Transradial cardiac catheterization in patients with coronary bypass grafts: feasibility analysis and comparison with transfemoral approach.

The objective of this study was to analyze the feasibility and safety of transradial catheterization in patients with remote surgical cardiac revascularization. Selective catheterization of coronary bypass grafts might be more difficult and time-consuming from the radial artery as compared to the femoral route. This special patient subset has been either excluded or underrepresented in previous studies.

Safety and efficacy of a multipurpose coronary angiography strategy using the transradial technique.

Unlabelled: The use of a single catheter for coronary angiography has a number of potential advantages such as the reduction of arterial trauma, costs and procedural time. Accordingly, we assessed the feasibility and safety of two different strategies for transradial multipurpose coronary angiography.

Methods: From February 2002 to December 2004, a total of 657 transradial diagnostic catheterizations were performed by a single operator in which engagement of both left and right coronary arteries was attempted either with a Judkins Left 3.
