Key result
Heart transplantation resolves refractory ventricular tachycardia caused by rare cardiac mesenchymal hamartoma.
Why the study?
Cardiac hamartomas are exceedingly rare, histologically benign cardiac tumors with variable clinical presentations.
Case Report (n=1)
No
Cardiac mesenchymal hamartoma is an exceedingly rare cause of refractory ventricular tachycardia that may mimic hypertrophic cardiomyopathy and ultimately require cardiac transplantation when not amenable to surgical resection.
Supports transplantation consideration for unresectable hamartoma-induced refractory VT; leaves open generalizability beyond this single case.
The presentation of a cardiac hamartoma, an exceedingly rare and histologically benign cardiac tumor, can be variable. We describe a case of refractory ventricular tachycardia in a patient with a cardiac mass failing multiple pharmacologic and procedural interventions, ultimately treated by cardiac transplantation and diagnosed with a mesenchymal cardiac hamartoma.

Feng et al. (2020) conducted a case report in Ventricular tachycardia caused by cardiac mesenchymal hamartoma (n=1). Orthotopic heart transplantation was evaluated on Clinical outcome (survival and resolution of ventricular tachycardia). Orthotopic heart transplantation successfully treated a patient with life-threatening, drug-refractory ventricular tachycardia caused by an exceedingly rare cardiac mesenchymal hamartoma.
