Successful Treatment of an Infant with Left Ventricular Noncompaction Presenting with Fatal Ventricular Arrhythmia Treated with Cardiac Resynchronization Therapy and an Implantable Cardioverter Defibrillator

الملخص EN

We herein report the successful treatment of a 4-year-old girl with left ventricular noncompaction (LVNC) who presented with incessant ventricular fibrillation at 5 months of age.

An implantable cardioverter defibrillator (ICD) was implanted, and dual chamber (DDD) pacing was initiated at 7 months of age.

At her 10-month follow-up, her left ventricular ejection fraction (LVEF) had decreased from 45% to 20% with mechanical dyssynchrony.

After upgrading to cardiac resynchronization therapy (CRT), the LVEF improved to 50%.

The usefulness of CRT in pediatric LVNC has not been fully elucidated.

However, our case suggests that CRT therapy may be an effective option for LVNC-induced cardiac dysfunction.
