Key result
Emergency transvenous pacing for complete heart block reveals incidental PLSVC via an unusual lead course.
Why the study?
Patients with persistent left superior vena cava are usually asymptomatic, but anatomical defects commonly cause difficulties in establishing central venous access, pacemaker implantation, and cardiothoracic surgery.
Case Report (n=1)
Highlights the incidental finding of persistent left superior vena cava during transvenous pacing due to an unusual lead course on chest X-ray.
May alert clinicians to PLSVC in atypical pacing lead courses on CXR; case reports leave open systematic screening value.
Patients with persistent left superior vena cava (PLSVC) are usually asymptomatic, but due to its anatomical defects, difficulties in establishing central venous access, pacemaker implantation and cardiothoracic surgery are common. We report a case of 65 years old patient who presented with complete heart block in cardiac critical care and, after emergency transvenous pacing, the chest X-ray showed unusual course of the transvenous pacing lead, which on further transthoracic echocardiographic (TTE) evaluation demonstrated dilated coronary sinus with PLSVC.

Subash et al. (2015) conducted a case report in Complete heart block (n=1). Emergency transvenous pacing was evaluated. Emergency transvenous pacing in a 65-year-old patient with complete heart block revealed an unusual lead course, leading to the incidental diagnosis of persistent left superior vena cava.
