Surgical treatment of double outlet ventricle

Objective To study the results of surgical treatment for double outlet ventricle. Methods The results of 72 cases of double outlet ventricle were retrospectively analyzed. Results There were 71 cases of double outlet right ventricle, including 64 cases of type SDD, 3 type ILL, 3 type SDL, 1 type IDD. Only one case was double outlet left ventricle type ILD. Surgical procedures included left ventricle-aorta intraventricular tunnel connection in 61 patients,total cava-pulmonary artery connection in 2,left ventricle-aorta intraventricular tunnel and right ventricle-pulmonary artery extracardial tube repaired in 3. Six cases underwent bi-directional Glenn procedure. Two cases died from operation. Residue shunt of VSD was observed in one case and re-operation was done to repair the shunt. There were no long-term death and other complications. Conclusion It is important to choose the right time and proper procedure. Reconstruction left and right ventricle is the essential factor to the surgical success. 6 refs
