Cavernous hemangioma of the mitral valve: a case report and review of literature

Abstract

Cardiac hemangiomas are rare cardiac tumors with fewer than 50 surgically treated cases reported in the literature. Incidence of valvular hemangiomas is extremely low, as cardiac valves are predominantly avascular structures. In this case report, we describe a 33-year-old woman who presented with progressively worsening cardiovascular symptoms. Echocardiography revealed a mitral valve mass for which she underwent surgical resection and mitral valve replacement. Histological examination of the mass revealed cavernous hemangioma of the mitral valve. Postoperative course was uncomplicated, and the patient's symptoms improved after surgery. Surgical excision of valvular hemangiomas appears to be curative in most cases and is the treatment of choice. Periodic echocardiographic follow-up is advised for early detection of tumor recurrence.

Cavernous hemangioma of the mitral valve – a rare heart tumor. А clinical case

“…Опухоль может быть обнаружена в любом возрасте, что в значительной степени определя-ется ее местоположением. Прогноз при гемангио-мах также зависит от локализации и размера опу-холи, примерно в половине случаев их выявляют случайно при аутопсии [10,11].…”

“…Так, в большом обзоре H. McAllister и соавторов из 533 случаев пер-вичных опухолей сердца было только 15 (2,8 %) наблюдений гемангиом [8]. В мировой литера-туре имеется всего около 50 сообщений о хирур-гическом лечении первичных кардиальных гемангиом [11].…”

An Exceptional Cause of Progressive Dyspnoea in a Renal Transplant Recipient: Hemangioma of the Mitral Valve

“…Other reported cases reveal data from a shorter follow up period such as one to two years [9,10], or no data at all [26,40]. No recurrences of cardiac hemangioma have been reported so far, but given the rareness of the condition and hence the uncertain prognosis, regular follow up is probably warranted [3]. …”

“…The presenting symptoms of heart valve hemangiomas may include palpitations and syncope, exertional dyspnea, heart failure due to hemodynamic disturbances, and atypical chest pain. [3,6,9,10,25,26,27]. In addition to these symptoms, the presenting symptoms of a cardiac hemangioma localized elsewhere than on the valves may be arrhythmias [28,29], embolic incidents [30,31,32], sudden cardiac death [33], pericardial effusion [34,35] and heart tamponade [36].…”

“…They can be found in any age group, but occur most commonly in childhood. To our knowledge, less than 10 cases of mitral valve hemangiomas have been documented in the literature [3,4,5,6,7,8,9,10,11]. …”
