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 coronary artery cineangiography, ventriculography and aortography in 50 of 100 cases. A second, specially shaped, open tip catheter was used in an additional 46 cases, and a third in 4. 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 the patients. Left heart study with these catheters caused minimal arterial trauma, a low incidence of complications and shortened catheterization times.
