Key result
Accidental malpositioning of a right ventricular electrode into the left ventricle during CRT implantation was masked by an expected biventricular paced ECG pattern, requiring echocardiography for detection.
Case Report (n=1)
Accidental malplacement of an RV lead into the LV during CRT implantation can mimic normal biventricular pacing on ECG and X-ray, highlighting the importance of early routine echocardiography for detection.
No takes yet. Share an insight, caveat, or question.
May necessitate echocardiography to exclude LV lead malposition in CRT despite normal ECG; leaves open the incidence and optimal detection strategy.
Dißmann et al. (2013) conducted a case report in Dilative cardiomyopathy (n=1). Cardiac resynchronization therapy device implantation was evaluated. Accidental malpositioning of a right ventricular electrode into the left ventricle during CRT implantation was masked by an expected biventricular paced ECG pattern, requiring echocardiography for detection.
