What does this research mean for the field?

Recurrent mitral regurgitation after mitral valve repair occurs in approximately 9% of cases and is primarily driven by procedure-related factors, such as incomplete repair, and valve-related factors, predominantly the progression of rheumatic disease. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To analyze the incidence, clinical outcomes, and underlying mechanisms of recurrent mitral regurgitation following mitral valve repair.

Implication

Warrants close post-repair surveillance in rheumatic disease; leaves open refinements to reduce both procedural and progression-related failures.

Key Points

To analyze the incidence, clinical outcomes, and underlying mechanisms of recurrent mitral regurgitation following mitral valve repair.
Evaluated 437 patients undergoing mitral valve repair between January 1994 and January 2002 for degenerative (54%), rheumatic (31%), or other (15%) mitral regurgitation.
Surgical techniques included ring annuloplasty (95%), new chordae formation (50%), and quadrangular resection (27%), with a mean follow-up of 29.04 ± 22.81 months.
Recurrent mitral regurgitation occurred in 41 patients (9%) with an overall reoperation rate of 1.6%, alongside 5 early deaths (1.2%) and 5 late deaths (1.2%).
Recurrence mechanisms included 22 procedure-related failures (incomplete repair in 13, discordant chordal length in 7, suture dehiscence in 1, leaflet perforation in 1) and 19 valve-related failures (rheumatic disease progression in 18, endocarditis in 1).

Structured PICO

Population

437 patients with mitral regurgitation (54% degenerative, 31% rheumatic, 15% other)

Intervention

Mitral valve repair (ring annuloplasty in 95%, new chordae formation in 50%, quadrangular resection in 27%)

Outcome

Recurrent mitral regurgitationhard clinical

Recurrent mitral regurgitation after surgical repair occurs in approximately 9% of patients, driven by both procedure-related factors and progression of rheumatic disease, emphasizing the need for intraoperative transesophageal echocardiography.
