Surgical treatment of 30 cases with double chambered right ventricle
Abstract：Objective To explore the expericnce of diagnosis and surgical treatment for double chamber right ventricle during past ten years.Methods From January 2006 to July 2016,the 30 cases of patients with double chamber right ventricle who underwent surgical treatment were retrospective analyzed.27 cases were diagnosed preoperatively by echocardiography,and the others were diagnosed intraoperative.In which,type of muscular septum was of 18 cases,muscle bundle was of 12 cases.2 with of double cavity of right heart only,25 cases combinated with interventricular septal defect,2 cases with atrial septal defects,arterial catheter was not closed in 2 cases,aortic valve diaphragm under 1 case.The abnormal right ventricular hypertrophy muscle bundle was surgical removedand ventricular septal defect was reapaired.Not patch widen the right ventricular outflow tract in 8 cases,in 22 cases the right ventricular outflow tract was widen by using autologous pericardium and dacron patch,and the other deformities were corrected at the same time.Results 1 case with adult double chamber right ventricle combined with severe tricuspid valve incompetence died after surgery early,this case with right cardiac insufficiencyclinical symptoms such as bloating and double lower limbs swelling preoperation,and low cardiac syndrome happened postoperation,then died after 2 days.The rest of the patients were with satisfactory effect and rehabilitation.Mortality was 3.33％(1/30).The postoperative follow-up was carried out mainly by the clinic and telephone,the rate was 100％ During the 3 months to 10 years follow-up,there were 2 cases with preoperative mild tricuspid valve insufficiency showedmild to medium tricuspid valve insufficiency which maybe related with the excision of papillary muscle.The surgery effects were satisfied in patients with narrowed right ventricular outflow tract.The right ventricular outflow tract is satisfactory,and no patient has been reoperated due to the narrowing of the right ventricle.The postoperative cardiac function was significantly improved in the whole group,and the activity increased significantly,and the growth and development were improved.Conclusion The surgical treatment for relieving of the narrow of right ventricle outflow tract and correcting the other malformation of the heartwas satisfactory in the near and mid-term effects,and further follow-up was expected.
