1. Radical surgery
Ventricular shunt is the earliest radical surgery that can be performed on SV patients. However, due to the limited number of patients suitable for radical surgery, the high rate of surgical mortality and total atrioventricular block, radical surgery is rarely performed.At present, radical surgery is only applicable to patients who have left ventricular SV with left aortic transposition, atrioventricular valves on both sides, and no other heart malformations.9
