Left Atrial Myxoma
Abstract
Cardiac myxomas are benign tumors of the heart and arise most commonly from the interatrial septum, typically on the left side. They may grow to be fairly large at presentation, often associated with intracardiac obstruction, embolic events, or constitutional symptoms. Although they are histologically benign, cardiac myxomas by virtue of their location and size can be a source of significant morbidity and mortality. Notably, patients with cardiac myxomas have an increased risk for sudden death and surgical excision is typically recommended. Primary tumors of the heart are rare, but are typically benign when they do occur. Approximately half of benign primary tumors of the heart are cardiac myxomas. Cardiac myxomas may remain clinically occult for many years, resulting in their substantial growth prior to manifesting symptoms. Their large size at presentation and intracavitary location can be associated with significant morbidity and mortality, even sudden death. Cardiac myxomas, therefore, require urgent attention and surgical excision.
