Background and Objectives Cardiac myxoma is the most frequent benign cardiac tumor that can result in cardiac and systemic symptoms. We investigated clinical and echocardiographic characteristics of patients with cardiac masses suggesting myxoma. Methods We investigated 265 consecutive patients with an echocardiographic diagnosis of cardiac myxomas in 4 teaching hospitals in Korea. Results The mean age was 61±16 years and 169 patients (63.8%) were female. The most frequent referral reason for echocardiography was an evaluation of cardiac symptoms (43.4%). Tumors were incidentally detected in 82 patients (30.9%). Left atrium (LA) was the most frequently involved site (84.5%) and 19 patients (7.2%) had non-atrial tumors. The mean tumor size was 38.7×26.0 mm (range, 4–96 mm). Of 186 patients (70.2%) who had pathological diagnosis, 174 (93.5%) were confirmed with myxoma, 8 (4.3%) with other tumors and 4 (2.2%) with thrombi. Compared to myxoma, smaller size (20.4×12.6 mm vs. 41.4×27.6 mm, p<0.01) and non-LA location (87.5% vs. 10.5%, p<0.001) were associated with non-myxoma tumors, and more frequent atrial fibrillation (AF, 75.0% vs. 7.0%, p<0.001) and larger LA diameter (55.0±14.6 mm vs. 41.3±7.7 mm, p=0.001) were related to thrombi. Conclusions Of 265 patients with an echocardiographic diagnosis with cardiac myxomas, 174 (65.7%) were surgically confirmed with myxomas. Compared with cardiac myxoma, other tumors were smaller and more frequently found in non-atrial sites. Thrombi were associated with AF and larger LA diameter.

“…The patient's symptoms were nonspecific and echocardiography findings were not discriminatory. On echocardiography, both myxomas and thrombi appear heterogeneous [9]. Thrombi are often multiple, are of various sizes, and occur in varied locations.…”

Intracardiac masses can be challenging to differentiate by echocardiography. We present a case of several intracardiac masses with echocardiographic features of both thrombi and myxoma in a patient with heart failure symptoms. The masses were confirmed to be thrombi after complete resolution on repeat echocardiography following anticoagulation. Echocardiography complements the history and physical exams in diagnosing intracardiac masses but may present a diagnostic challenge when features are not pathognomonic. Follow up imaging after anticoagulation should be standard of care to avoid unnecessary surgeries when the diagnosis of a cardiac mass is uncertain.

“…and thrombi appear heterogeneous. 3 Myxomas may be pedunculated or sessile and exhibit intralesional hemorrhage, degeneration, or calcification, which can present as central hypo or hyperechogenicity, and may help identify it. 4,5 However, chronic thrombi can exhibit these same features.…”

“…The primary site of interest is the left atrial appendage, in which over 91% of atrial fibrillation‐related thrombi are formed 2 . On echocardiography, both myxomas and thrombi appear heterogeneous 3 . Myxomas may be pedunculated or sessile and exhibit intralesional hemorrhage, degeneration, or calcification, which can present as central hypo or hyperechogenicity, and may help identify it 4,5 .…”
