Risk factors for sudden cardiac death from arrhythmic mitral valve prolapse (Part 1)

Arrhythmic mitral valve prolapse has been identified as a potential cause of sudden cardiac death among some patients with primary mitral regurgitation. What are critical indications and possible mechanisms? In this discussion, we review:

  • Why patients with mild to moderate mitral regurgitation are at higher risk than those with severe regurgitation
  • Why patients with bileaflet prolapse are at increased risk over those with isolated posterior leaflet mitral valve prolapse
  • Why the complexity of Premature Ventricular Contractions (PVC), rather than the number of PVCs, matters most in assessing risk in patients suffering mitral valve prolapse
  • How changes in the structure of the ventricular myocardium are extremely important in identifying patients at risk for sudden cardiac death
