Heart transplantation for ventricular arrhythmia caused by a rare hamartoma

Area of Science:

• Cardiology
• Cardiac Pathology
• Oncology

Background:

• Cardiac hamartoma is a rare cardiac tumor composed of mature cardiac myocytes.
• It shares histological similarities with hypertrophic cardiomyopathy and rhabdomyomas.
• These tumors can present with complex clinical manifestations.

Observation:

• A patient presented with a ventricular hamartoma.
• The hamartoma complicated the patient's condition with ventricular tachycardia.
• Surgical resection was deemed impractical due to challenges in maintaining ventricular geometry.

Findings:

• The ventricular hamartoma led to life-threatening ventricular tachycardia.
• The complexity of the tumor's location and impact on ventricular geometry precluded safe surgical excision.
• Heart transplantation was ultimately performed as the definitive treatment.

Implications:

• This case highlights the potential for cardiac hamartomas to cause significant arrhythmias.
• It underscores the surgical challenges associated with ventricular hamartomas.
• Heart transplantation may be a necessary therapeutic option for complex cardiac hamartomas unresponsive to other interventions.
