Does mitral valve repair improve very long-term survival compared with mitral valve replacement in patients with severe MR due to MVP?
Mitral valve repair should be the preferred surgical correction for severe MR due to MVP as it improves very long-term survival compared to replacement.
In severe MR due to MVP, mitral valve repair compared with MVR provides improved very long-term survival after surgery for both AL-MVP and PL-MVP. Reoperation is similarly required after repair or replacement but is more frequent after repair of AL-MVP. Recent improvement in long-term durability of repair suggests that it should be the preferred mode of surgical correction of MVP whether it affects anterior or posterior leaflets and is an additional incentive for early surgery of severe MR due to MVP.
