Surgery for left ventricular outflow tract obstruction carries some risk, but the risk factor is small. Left ventricular outflow tract obstruction may be caused by increased myocardial oxygen consumption, poor coronary blood flow, or stenotic lesions of the coronary artery orifices, etc. The obstruction sites are mainly in the aortic valve, supra-aortic valve, and sub-aortic valve. If the left ventricular outflow tract obstruction is more serious, surgery is needed to relieve the obstruction as soon as possible, but the surgery has certain dangers, which can easily cause bleeding, infection, injury or perforation of the ventricular septum. Therefore, for left ventricular outflow tract obstruction surgery, it is recommended to go to a regular hospital and choose a surgeon with a high level of professionalism to ensure the safe operation of the surgery and to try to avoid the possible dangers during and after the surgery. After the surgery, we should also strictly follow the doctor’s instructions for nursing care and regular checkups to avoid postoperative infections and other complications, in order to ensure the effectiveness of the surgical treatment.
