Irreversible myocardial damage after coronary air embolism--a case report.

This case report describes the complication of an air embolism in the right coronary artery that developed during coronary angiography in a patient with acute anterior myocardial infarction. Follow-up left ventriculography, 4 months later, showed irreversible inferior wall damage. Incomplete aspiration of the angiographic catheter was the cause of this complication and should be avoided.
