Real-Time Ultrasound-Guided Venous Access of the Arm for Right Heart Catheterization

Objective. Arterial access from the wrist for cardiac catheterization is increasingly being used. Right heart catheterization (RHC) is an integral part of many of these procedures. Reliable venous access from the arm allows avoidance of femoral or jugular venous access for RHC. It is uncertain if ultrasound guidance offers a benefit for venous access of the arm for RHC. This study sought to assess the efficacy of ultrasound-guided venous access of the arm (UGVAA) for RHC. Methods. A retrospective study was performed on consecutive patients undergoing RHC at a single institution between August 2015 and July 2016. Baseline data, procedural information, and success rates of UGVAA and RHC were assessed. Results. A total of 266 consecutive RHC procedures were identified, of which 253 (95.1%) were performed via arm venous access; of these, a pre-existing intravenous catheter was used in 3 cases, UGVAA was used in 241 cases, and UGVAA was probably used but not documented in 9 cases. There was 100% success of venous cannulation and sheath placement in these 253 patients. RHC via the arm vein was successful in 248 patients (98.0%) and failed in 5 patients (2.0%). Mean procedure time for RHC via arm access was 5.7 minutes. The femoral approach was used in 12 patients (4.5%). A jugular approach was used in 1 patient (0.4%). All patients had concomitant left heart catheterization via transradial access. Conclusions. UGVAA is a highly efficacious and safe technique, with a success rate of 98% for RHC in our consecutive series of 253 patients. UGVAA may allow for near-universal use of arm veins for RHC.
