Coronary angiography with four French catheters

Abstract In coronary angiography, there is a trend to use smaller catheters in order to avoid puncture site complications and minimize hospital stay. 1–4 It is a standard practice in our laboratory to perform routine coronary angiography with 6Fr catheters. Recently, 4Fr catheters have been introduced for angiography. This prospective randomized study addresses the performance of 4Fr catheters for diagnostic coronary angiography compared with 6Fr catheters.
