Key result
Single-chamber pacemaker implantation proves feasible and durable in persistent LSVC with absent right SVC.
Why the study?
Persistent left superior vena cava with concomitant agenesis of the right-sided superior vena cava complicates optimal site pacing and lead stability during pacemaker implantation.

Supports feasibility in rare venous anomalies; leaves open generalizability and safety in larger cohorts.
Case Report (n=1)
Demonstrates the feasibility of single-chamber pacemaker implantation in a patient with complex venous anatomy including persistent left superior vena cava and agenesis of the right-sided superior vena cava.
Hassine et al. (2015) conducted a case report in Persistent left superior vena cava and concomitant agenesis of the right-sided superior vena cava (n=1). Single-chamber pacemaker implantation was evaluated on Successful pacemaker implantation and function. Single-chamber pacemaker implantation was successfully performed in a 76-year-old woman with persistent left superior vena cava and agenesis of the right-sided superior vena cava, with good function at 12 months.
