Coronary stenting using a 6 F. diagnostic catheter: a report of two cases

Abstract

Standard guiding catheters for coronary interventions may not selectively engage the coronary ostium despite a successful cannulation with a diagnostic catheter of the same curve. This discrepancy is explained by a slight difference in shape between the two catheters (shorter tip of the guiding, absence of tip tapering, etc.). The authors report on the use of 6 F. coronary diagnostic catheters as guiding catheters for coronary angioplasty and stent implantation in two patients with critical stenoses: in the right coronary artery distal to a right internal mammary artery anastomosis in one and in the ostial right coronary artery in the other. In both cases, the use of diagnostic catheters was the key to success despite the vessel orifice being unfavourable for the use of different types of guiding catheters.
