Key result
Surgical repair of the anterior mitral valve leaflet can achieve good outcomes for mitral regurgitation when performed at centers with expertise.
Why the study?
Approaches for repairing the anterior mitral valve leaflet are not widely established, and fewer studies have evaluated its natural history and treatment options because it is less common and more difficult to repair than posterior leaflet disease.
Does surgical repair of the anterior mitral valve leaflet improve outcomes in patients with mitral regurgitation?
Does surgical repair of the anterior mitral valve leaflet improve outcomes in patients with mitral regurgitation?
Surgical repair of the anterior mitral valve leaflet can achieve good outcomes in expert centers, supporting early repair consideration similar to posterior pathology.
Anterior leaflet repair may be feasible with good outcomes in expert centers; leaves open need for prospective trials versus posterior leaflet standards.
Mitral regurgitation is one of the most prevalent valvulopathies with a disease burden that incurs significant healthcare costs globally. Surgical repair of the posterior mitral valve leaflet is a standard treatment, but approaches for repairing the anterior mitral valve leaflet are not widely established. Since anterior leaflet involvement is less common and more difficult to repair, fewer studies have investigated its natural history and treatment options. In this review, we discuss surgical techniques for repairing the anterior leaflet and their outcomes, including survival, reoperation, and recurrence of regurgitation. We show that most patients with mitral regurgitation from the anterior leaflet can be repaired with good outcomes if performed at centers with expertise. Additionally, equal consideration for early repair should be given to patients with mitral regurgitation from both anterior and posterior pathology. However, more studies to better evaluate the efficacy and safety of anterior mitral valve leaflet repair are needed.

Bahiraie et al. (2024) conducted a review in Mitral regurgitation involving the anterior leaflet. Surgical repair of the anterior mitral valve leaflet was evaluated on Survival, reoperation, and recurrence of regurgitation. Surgical repair of the anterior mitral valve leaflet can achieve good outcomes for mitral regurgitation when performed at centers with expertise.
