Background: Right ventricular endomyocardial biopsy may cause conduction disturbances, particularly complete right bundle branch block (CRBBB); however, the impact of using the venous access site remains unclear.
Methods and Results: In 274 patients, CRBBB occurred more frequently with the transfemoral than with the transjugular approach (29.2% vs. 6.7%, P<0.001). The transjugular approach independently reduced CRBBB risk (odds ratio 0.17, P<0.001). Sustained CRBBB was also less frequent (8.3% vs. 1.1%, P=0.007). Major complications, including stroke, pacemaker implantation, and death, were absent.
Conclusions: The transjugular approach reduces CRBBB risk and is a safer option for patients at risk of complete atrioventricular block.
