Abstract
In a patient with moderate valvular aortic stenosis transient myocardial injury resulted from extravasation of contrast material into the posterolateral wall of the left ventricle during selective left ventricular cineangiocardiography via the transseptal approach. The patient developed anterior upper chest pain, runs of idioventricular rhythm followed by spontaneous return to sinus rhythm with elevated ST segments, and increase in serum transaminase levels. Lack of previous reports of transient myocardial damage secondary to extravasation of contrast material, increased possibility of such accidents with increased use of selective left ventricular angiocardiography, and possible preventive methods were emphasized.
