Transbrachial retrograde left heart catheterization

Three incidents of asymptomatic arterial thromboembolism associated with polyurethane pigtail catheters occurred during 1,417 cases of left ventricular angiocardiography. No similar incident occurred with polyethylene pigtail or (dacron) Eppendorf and Gensini (style) catheters. In vitro comparison of hydraulic characteristics of polyurethane (Cordis) and polyethylene (Cook) pigtail catheters showed higher flow-pressure transmission through the tip of the Cordis polyurethane catheter favoring dislodgment of any existing clot. The problem of thrombogencity of polyethylene compared with polyurethane remains unsettled. Our experience with polyurethane pigtail catheters has resulted in limitation of their use in our laboratory.

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.

In 19 consecutive children with aortic valve stenosis, the left ventricle was entered retrogradely with a Gensini catheter guided by a tip-deflector guidewire which could produce any desirable degree of curvature at its tip. In all patients, the aortic valve was retrogradely traversed for measurement of the pressure gradient (mean gradient = 53 mmHg, mean valve area = 0.36 cm2), and left ventriculography. No complications were encountered. This technique is safe, simple, and effective in retrograde catheterization of the left ventricle in children with aortic stenosis.
