【Abstract】 Objective To summarize the experience of the diagnosis and treatment of double chamber of right ventricle in 18 cases. Methods 18 cases with double chamber of right ventricle underwent orthopedic procedure. Cardopulmonary bypass (CPB) was performed in all cases. Median incision in chest was selected in 14 cases. The mini-incision in right chest and mini-incision in inferior segment of sternum were selected in 2 cases separately. 2 operations were performed without heart arrest. Hypertrophy muscular band was resected and the outflow tract was cleared out. Ventricular septal defect (VSD) and pulmonary valve stenosis (PS) were corrected if necessary. Results Symptoms of 18 patients were alleviated or disappeared. All cases recovered. Conclusions Symptoms of patients with double chamber of right ventricle would become more and more serious with the growing of the age. If patients’ pressure gradient were more than 50 mmHg, operation should be performed as earlier as possible after diagnosis inspired of having symptoms of not. ASD VSD and PS should be corrected at the same time if necessary.更多还原
