Key result
Asymptomatic severe MR in MVP may be linked to sudden cardiac arrest or death.
Why the study?
Mitral valve prolapse with asymptomatic severe mitral regurgitation may increase risk of sudden cardiac arrest, but identifying at-risk patients is challenging.
Case Report
Highlights the need to identify patients with asymptomatic severe mitral regurgitation due to mitral valve prolapse who may be at increased risk of sudden cardiac arrest.
The aetiology of sudden cardiac arrest can often be identified to underlying cardiac pathology. Mitral valve prolapse is a relatively common valvular pathology with symptoms manifesting with increasing severity of mitral regurgitation (MR). It is unusual for severe MR to be present without symptoms, and there is growing evidence that this subset of patients may be at increased risk of sudden cardiac arrest or death. The difficulty lies in identifying those patients at risk and applying measures that are appropriate to halting progression to cardiac arrest. This article examines the association of mitral valve prolapse with cardiac arrests, the underlying pathophysiological process and the strategies for identifying those at risk.

Ahmed et al. (2016) conducted a case report in Sudden cardiac arrest and mitral valve prolapse. Mitral valve prolapse was evaluated on Sudden cardiac arrest or death. Mitral valve prolapse with severe asymptomatic mitral regurgitation may be associated with an increased risk of sudden cardiac arrest or death.
