Insights
This case report details a rare cardiac hemangioma causing severe heart failure. Surgical removal and a ventricular assist device led to significant patient improvement.
Area of Science:
- Cardiology
- Oncology
- Cardiac Surgery
Background:
- Cardiac hemangiomas are rare, accounting for 5-10% of benign cardiac tumors.
- Large cardiac masses can cause significant hemodynamic compromise and heart failure.
Purpose of the Study:
- To report a rare case of a large cardiac hemangioma causing end-stage heart failure.
- To describe the diagnostic and therapeutic approach for this rare condition.
Main Methods:
- Diagnostic imaging included echocardiography, contrast-enhanced computed tomography, and cardiac magnetic resonance.
- The treatment involved simultaneous tumor resection and left ventricular assist device implantation.
Main Results:
- A large, lobulated right atrial mass measuring 100 x 96.5 x 104 mm was identified.
- Histopathology confirmed the diagnosis of cardiac hemangioma.
- The patient experienced significant clinical improvement and survived for 3 years post-procedure with minor complications.
Conclusions:
- Surgical resection combined with mechanical circulatory support can be effective for large cardiac hemangiomas causing heart failure.
- Early diagnosis and intervention are crucial for managing patients with symptomatic cardiac hemangiomas.
Abstract:
Cardiac hemangiomas are exceedingly rare, comprising only 5% to 10% of benign cardiac tumors. We report a patient with a large right atrial mass and end-stage heart failure with severe left ventricular dysfunction. Echocardiography revealed a mass obstructing tricuspid inflow. Contrast-enhanced computed tomography and cardiac magnetic resonance confirmed a 100 mm × 96.5 mm × 104 mm lobulated mass. Simultaneous tumor resection and left ventricular assist device implantation were performed. Histopathologic examination confirmed a cardiac hemangioma. The patient showed significant improvement and remained alive at 3-year follow-up, with only minor gastrointestinal bleeding episodes.
