Abstract Background: Cardiac cavernous hemangiomas are extremely rare and usually difficult to be diagnosed for being asymptomatic. Case presentation: An asymptomatic 56-year-old woman was hospitalized due to a heart mass found by chest computed tomography (CT) during her annual physical examination. Coronary computed tomography angiography (CTA) disclosed a tumorous lesion, located in the left atrial roof and extended to the posterior wall of the aortic root and surrounding the left main coronary artery. However, there was no communicating branches between the hemangioma and coronary artery and no coronary artery stenosis. The tumor was excised with low-frequency electrocautery under cardiopulmonary bypass. The histopathological examination indicated the mass a cavernous hemangioma. The patient was discharged with an uneventful recovery. Conclusions: Here we presented a rare case of successfully excision of a cavernous hemangioma involving the left atrial roof and left coronary artery. We advocate adequate exposure and complete surgical excision with lowfrequency electrocautery to avoid remnants and excessive resection. Keywords: Cavernous hemangioma, Cardiac benign tumor
Background Cardiac hemangiomas are extremely rare benign vascular tumors of the heart, with an incidence of less than 0.03% at autopsy [1]. Histologically, cardiac hemangiomas can be classified into three categories: capillary, cavernous, and arteriovenous hemangiomas [2]. Of these, cardiac cavernous hemangiomas are exceptionally rare, and seldom involving the left atrial and coronary artery. Surgical excision should be performed as early as possible after diagnosis [3]. To our knowledge, only 3 references of surgically treated left atrial roof cavernous hemangiomas have been reported [4–6]. We reported a cavernous hemangioma located in the left atrial roof and involving the left coronary artery. Case presentation

Preoperative transthoracic echocardiography (TTE) revealed an uneven hyperechoic mass, measuring 81 m × 38 mm, located in the left atrium. The mass attached to the interatrial septum adjacent to the mitral annulus but was not hampering blood flow of mitral valve. Preoperative coronary computed tomography angiography (CTA) showed a relatively low-intensity mass (78 mm × 42 mm) in the left atrial roof and extended to the posterior wall of the aortic root. Coronary CTA revealed no communicating branches between the hemangioma and coronary artery or coronary artery stenosis (Fig. 1). Thus, th
