During left ventriculography in a 46-year-old man with hypertrophic cardiomyopathy, we injected 20 ml of contrast material, using a power injector at a rate of 10 ml per second through a multipurpose catheter (MPA2). The left ventricle became opacified, and ventricular tachycardia subsequently developed, for which the patient underwent successful cardioversion. Initially, the catheter was free-floating. During the next beat, it was pulled in, resulting in cannulation. Contrast material was injected into what appeared to be thebesian veins (black arrows), with prompt visualization of cardiac veins (arrowheads) and the coronary sinus (white arrow). No persistent staining of the myocardium was . . . [Full Text of this Article] |
