A simplified method for performing retrograde left heart catheterization is described which utilizes a family of preshaped catheters via brachial artery cutdown. A single closed-tip catheter was the sole catheter utilized to accomplish complete left heart studies including coronarv artery cineangiography, ventriculography and aortography in 50 or our last 100 cases. A second, specially shaped, open-tip catheter was used in an additional 46 cases, and a third in four. The aortic valve could be crossed readily, and ventriculography was accomplished with a minimum of premature ventricular contractions. Coronary arteriography could be performed safely with a closed-tip catheter in the majority of our patients. Left heart study with these catheters caused minimal arterial trauma, a low incidence of complications, and shortened catheterization times.
