title: Off-pump occlusion of trans-thoracic minimal invasive surgery (OPOTTMIS) on simple congenital heart diseases (ASD, VSD and PDA) attached consecutive 210 cases report: a single institute experience.
abstract: OBJECTIVE
  This paper intends to report our experiences by using an operation of off-pump occlusion of trans-thoracic minimal invasive surgery (OPOTTMIS) on the treatment of consecutive 210 patients with simple congenital heart diseases (CHD) including atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA).
  
  
  METHODS
  The retrospective clinical data of OPOTTMIS in our institute were collected and compared to other therapeutic measures adopted in the relevant literatures. After operation, all the patients received electrocardiography (ECG) and echocardiography (echo) once a month within the initial 3 months, and no less than once every 3 ~ 6 months later.
  
  
  RESULTS
  The successful rate of the performed OPOTTMIS operation was 99.5%, the mortality and complication incidence within 72 hours were 0.5% and 4.8%, respectively. There were no major complications during peri-operation such as cardiac rupture, infective endocarditis, strokes, haemolysis and thrombosis. The post-operation follow-up outcomes by ECG and echo checks of 3 months to 5 years showed that there were no III° AVB, no obvious Occluder migration and device broken and no moderate cardiac valve regurgitation, except 1 VSD and 1 PDA with mild residual shunts, and 2 PDA with heart expansion after operation. However, all the patients' heart functions were in class I~II according to NYH standard.
  
  
  CONCLUSIONS
  The OPOTTMIS is a safe, less complex, feasible and effective choice to selected simple CHD patients with some good advantages and favorable short-term efficacies.
