Left Heart Catheterization Using the Single Catheter Radial Approach with the Multipurpose Catheter

This technical report described using a single multipurpose catheter via radial artery access to cannulate both coronary arteries during left heart catheterization — a procedural variation intended to reduce the catheter exchanges typically required in the transradial approach.

The multipurpose catheter’s geometry allows it to engage both coronary ostia and the left ventricle without requiring a catheter change. The authors demonstrate feasibility and describe the technique through illustrative cases.

This is procedural documentation at the case-report level, not a clinical outcomes study. Whether single-catheter technique improves patient outcomes, reduces complication rates, or shortens procedure time compared to standard multi-catheter transradial approaches is not addressed. The report contributes to the operator’s technical toolkit but cannot guide evidence-based practice change on its own.

We rate the evidence limited. A narrow technical report documenting procedural feasibility; comparative outcome data would be needed to establish clinical value.
