Familial Atrial Myxoma: Three Related Cases at an Australian Tertiary Institution

Abstract

Carney complex accounts for up to two-thirds of familial cardiac myxoma. It is a rare autosomal dominant syndrome, which is also characterized by multiple mucocutaneous lesions and endocrine tumors. We report on three first-degree relatives who underwent surgical resection at the same Australian tertiary institution. One patient re-presented with a recurrent tumor at an interval of 6 years. In this context, the role of interval surveillance, family screening, and genetic testing is explored. We recommend interval echocardiographic surveillance for affected individuals and first-degree relatives given the high risk of recurrence and the morbidity and mortality associated with cardiac tumors in any location.
