Hybrid right-left cardiac resynchronization therapy defibrillator implantation in persistent left superior vena cava

Area of Science:

• Cardiology
• Anatomical Variations
• Electrophysiology

Background:

• Persistence of the left superior vena cava (PLSVC) is a congenital anomaly occurring in approximately 0.3% of the population.
• This variation presents unique challenges for cardiovascular procedures, especially transvenous lead implantation.
• Accurate identification and management strategies are crucial for successful device implantation.

Observation:

• A patient with PLSVC requiring cardiac resynchronization therapy defibrillator (CRT-D) implantation was encountered.
• Standard transvenous lead placement approaches were deemed unsuitable due to the anomalous venous anatomy.
• A hybrid approach combining right-sided access with left-sided lead placement was considered.

Findings:

• The described hybrid right-left approach for CRT-D implantation in a patient with PLSVC was successfully performed.
• The procedure was found to be both feasible and safe, demonstrating effective lead placement.
• This technique offers a viable alternative to surgical implantation in complex cases.

Implications:

• This hybrid technique provides a valuable alternative for challenging CRT-D implantations in patients with PLSVC.
• It may reduce the need for cardiac surgical intervention, potentially lowering procedural risks and costs.
• Further investigation into this approach could refine treatment strategies for patients with complex venous anomalies.
