This systematic review examines the relationship between mitral annular disjunction (MAD) and arrhythmic risk in patients with degenerative mitral regurgitation. It highlights that extensive MAD (≥ 5 mm) and associated features like late gadolinium enhancement are linked to increased arrhythmic vulnerability. The study emphasizes the need for improved risk stratification in surgical approaches to mitigate postoperative arrhythmias.
Key findings
- Extensive MAD (≥ 5 mm) is associated with increased arrhythmic vulnerability.
- Late gadolinium enhancement correlates with higher risk of ventricular arrhythmias.
- Ventricular arrhythmias can occur even after technically successful mitral valve repair.
Why it matters
Understanding the arrhythmic risks associated with MAD is crucial for clinicians to improve patient outcomes post-surgery. Enhanced risk stratification may lead to better management strategies and interventions for patients with degenerative mitral regurgitation.
