  • Title: [Myxoma of the right atrium. Apropos of 10 surgically treated cases].
    Author: Loire R, Delaye J.
    Journal: Ann Cardiol Angeiol (Paris); 1992 Apr; 41(4):177-83. PubMed ID: 1642433.
    Abstract:
    In a series of 100 patients with intracardiac myxoma, the lesion was in the right atrium in 10 cases. The authors attempt to define the particular features of right atrial myxoma in terms of clinical aspects, outcome and pathology. The diagnostic difficulty raised by complex clinical pictures (including right ventricular failure, pseudopericardial forms and forms with a predominance of systemic problems) has now been resolved by imaging and, above all echocardiography. Consequences for the right side of the heart may involve the pulmonary artery with myxomatous emboli causing multiple fusiform aneurysms and pulmonary hypertension, or, more rarely, the tricuspid (with need for valve replacement), vena cava (Budd-Chiari syndrome) or atrial septum (right/left shunt). Alongside systemic problems due to interleukin 6, erythrocyte abnormalities are a new feature. Frequent etiological inclusion in a Carney complex explains recurrences and multi-cavity forms. The dominant pathological feature is tumor calcifications, no doubt as a result of the long presymptomatic phase of myxoma.
