Antecubital vs Femoral Venous Access for Right Heart Catheterization: Benefits of a Flashback.

Background: Although rare, complications of right heart catheterization (RHC) are usually related to the access site. Antecubital venous access for RHC allows immediate ambulation and may reduce access-site complications, but data on this approach are scarce.

Methods: Our study prospectively collected comprehensive data from consecutive RHCs performed at our academic center between February 2010 and August 2013. Demographic, procedural, and in-hospital outcomes were compared between patient groups defined by antecubital and femoral approaches.

Results: A total of 1007 RHC procedures was performed; 895 (88.9%) were performed through an antecubital approach and 112 (11.1%) were performed through a femoral approach. Antecubital attempts were successful in 92.8% of the clinically eligible patients. The antecubital approach was associated with a shorter procedure duration and fluoroscopy time as well as a lower radiation dose (P < 0.001 for all) compared with femoral access. Radiation dose and fluoroscopy time were significantly reduced (P < 0.001 for both) when antecubital procedures were performed by experienced operators compared with trainees. Periprocedural complications occurred in 8 patients (0.8%) (leading to prolonged hospitalization in only 1 patient in the femoral group). Access-site hematoma occurred more frequently in the femoral group (P < 0.001).

Conclusions: An antecubital venous approach is a feasible alternative to femoral venous access for RHC. Shorter fluoroscopy time, lower radiation dose, and fewer access-site hematomas with this approach argue for its preferential use when possible and performed in an experienced centre.
