Hemangiomas are rare benign tumors of the heart. Clinical presentation is highly variable according to the location, size, and extension of the tumor. Hemangiomas have been described in all cardiac chambers, but most occur on the right side of the heart and in the left atrium. Although diagnosis is typically made by echocardiography, the definite diagnosis can be made with certainty only from a very careful histopathologic examination. The authors report a case of atypically located hemangiomas originating from the left atrial appendage and right atrium in a 71-year-old woman who presented with ischemic stroke. Transthoracic and transesophageal echocardiography demonstrated an elongated left atrial mass originating in the atrial appendage and extending well into the left atrium to the mitral orifice, as well as a right atrial mass and intense biatrial spontaneous echo contrast. It was unclear whether the masses represented thrombus or an unusually located atrial tumor. Immunohistologic examinations revealed a biatrial cavernous hemangioma with no signs of malignancy.

    ABSTRACT: We report an adolescent with a benign cardiac haemangioma with attachments exclusively to the anterior leaflet of the mitral valve. On the basis of our review of the literature, this study has not been reported previously.

    ABSTRACT: Uterine leiomyomatosis is a common disease in women; however, intravenous leiomyomatosis with intracaval and intracardiac tumor extension is rare. We sought to analyze the clinical and echocardiographic features of intracardiac leiomyomatosis. From January 2003 through July 2012, 7 women (age range, 24-59 yr) underwent surgical resection of histopathologically diagnosed intracardiac leiomyomas at our hospital. Most of the patients had histories of hysterectomy or uterine leiomyoma. We retrospectively analyzed their preoperative echocardiograms. We found that the tumors had no stalks, did not adhere to the wall of the right side of the heart, were highly mobile, and moved back and forth in the right atrium near the tricuspid orifice. All tumors originated from the inferior vena cava and had borders well demarcated from that structure's wall. Most of the masses extended into the inferior vena cava and right atrium through the right internal and common iliac veins. Computed tomograms revealed pelvic tumors and contiguous filling defects in 6 patients. When echocardiograms reveal a right-sided cardiac mass that originates from the inferior vena cava, particularly in women who have a history of hysterectomy or uterine leiomyoma, intracardiac leiomyomatosis should be suspected. If the mass has no stalk and freely moves within the inferior vena cava and right-sided cardiac chambers without attachment to the endothelial surface or endocardium, intracardiac leiomyomatosis should be diagnosed. We discuss our findings and briefly review the relevant medical literature.

    ABSTRACT: Cardiac hemangioma is a rare clinical entity. An increasing number of cases have been reported in recent years. Most of them were found incidentally at autopsy or during clinical practice, and reported as isolated cases. Our study is the most comprehensive review of cardiac hemangioma to date. The clinical demographics, clinical features, histopathologic features, treatment, and prognosis of 200 cases are reported. Logistic regression analysis was performed to identify the independent predictors of hemangioma-related death and long-term adverse events. We provide a few recommendations for diagnosis and treatment of this uncommon and sometimes lethal disorder. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc.
