Cardiac Hemangioma of the Left Atrial Appendag: A Case Report and Discussion

Abstract

Cardiac hemangioma is an extremely rare, benign vascular tumor of the heart. In contrast to myxoma, hemangioma rarely involves left atrial tissue in adults and little information about the tumor is available. We encountered a 65-year-old woman with a left atrial hemangioma arising in the appendage and growing like an extracardiac mass. The tumor was removed from the left atrium with all the left appendage under cardiopulmonary bypass. Histopathological examination revealed that it was a cavernous-type hemangioma. Among the five described cases, this case was the only one in which the tumor arose from the appendage and grew into the pericardial cavity with resultant paroxystic atrial fibrillation.

Left Atrial Appendage Lipoma: An Unusual Location of Cardiac Lipomas

“…Cardiac hemangiomas rarely involves the left atrium and has been described in the LAA in few cases. 5 In few other cases, inverted LAA was described as a mass mimicking a left atrial tumor or thrombus. 6 Cardiac magnetic resonance imaging (MRI) is important to well delineate and characterize cardiac tissue and masses.…”

Giant cavernous hemangioma of the left atrial appendage: a case description and literature review

“…However, most CHs are in the ventricle, especially in the lateral wall of the LV (6). A CH rooted in the left atrial appendage is particularly rare, and only several cases have been identified in previous studies (Table 1) (7)(8)(9)(10)(11)(12)(13)(14). As a result, our case can be added to this body of literature.…”

Sudden death due to primary atrial neoplasms: Report of two cases and review of literature

“…At autopsy, the frequency of primary cardiac tumours is estimated to be between 0.001 and 0.030% [1,2]. Among these, about 75% are benign, mainly myxomas.…”
