Incidental Discovery of an Atypical Cardiac Tumor

Primary cardiac tumors are rare, present in roughly 0.05% of the population. Cardiac papillary fibroelastoma (CPF) is the second most common, accounting for 10% of primary cardiac tumors.[1] Most cases of CPFs are discovered incidentally on autopsy; however, they may present clinically with systemic embolization or heart failure symptoms. The recommended treatment for symptomatic CPF patients is surgical resection.[1] Treatment in asymptomatic patients remains somewhat controversial with incidentally discovered tumors presenting a clinical dilemma. We present a case of an atypically located CPF that was discovered incidentally on intraoperative transesophageal echocardiography (TEE) during a routine coronary artery bypass graft operation. This case highlights several important points for cardiac anesthesiologists. The first is the importance of performing a comprehensive intraoperative TEE. Next, this case reinforces the broad utility of TEE for evaluation of intracardiac tumors. Finally, this case demonstrates the importance of precise localization of intracardiac tumors.
