with direct- closure. After operations, we checked by echocardiography, full of atrial septal defects were closed with no residual shunt , the common femoral arteries at the canula position were normal and not stenosis.Conclusion: Totally endoscopic closure for ASD on beating hearts with 3 trocars is save with a very good shorterm results.
