[Mitral valve prolapse and myocardial ischemia. Apropos of 2 cases]

The authors report two cases of severe myocardial ischaemia with healthy coronary arteries associated with mitral valvular prolapse (MVP). The first case was a 43-year-old woman treated with beta-blockers following the discovery of MVP. This patient was admitted to hospital six months later with persistent chest pain in a context of cardiogenic shock. The response to treatment was rapid and spectacular. The second case was a 44-year-old hypertensive smoker man in whom assessment of chest pain revealed several signs of myocardial infarction as well as MVP. This rare combination of MVP and myocardial ischaemia raises pathophysiological as well as therapeutic problems.
