Implantation of transvenous permanent pacemaker in a patient with persistent left superior vena cava and absent right superior vena cava.

Alemzadeh-Ansari MJ, Shafiee A, Yaminisharif A - Int Cardiovasc Res J (2013)

Bottom Line: Vascular access has remained a major challenge for implantation of permanent pacemaker leads.A persistent Left Superior Vena Cava (LSVC), especially with an absent Right Superior Vena Cava (RSVC), is a rare finding during pacemaker implantation and is accompanied by technical difficulties.The patient had a persistent LSVC with an absent RSVC.

ABSTRACT
Vascular access has remained a major challenge for implantation of permanent pacemaker leads. A persistent Left Superior Vena Cava (LSVC), especially with an absent Right Superior Vena Cava (RSVC), is a rare finding during pacemaker implantation and is accompanied by technical difficulties. Herein, we describe a case of sinoatrial node arrest, in which finding a suitable vein for passing the lead was challenging. The patient had a persistent LSVC with an absent RSVC.

fig8301: The Surface 1-Leads Electrocardiogram Revealed Sinus Pause with Junctional Escape Beat. Morphology of QRS Wave Was Left Bundle Branch Block.

Mentions: The blood pressure at presentation was 120 / 50 mmHg, while the pulse rate was 40 beats per minute. The surface 12-lead Electrocardiogram (ECG) revealed a sinus P wave rate of 60 / min, but a sinus pause up to 3000 milliseconds (ms) with junctional escape beat was also observed (Figure 1). The morphology of QRS wave was left bundle branch block. After stopping the use of digoxin and carvedilol for 72 hours, a 24-hour Holter ECG monitoring was requested which revealed frequent episodes of sinus pauses of up to 3500 ms. In the pre-implantation echocardiography, LV ejection fraction was 40%. Therefore, we decided to implant a dual-chamber permanent pacemaker (DDDR mode) for the patient.
