Noncomplicated Excision of a Mobile Pedunculated Septal Hemangioma of the Left Ventricle

Abstract

Patient: Female, 27Final Diagnosis: LV hemangiomaSymptoms: Palpitation • dyspnea • fatigueMedication: —Clinical Procedure: Posterior atriotomySpecialty: CardiologyObjective:Rare diseaseBackground:Cardiac tumors are quite rare, and differential diagnosis of them is challenging.Case Report:A young lady with a history of palpitations, dyspnea, and fatigue was proven by transthoracic echocardiography and cardiac magnetic resonance imaging to have a mobile left ventricular mass with rounded contour attached to the mid-part of the interventricular septum. The mass was approached via a posterior inter-atrial approach to avoid left ventriculotomy and provide adequate exposure to completely excise the tumor and control its pedicle with minimal cardiac trauma. Histological examination of the mass was diagnostic of capillary and sinusoidal hemangioma.Conclusions:Complete excision of cardiac hemangioma is recommended once it is diagnosed, for histopathologic diagnosis and because of the possibility of serious complications.

A giant, well‐differentiated papillary mesothelioma of the left atrioventricular groove: Case report and brief review of the literature

“…They are most frequently observed in the left ventricle, followed by the right atrium, right ventricle, and left atrium . Hemangiomas may arise from any cardiac layer—endocardium, myocardium, or epicardium—but they usually originate from the myocardium . Echocardiography typically shows a mass of homogeneous echogenicity with clear borders.…”

Cardiac papillary muscle hemangioma

“…[1][2][3] Cardiac hemangiomas are benign vascular tumors originating from the proliferation of endothelial cells of the blood vessels. 1,4 They are quite rare and account for 5-10% of benign cardiac tumors. 2 They may present at any age, and there is a slight male preponderance.…”

“…5 Most cardiac hemangiomas are asymptomatic and discovered incidentally on echocardiography, computed tomography (CT), cardiac magnetic resonance image (MRI), or at autopsy. In symptomatic patients, a cardiac hemangioma may lead to dyspnea, arrhythmias, heart failure, pericarditis, pericardial effusion, systemic embolism, 1,4,6 and the patients may have associated vascular syndromes, such as Kasabach-Merritt syndrome. 1 While the cardiac hemangioma may be found in any cardiac layer and any chamber, the most frequent locations are the lateral wall of the right ventricle, the anterior wall of the right ventricle, interventricular septum and, occasionally, the right ventricular outflow tract.…”
