Non-Capture of Discreet Left Ventricular Lead Advancing Advanced Heart Failure
Keywords:
Cardiac resynchronization, cardiac resynchronization therapy (CRT), Systolic heart failure, Lead positioning, Advanced heart failureAbstract
This case report illustrates a challenging case of worsening heart failure in a previously well-compensated patient with unclear etiology. Further workup revealed the patient’s cardiac resynchronization therapy-defibrillator (CRT-D) left ventricle (LV) lead was losing capture during positional changes. This case demonstrates the importance of device optimization, as well as electrocardiogram (ECG) monitoring to elucidate possible causes of acute systolic heart failure.
