aortic valve-sparing surgery
Also written as: VSRR — Valve-Sparing Root Replacement
Surgical procedure preserving the native aortic valve while replacing the diseased aortic root.
Full Definition
Aortic valve-sparing surgery encompasses surgical techniques that preserve the patient's native aortic valve cusps while replacing the diseased aortic root and/or ascending aorta. The two primary approaches are the reimplantation procedure (David operation) and the remodeling procedure (Yacoub operation), each with specific advantages and indications. These procedures are ideal for patients with aortic root dilatation but structurally normal valve cusps, allowing preservation of native valve function while addressing root pathology.
Usage
Usage note: Often abbreviated as VSRR; specify technique used (David vs. Yacoub) when known.
