Cardiac hemangioma: a report of two cases and review of the literature

Abstract

Cardiac hemangioma is extremely rare. We encountered two patients with cardiac hemangioma detected by thoracic echocardiography during a medical checkup. In the first case, transthoracic echocardiography revealed a pedunculated tumor in the left ventricle. Selective left coronary angiography demonstrated that the main feeding artery of the tumor arose from the third diagonal branch of the left anterior descending coronary artery. In the second case, thoracic and transesophageal echocardiography showed an oval tumor arising from the right atrium. Both tumors were successfully resected. Histopathological examination revealed that one of the tumors was a capillary hemangioma and the other was a mixed capillary and cavernous hemangioma. After operation, both patients had an uneventful recovery without any complications.

Hemangioma of the Interatrial Septum: CT and MRI Features

“…Differentiation from malignant tumors, which mainly appear in the right atrium, is very important [6]. In our case the tumor was attached to the interatrial septum, a common location for myxoma [7].…”

“…The left atrium is the predominant location for cardiac tumors (72%) [6]. However, according to a review of 56 cases, only 7% of cardiac hemangiomas occur in that chamber, whereas the majority of cardiac hemangiomas tend to arise from the right ventricle (36%), left ventricle (34%), and right atrium (23%) [7]. Differentiation from malignant tumors, which mainly appear in the right atrium, is very important [6].…”

A case report of primary cardiac capillary hemangioma

“…Kojima et al 2 evaluated 56 patients with cardiac hemangiomas, and most frequently observed these tumors in the cardiac ventricle (right ventricle, 35 %; left ventricle, 34 %), followed in order by the right atrium (23 %), interatrial septum (11 %), interventricular septum (11 %), and left atrium (7 %). Different clinical symptoms such as chest congestion, polypnea, cardiac failure, pericardial effusion, and arrhythmia were occurred due to the different sites results in cardiac hemangiomas.…”

A Giant Cavernous Hemangioma of the Heart

“…По данным литературы единое мнение по первой дате описания гемангиомы сердца отсутствует, но прео-бладающее большинство клиницистов считают, что это произошло в 1893г [5][6][7][8]. В последующем, вплоть до настоящего времени, в отечественных и преимуще-ственно зарубежных работах излагаются, как правило, единичные наблюдения по рассматриваемой патоло-гии.…”

“…Среди морфологического многообразия послед-них гемангиомы сердца встречаются чрезвычайно редко. Их частота составляет только 0,45-2,8% всех первичных опухолей сердца [2][3][4][5][6]. В нашем Центре за период с декабря 1962г по декабрь 2014г были выпол-нены хирургические вмешательства 283 больным с новообразованиями сердца, 263 (92,9%) из которых страдали морфологически верифицированными добро-качественными и 20 (7,1%) -злокачественными опухо-лями.…”
