Summary
Conductor externalization caused left-ventricular lead failure. Left bundle branch area pacing (LBBAP) offered a successful physiological alternative when coronary-sinus lead reimplantation was not possible.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Transvenous lead failure due to conductor externalization is a known issue.
- Left-ventricular (LV) coronary-sinus (CS) lead failure requiring extraction is uncommon.
- Conduction system pacing, specifically left bundle branch area pacing (LBBAP), presents a physiological alternative for patients when CS lead reimplantation is not feasible.

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
