Subsequently, a 6-French angled pigtail catheter was used to measure left ventricular pressures and to perform a power injection, a left ventriculogram at 8 mL per second for a total of 30 mL. At the conclusion of the diagnostic evaluation, the patient had selective arteriography of her right femoral artery, which showed the right femoral artery to be free of significant atherosclerotic plaque.
