Congenital Left Ventricular Diverticulum Complicated by Ventricular Fibrillation

Area of Science:

• Cardiology
• Congenital Heart Disease
• Cardiac Surgery

Background:

• Congenital left ventricular diverticulum (CLVD) is a rare anomaly.
• CLVD can lead to severe adverse events, including sudden cardiac death.

Observation:

• A previously healthy 20-year-old male presented with sudden ventricular fibrillation (VF).
• Intractable VF required cardiopulmonary resuscitation and venoarterial extracorporeal membrane oxygenation (ECMO) for circulatory support.

Findings:

• Cardiac MRI confirmed CLVD in the left ventricle's posterolateral wall.
• The patient had a history of sudden cardiac arrest due to VF.

Implications:

• Surgical repair of CLVD is crucial to prevent recurrent VF and left ventricular rupture.
• Implantable cardioverter-defibrillator (ICD) implantation provides long-term protection against life-threatening arrhythmias.
