Case report
Unusual Case of Two Synchronous Intracavitary Primary Cardiac Tumors

We report a patient who had two histologic and distinct synchronous intracardiac tumors, with one located in each atrium. The second tumor was missed on intraoperative transesophageal echocardiography, but was discovered when the right atrium was opened using a bi-atrial trans-septal approach. We discuss the merits of this approach and the role of additional imaging for cardiac tumors.

Comment

Primary cardiac neoplasms are uncommon with an incidence of 0.0017% to 0.19% in unselected patients [2]. Atrial myxomas are the most common cardiac neoplasms, accounting for as much as 50% of all benign tumors [3]. Cardiac papillary fibroelastoma is a rare benign neoplasm that mostly involves the endocardial surface of cardiac valves. It almost invariably occurs in adults and is frequently diagnosed at postmortem [4].

Approximately 75% to 88% of atrial myxomas occur in the left atrium [5]. Our

    However, this paper reports a very rare case of a heterogeneous tumor involving two valves. To date, only sporadic similar cases have been reported, and the reported heterogeneous tumors are myxomas and papillary fibroelastomas [1–10]. Agaimy A et al. reported a case of heterogeneous tumors during biopsy, which consisted of a papillary fibroelastoma of the aortic valve and a cystic tumor [11].
