Cardiac insufficiency is an incomplete closure of the valves of the heart, which needs to be treated by valve replacement or valve repair. 1. Valve Replacement: This is an operation to replace a prosthetic mechanical valve made of synthetic material or a prosthetic biologic valve made of biologic tissue, referred to as valve replacement. Valve replacement can effectively improve heart function and quality of life, as well as resolve the symptoms brought about by heart valve closure insufficiency. 2. Valve Repair: This is a procedure that can restore the normal anatomical shape and physiological function of the heart valves and resolve the symptoms of heart valve closure insufficiency by separating the adhesions at the junction of the valves, separating the adhesions of the tendon cords, shortening, lengthening, or transplanting the tendon cords, partially resecting the valve leaflets and sewing up the leaflets, shrinking the valve annulus or sewing up the valve annulus, and placing a prosthetic ring in the heart valve to restore normal anatomical shape and physiological function of the heart valves. If the diagnosis of cardiac insufficiency is confirmed, early standardized treatment is recommended to reduce the adverse effects of the disease.
