Primary Cardiac Sarcoma Involving the Mitral Valve, an Insidious Form of Heart Failure

A cardiac intimal sarcoma mimicking infective endocarditis

Primary malignant cardiac tumors are rare and usually misdiagnosed because they can mimic more common intracardiac lesions, therefore, in clinical practice it is important to always consider even uncommon diseases in order to avoid delayed diagnosis and to plan the most appropriate therapeutic strategy in a timely fashion. We report a case of a 73-year-old man with clinical signs and imaging findings (echocardiography) suggesting infective bacterial endocarditis of the mitral valve. However, intraoperative evaluation raised suspicion that the mitral lesions had a different nature. Surgical removal of the mass was performed, and the final correct diagnosis was made through pathologic examination, revealing a mitral valve sarcoma thus allowing for the beginning of specific oncological treatment.

Primary mitral valve angiosarcoma: A multifaced ultra-rare tumor

Malignant primary cardiac valve tumors are extremely rare neoplasms usually remaining silent up to late advanced stages. Getting to know the various features of this latent tumor, which needs prompt intervention, can assist in the earlier diagnosis. Herein we report a 24-year-old woman with angiosarcoma that originated from the mitral valve and manifested itself through dyspnea and pulmonary edema. The case is noteworthy with respect to appealing echocardiographic images.
