A safe, rapid method of transfemoral retrograde left ventricular catheterization in valvular aortic stenosis.

Abstract

We report our experience with the use of a standard left Amplatz coronary catheter and a guidewire to cross the aortic valve in 34 patients being evaluated for valvular aortic stenosis. A number of 2 Amplatz left coronary catheter inserted via the femoral artery was positioned above the noncoronary aortic valve cusp with the tip aligned toward the aortic valve. This catheter allowed a soft-tipped, Teflon-coated guidewire to be guided through the aortic valve orifice. The catheter was then advanced over the guidewire into the left ventricle. This technique was successful within six minutes in 32 of 34 patients (94%). The stenotic aortic valve was crossed in less than two minutes in 15 patients (42%) and in less than four minutes in 31 (91%). The aortic valve was not crossed in two patients. Twenty-one patients (62%) had an aortic valve area of less than 0.75 cm2. There were no complications. We conclude that this technique provides a method for safe, rapid transaortic left ventricular catheterization in patients with aortic stenosis of all degrees of severity.
