Abstract:
In a patient with prior myocardial infarction who had complained of frequent angina repeat arteriograms proved normal coronary arteries. Both ECG exercise testing and thallium scanning excluded ischemia. Resting echocardiogram showed increased distal septal and right ventricular apical myocardial echo intensity. Dobutamine stress echo demonstrated right ventricular and posteroseptal abnormalities consistent with ischemia. Repeat angiogram with ergonovine confirmed distal right coronary spasm.
