Mitral valve prolapse is a relatively common cardiac valve disorder that usually has a favorable prognosis. Occasional patients may develop complications, including sudden death, chest pains, transient ischemic attacks and severe mitral valve regurgitation. It may be necessary to disqualify an athlete with mitral valve prolapse if certain findings are identified during the clinical evaluation.


Reasons to disqualify an athlete with mitral valve prolapse:

(1) history of syncope

(2) disabling chest pain

(3) complex ventricular arrhythmias, particularly if these are induced or worsened by exercise

(4) significant mitral regurgitation

(5) prolonged QT interval

(6) presence of Marfan's syndrome

(7) family history of sudden death


Exercise testing with monitoring may be required.
