Key result
His-bundle lead implantation was successfully performed to treat pacing-induced cardiomyopathy in a patient with persistent left superior vena cava and absent right superior vena cava.
Why the study?
Persistent left superior vena cava presents technical challenges for transvenous device implantation, and physiologic pacing strategies like His-bundle pacing may avoid or treat pacing-induced cardiomyopathy.
Demonstrates the feasibility of His-bundle lead implantation in a patient with complex venous anatomy (PLSVC and absent right SVC) to treat pacing-induced cardiomyopathy.
Supports feasibility of His-bundle pacing in rare venous anomalies; hypothesis-generating and requires prospective confirmation before clinical adoption.
Persistent left superior vena cava (PLSVC) poses technical challenges to implantation of transvenous cardiac implantable electronic devices. His-bundle pacing is a physiologic pacing strategy to avoid or treat pacing-induced cardiomyopathy. We report a case of His-bundle lead implantation in a patient with PLSVC, absent right SVC, and pacing-induced cardiomyopathy.
