With the development of modern surgery, minimally invasive treatment of various surgical diseases has become the mainstream, and the application of lumpectomy technology meets the modern aesthetics and enhances people’s acceptance of “doing surgery”. After 14 years of technical innovation and experience, the advantages of lumpectomy heart surgery are very obvious: first, the wound is beautiful, with only three small incisions of 1-2cm; second, it does not hurt the bones, which will not affect the bone development of children and does not have the weakness of slow healing of bones after sternal splitting in elderly patients; third, the recovery speed is fast, because the surgery is small trauma, which reduces the chance of postoperative bleeding and various infections; fourth, the postoperative hospitalization time is short and the total consumption is low. So, how to choose thoracoscopic means for heart disease treatment? In addition to extracardiac lesions arteriovenous catheterization and atrial fibrillation, including atrial septal defect, ventricular septal defect, partial type atrial septal defect, partial type pulmonary vein ectopic connection, triple atrial heart, tricuspid valve subluxation malformation (mild to moderate), aortic sinus aneurysm rupture (rupture to the right atrium or perimembranous part), etc. 1, congenital heart disease ① atrial septal defect: all atrial septal defects that cannot be treated by intervention can be treated by thoracoscopic surgery. ② Ventricular septal defect: simple perimembranous septal defect cannot be treated by intervention. The main target of lumpectomy arteriovenous catheter clamping is infants and children whose lesions affect development and whose diameters are <8 mm, and the clamping is usually performed in non-extracorporeal circulation via the left chest. < span=""> ④ Atrioventricular septal defect: partial type of atrioventricular septal defect. ⑤ Pulmonary vein ectopic connection; partial type pulmonary vein ectopic connection, intracardiac type complete type pulmonary vein ectopic connection. (6) Triatrial heart: left-sided triatrial heart. (vii) Non-apical coronary venous sinus syndrome. 2.Heart valve disease Simple mitral valve lesion or/and tricuspid valve lesion, 3.Atrial mucinous tumor 4.Atrial fibrillation Paroxysmal and persistent atrial fibrillation are better treated, permanent atrial fibrillation with standard maze radiofrequency surgery is better, still need long-term efficacy observation. 5, the application of lumpectomy composite surgery ① full lumpectomy + interventional blocking: for suitable for full lumpectomy or lumpectomy-assisted minimally invasive cardiac surgery, if combined with arteriovenous catheter failure, can first catheter intervention, and then correct the intracardiac malformation under lumpectomy. (2) Lumpectomy + small extrapleural incision: atrial septal defect combined with pulmonary valve stenosis, electrocardiogram with right ventricular hypertrophic strain and systolic pressure difference between the right ventricle and pulmonary artery exceeding 50 mmHg are indications for surgery.
