Inadvertent temporary transvenous pacing of the left ventricle: an underreported complication-a case report.

ABSTRACT:

Background

Inadvertent temporary transvenous pacing (TTVP) of left ventricle (LV) is rare and likely underreported, posing significant embolic risk. We present a case of TTVP with atypical trajectory identified on computed tomography (CT) imaging.

Summary

A 62-year-old male with metastatic renal cell carcinoma on chemotherapy and bifascicular block presented with symptomatic bradycardia and non-ST-elevation myocardial infarction (NSTEMI), raising concerns for complete heart block on ECG. Intermittent asystole occurred during TTVP placement with appropriate capture. Post-procedure, ECG showed ventricular-paced rhythm with pseudo-right bundle branch block, and chest X-ray suggested lead placement in right ventricle; however, suboptimal echocardiography limited lead visualizati
