Key result

Surgical mitral valve repair delivers excellent long-term survival and low reoperation rates across diverse pathologies.

Why the study?

Although outcomes following surgical mitral valve repair are well described, longitudinal follow-up is heterogeneous, and long-term data are vital to better advise treatment and counsel patients.

Structured PICO

P

Population

Narrative review summarizing studies on the longitudinal clinical and echocardiographic outcomes of surgical repair for primary mitral regurgitation.

I

Intervention

Surgical mitral valve repair (including conventional and minimally invasive/robotic approaches)

Surgical mitral valve repair provides durable long-term outcomes for degenerative MR, though there is a critical need for routine echocardiographic follow-up and robust RCTs comparing novel techniques.

Limitations

Predominantly based on observational studies which cannot exclude selection bias
Lack of robust randomized controlled trials comparing longitudinal outcomes of different techniques
Heterogenous surgical practices and lack of routine postoperative echocardiographic surveillance in asymptomatic patients
Observational nature of existing studies introduces selection bias
Lack of longitudinal objective echocardiographic assessments
Scarcity of robust RCTs comparing conventional vs minimally invasive approaches

Answers are grounded in this paper and cite their sources.

Implication

Supports mitral repair durability in degenerative MR; leaves open optimal surveillance protocols and RCT validation of techniques.

Abstract

Degenerative mitral valve (MV) disease is the most common cause of organic mitral regurgitation (MR) in developed countries. Surgical mitral valve repair is the gold standard treatment for primary MR. Surgical mitral valve repair is associated with excellent outcomes in terms of survival and freedom from recurrent MR. As well, innovations in surgical repair techniques, including thoracoscopically and robotically assisted approaches, further reduce morbidity. Emerging catheter-based therapies may also provide advantages in select patient groups. Although the outcomes following surgical mitral valve repair are well described in the literature, longitudinal follow-up is heterogenous. Indeed, longitudinal follow-up and long-term data are vital to better advise treatment and counsel patients.

Qiu et al. (2023) conducted a review in Primary mitral regurgitation / Degenerative mitral valve disease. Surgical mitral valve repair was evaluated. Surgical mitral valve repair provides excellent long-term survival and low reoperation rates across various pathologies, though longitudinal echocardiographic surveillance is heterogeneously performed and frequently lacking.
