Prognostic Stratification?
• 45 yo female Triathlete
• Palpitations, No Family Hx of SCD
• Bileaflet MVP
• Mild to Moderate MR
• Complex VAs, 2 Morphologies
• No LV Fibrosis, mild MAD
Common valvular abnormality
2-3% of general population.
Associated with
arrhythmias in 1/3 of pts
Myxomatous degeneration of
mitral leaflets

MVP as a cause of Sudden Cardiac Death
42 Resuscitated patients with SCA
in whom MVP was the only
detectable cause.

Ok Doctor, but…
Can I do something
to reduce the risk?
Can I do something to reduce the risk?
Beta-Blockers:
- May Reduce Symptoms and
Arrhythmias in some patients
- No Randomized trials on
Outcome
- Doping in some sporting
disciplines
Can I do something to reduce the risk?
Catheter Ablation
Can I do something to reduce the risk?
ICD Implantation:
No specific recommendation
for Mitral valve prolapse.
Usually not indicated in
primary prevention if there is
no LV systolic dysfunction.

Family history of SCD
Disproportionate dilation of the LV(>35mm/m2 in male and >40mm/m2 in female)
High blood pressure

What is the athlete’s perspective?
Hey STOP you have
a Mitral Valve
Prolapse!
No, I must go!
