Lobulated Hemangioma as a Rare Cause of Tricuspid Regurgitation.

Introduction: Cardiac hemangioma is one of the rarest tumors, with only a few cases described. Unlike other cardiac tumors, its symptoms are nonspecific, making misdiagnosis easy. Cardiac hemangioma can present with various clinical manifestations, including valve disorder, arrhythmia, pericardial effusion, and embolism. Echocardiography is the most direct examination, and surgical resection the simplest and most effective treatment.

Patients and methods: We present a new case of lobulated cardiac hemangioma causing tricuspid regurgitation and discuss the clinical features, diagnosis, and treatment of this rare tumor.

Results: After surgical resection and tricuspid valve replacement, the patient recovered well.

Conclusion: For cardiac hemangiomas involving the tricuspid valve, tumor resection combined with valve surgery is an effective treatment option.
