Abstract
BACKGROUND: "Swiss Cheese" ventricular septal defects (VSDs) is a kind of rare and complex congenital heart defects and the surgical management remains controversial and a challenge. We reviewed our preliminary clinical experience on biventricular surgical repair of "Swiss Cheese" VSDs with two-patch and right ventricle apex excluding technique in 10 cases. METHODS: From May 2014 to December 2019, a series of 10 patients (M/F = 3/7) were admitted in our center. Nine cases underwent one-stage surgical repair with two-patch and right ventricle apex excluding technique and 1 case received two-stage surgical repair with the same technique. Surgical repair was done with cardiopulmonary bypass (CPB) in all cases. Two fresh autologous pericardium patches were used to close defects of the outflow tract area and the apex trabecular area respectively and as a result, the right ventricular apex was excluded from the right ventricular inflow tract. RESULTS: All operations were successful. Median CPB time and aortic clamping time were 96 min and 68 min respectively. Delayed chest closure was performed in 2 cases within 48-72 h postoperatively. The Median time of mechanical ventilation and ICU stay were 131.3 h and 8 days respectively. Median length of hospital stay after operation was 11 (9-42) days. There was no mortality and major complication except for 2 cases of ventilator associated pneumonia. There was no death and major complication during a median follow-up time of 3.2 years.. The latest echocardiography results showed the left and right heart function was normal in all the cases. CONCLUSIONS: Biventricular surgical repair of "Swiss Cheese" VSDs with two-patch of fresh autologous pericardium and right ventricle apex excluding technique in infants is safe and feasible with favorable early and mid-term results. Long term results need to be evaluated with more cases.
