Key result
Direct His-bundle pacing was successfully achieved in a patient with a persistent left superior vena cava, leading to an improvement in ejection fraction from 10-15% to 40% and NYHA class IV to II at 3 months.

Demonstrates the feasibility of direct His-bundle pacing in a patient with a persistent left superior vena cava using a steerable sheath and mapping catheter.
May be feasible in persistent left superior vena cava; hypothesis-generating for His-bundle pacing in complex anatomy.
We report a case of direct His-bundle lead placement at the time of implantable cardioverter-defibrillator insertion and atrioventricular node ablation. The patient was found to have an isolated persistent left superior vena cava, and selective His-bundle pacing was successfully achieved through the use of a steerable sheath and dedicated mapping catheter.

Deshmukh et al. (2019) conducted a case report in Nonischemic cardiomyopathy, persistent atrial fibrillation, and persistent left superior vena cava (n=1). Direct His-bundle pacing and AV node ablation was evaluated on Successful lead placement and clinical improvement. Direct His-bundle pacing was successfully achieved in a patient with a persistent left superior vena cava, leading to an improvement in ejection fraction from 10-15% to 40% and NYHA class IV to II at 3 months.
