Progress in the treatment of subarterial ventricular septal defect.

Ventricular septal defect is the most common congenital heart disease in children. Among them, doubly committed ventricular septal defect (dcVSD) can be accompanied by aortic valve lesions in the early stage due to its particular anatomical structure. With its low self-healing, once diagnosed, it needs to be treated timely. Currently, the interventional treatment of proper femoral vein radiation intervention in the department of cardiology is challenging to operate. The scope of application is small, and dcVSD is mainly treated by extracorporeal bypass and transthoracic occlusion. The indications, surgical experience, and prognosis of surgery are summarized.
