[Acute pulmonary edema with normal coronary arteries: mechanism identification by ergonovine stress echocardiography].
Coronary spasm is a constriction of the epicardial coronary arteries that produces myocardial ischemia. It is considered the main mechanism of the dynamic coronary artery stenosis. The standard method for diagnosing coronary spasm is the ergonovine test during diagnostic coronary angiography. Another test currently used is stress echocardiography with intravenous ergonovine injection. We present the case of a patient with angina, acute pulmonary edema and normal angiographic coronary arteries in which stress echocardiography with ergonovine demonstrated transient severe mitral regurgitation.
