Clinical application of minimally invasive cardiac surgery in secondary or multipal heart surgery / 中华胸心血管外科杂志

ABSTRACT

Objective To review and analyze minimally invasive right thoracotomy and peripheral cannulation as an alternative strategy in redo heart surgery.Methods From June 2012 to December 2016, 23 reoperative heart procedures were performed through a right lateral thoracotomy with about 5 cm in the third or fourth intercostal space,according to the different diagnosis with the corresponding operations.Results We performed 23 redo heart surgeries,there were 10 female and 13 male patients with a mean age of 41.43 years(range,20 to 69 years).4 mitral perivalvular leakage, 1 prosthetic valve dysfunction, 3 mitral insufficiency after mitral valvuloplasty, 1 aortic insufficiency after ventricular septal defect and aortic repair, 1 mitral insufficiency after ventricular and atrial septal defect repair, 3 residual fistula after surgery repair of ventricular septal defect, 1 tricuspid insufficiency after mitral and aortic valve replacement, 1 tricuspid insufficiency after left atrial myxoma removal,1 tricuspid insufficiency after Bentall surgery, 2 tricuspid insufficiency after mitral valve replacement, 1 mitral insufficiency after ventricular septal defect and mitral valvuloplasty, 2 tricuspid insufficiency after the repair of Ebstein abnormality.We respectively carried out repair of valve leakage, mitral valve replacement, aortic valve replacement, mitral valve repair, tricuspid valvuloplasty, postoperative repair of residual shunt of ventricular septal defect, redo repair of Ebstein abnormality.The effect of the whole group operation of operation was satisfactory, no death during operation and severe complications.All patients were under cardiopulmonary bypass,three patients' ascending aortas were bloked, and nine patients were with cardiopulmonary bypass.It indicated tha the operation was possible at operation time,total blood loss and the frequency of blood transfusion.Conclusion The application of closed thoracic cardiopulmonary bypass and minimally invasive right thoracotomy in redo or multiple cardiac surgery,can avoid reoperative sternotomy risk such as hemorrhage, tissue damage and so on.It shortened the operation time, reduced the risk of surgery and blood transfusion rate, can be used in some of the heart surgery patients again and repeatedly.
