Hemangiomas are rare benign tumours of the heart, generally asymptomatic and usually diagnosed in male young or full-grown adults. We report here a case of a symptomatic right atrial hemangioma in a 75-year-old woman with a clinical history of hypertension. The tumour was diagnosed after an episode of acute bronchopneumonia precipiting the patient's cardiac failure initially referred to the hypertensive condition.

Hemangioma located just above the left main coronary artery, in a subject who had cardiac arrest due to ventricular fibrillation, led to a diagnosis of Brugada syndrome.Int J Cardiol. 2007 Jul 25.

We report the case of a 38-year-old Asian man with a pericardial hemangioma on the left main coronary artery. The patient presented initially at our hospital after cardiopulmonary resuscitation following an episode of ventricular fibrillation (VF). Because of spontaneous coved-type ST segment elevation on the higher intercostal space V1 to V2 in a 12-lead electrocardiogram, documented VF in the absence of structural heart disease, and a family history of sudden death, he was diagnosed with Brugada syndrome. Transesophageal echocardiography showed a smooth-surfaced mass with well-demarcated borders, directly above the left main coronary artery. Computed tomography confirmed the presence of the mass, which showed no enhancement at early phase, but did demonstrate homogenous enhancement at delay phase by contrast material. There were no findings from either the nuclear medicine or the tumor marker investigations which indicated that the mass located just above the main coronary arteries was malignant. Therefore, taken together, these findings suggested that the tumor might be a pericardial hemangioma. The relationship between the location of the hemangioma just above the left main coronary artery and the occurrence of VF was not clear, i.e. whether the presence of the hemangioma caused the stimulation of the left main coronary artery and as a result, led to the spasm of the left main coronary artery and the occurrence of VF. Furthermore, as the tumor did not extend into any of the adjacent structures, such as the coronary arteries or the right ventricular outflow tract, surgical resection was not performed; instead, the patient received a dual chamber implantable cardioverter-defibrillator.

Cardiac hemangioma complicated with cerebral and coronary embolization.Heart Vessels. 2005 Nov;20(6):296-7.

Cardiac hemangiomas are rare, benign vascular tumors of the heart. Because of their clinical manifestations, diagnosis is difficult and few surgeons can draw from extensive experience. The purpose of this study was to report an additional case of cardiac hemangioma and to analyze the unexpected aspect of this disease. In our case, echocardiography demonstrated a mass in the left ventricle. Surgical resection was done using cardiopulmonary bypass. Histopathological examination revealed that the tumor was a hemangioma. The short-term outcome was favorable.
