Myocardial infarction with acute valvular regurgitation.

Left-sided valvular lesions are commonly associated with acute and chronic coronary syndromes. Ischemic mitral regurgitation is well described in the literature. We report a case of acute ischemic right-sided valvular disease in which the presenting symptom of an infarction was severe tricuspid regurgitation. This rare entity is usually caused by distortion of the valve apparatus due to underlying wall motion abnormalities. In conclusion, tricuspid regurgitation is an important yet uncommon presentation of acute ischemia that requires a high degree of suspicion for diagnosis.
