Conservative management addresses large infant LV fibroma after cardiac arrest given severe neurological injury.
Case Report (n=1)
Cardiac fibromas, though histologically benign, can cause life-threatening ventricular arrhythmias and require multimodality imaging to assess resectability and guide individualized management.
May support arrhythmia surveillance in fibroma infants; leaves open causal mechanisms and practice change.
BACKGROUND: Cardiac fibromas are benign tumors associated with ventricular arrhythmias. CASE SUMMARY: An 8-month-old infant presented with cardiac arrest due to ventricular tachycardia. Imaging revealed a large infiltrative left ventricular fibroma with severe myocardial involvement. Due to catastrophic hypoxic-ischemic neurological injury and tumor extent, surgical resection and transplantation were not feasible. A conservative approach was adopted. DISCUSSION: Cardiac fibromas may cause life-threatening arrhythmias. Multimodality imaging is essential to assess resectability, and management must be individualized. TAKE-HOME MESSAGES: Cardiac fibromas, although histologically benign, may manifest with life-threatening ventricular arrhythmias. Multimodality imaging is essential for diagnosis and assessment of resectability. Greater myocardial involvement is associated with increased risk of adverse outcomes and should guide clinical management.

Silva et al. (2026) conducted a case report in Cardiac fibroma with ventricular tachycardia (n=1). Conservative management was evaluated. An 8-month-old infant with a large infiltrative left ventricular fibroma presented with cardiac arrest and was managed conservatively due to severe neurological injury and tumor extent.
