[Aortic valve repair surgery: a historical review, current analysis, and future prospects].

Abstract

Aortic valve repair surgery is an ancient surgical approach. It is ancient in the sense that it emerged alongside aortic valve replacement surgery, but was gradually abandoned due to suboptimal outcomes. Currently, aortic valve replacement surgery has become the preferred method for treating patients with aortic valve dysfunction, with or without aortic root lesions. However, due to the risks of prosthetic valve deterioration and anticoagulation-related complications, aortic valve repair surgery has re-emerged as an attractive treatment option, avoiding the long-term risks associated with prosthetic valves. However, it comes with the risk of recurrence of valve regurgitation. Remodeling and reimplantation are milestones in aortic valve repair, reducing the risk of aortic regurgitation. The concept of functional anatomy of the aortic root and the mechanism of aortic regurgitation lay the theoretical foundation for modern aortic valve repair. Aortic valve repair has become a comprehensive repair strategy that involves the basal ring, sinus, sino-tubular junction, and aortic lobes. The long-term survival rate is close to that of the normal population, and the valvular-related reintervention rate is comparable to that of valve replacement. Aortic valve repair is gradually becoming a novel alternative treatment for patients with aortic valve insufficiency, with or without aortic root lesions.
