Key result
Transcatheter arterial embolization achieves tumor regression and symptom resolution without compromising cardiac function.
Why the study?
Cardiac hamartomas are rare benign tumors that pose diagnostic and therapeutic challenges, especially when surgical resection risks compromising cardiac function.
Case Report (n=1)
No
Transcatheter arterial embolization can be an effective, minimally invasive alternative to surgery for controlling the growth of benign cardiac hamartomas and preserving heart function.
May support embolization for symptomatic unresectable cardiac hamartomas; single-case evidence leaves open need for prospective validation.
Cardiac hamartomas are rare benign tumors of disorganized native cardiac tissue that can cause obstruction, arrhythmias, or heart failure, despite their nonmetastatic nature. A 43-year-old woman with intermittent chest tightness and dyspnea underwent imaging suggestive of a malignant cardiac tumor. Intraoperative findings revealed a left ventricular basal inferoseptal hamartoma. Complete surgical resection was deemed too risky due to its location. Instead, transcatheter arterial embolization was performed to reduce the tumor's blood supply, and follow-up imaging showed regression. After ruling out malignancy, balancing the benefits of full surgical removal against the potential impact on cardiac function is crucial. In selected benign cases, transcatheter arterial embolization can be an effective, minimally invasive approach to control tumor growth and preserve heart function.

Chen et al. (2025) conducted a case report in Left ventricular mesenchymal hamartoma (n=1). Transcatheter arterial embolization was evaluated on Tumor regression and symptom resolution. Transcatheter arterial embolization successfully reduced tumor blood supply and resulted in tumor regression and symptom resolution without compromising cardiac function.
