Cubital vein access provides a practical alternative to internal jugular vein access for coronary sinus catheter placement

Abstract

AbstractBackgroundInsertion of electrode catheters into the coronary sinus (CS) through the right internal jugular vein (RIJV) carries risks of pneumothorax and severe hematoma formation. This study was performed to compare the safety and feasibility of catheterization through the left cubital superficial vein versus the RIJV.MethodsThis prospective nonrandomized study involved consecutive patients who underwent catheter ablation from September 2021 to February 2023. Blind puncture techniques were used in the left cubital vein group; ultrasound‐guided insertion was performed in the RIJV group. The success rates of sheath insertion and CS catheterization, the procedure and fluoroscopy times of CS cannulation, and complications were compared between groups.ResultsThe left cubital vein group comprised 152 patients, and the RIJV group comprised 58 patients. The sheath insertion success rate was significantly lower in the cubital vein group than in the RIJV group (84.9% vs 100%, respectively; p = .0008). In the cubital vein group, blind puncture attempts failed in 20 patients; three patients developed guidewire‐induced venous injury. One arterial puncture occurred in the RIJV group. After successful sheath insertion, no significant differences were observed in the CS cannulation success rate (97% vs 100%, p = .55), procedure time (median [range], 93 [51–174] vs 74 [44–129] s; p = .19), or fluoroscopy time (median [range], 66 [36–134] vs 48 [30–92] s; p = .17). No serious complications requiring procedural discontinuation occurred.ConclusionThe left cubital vein approach is practical, offering a viable alternative to the RIJV approach.
