Key result

Mitral valve re-repair was successfully accomplished in 85% of patients with failed non-rheumatic mitral valve repair, yielding a 4-year patient survival of 97%.

Why the study?

Does mitral valve re-repair improve survival and freedom from moderate mitral regurgitation in adults with failed non-rheumatic mitral valve repair?

Implication

Supports re-repair feasibility after failed non-rheumatic repair; leaves open need for comparative trials versus replacement.

Key Points

To evaluate the feasibility and mid-term outcomes of adopting valve re-repair as a primary strategy for failed non-rheumatic mitral valve repairs.
Analyzed 53 consecutive adult patients undergoing reoperation for failed non-rheumatic mitral valve repair by a single surgical team.
Assessed underlying primary etiologies including degenerative (n=38), congenital (n=6), infective (n=3), functional (n=1), and unknown (n=5) causes at a median interval of 3 years (IQR 0.9–6.5 years).
Attempted re-repair using standard surgical techniques when the anterior leaflet was sufficiently pliable and recurrent lesions were identifiable and treatable.
Failure etiologies included technical failure in 38% (n=20), disease progression in 36% (n=19), and new disease in 26% (n=14).
Valve re-repair succeeded in 85% of cases (45 of 53; 90% in degenerative vs 73% in non-degenerative cases), with 0% in-hospital mortality and a 4-year survival rate of 97%.
Freedom from moderate mitral regurgitation was 100% at discharge, 95% at 1 year, 88% at 3 years, and 80% at 4 years, with zero reoperations during follow-up.

Does mitral valve re-repair improve survival and freedom from moderate mitral regurgitation in adults with failed non-rheumatic mitral valve repair?

Population

53 consecutive adults undergoing reoperation by a single surgical team for failed non-rheumatic mitral valve repair (primary etiology: degenerative n=38, congenital n=6, infective n=3, functional n=1, unknown n=5) at a median interval of 3 years from primary repair.

Intervention

Mitral valve re-repair using standard repair techniques

Outcome

Success rate of valve re-repair, patient survival, and freedom from moderate mitral regurgitation up to 4 yearshard clinical

Mitral valve re-repair is a feasible and effective strategy for failed non-rheumatic mitral valve repairs, achieving high success rates and acceptable mid-term outcomes.
