Introduction
Cardiac myxoma(CM) is a rare cardiac disease with an overall incidence of about 0.5-1.0/million/y[1]. CM accounts for approximately 70% of the adult cardiac tumors, with the majority (75%) located in the left atrium and less commonly in the right atrium (20%)[2]. Rarely CMs may be present in right ventricular (RV), biatrial, left ventricular (LV)[3], right ventricular outflow tract (RVOT)[4] or heart valves[5,6]. The sporadic type accounts for about 93%, and the multiple type present in familial forms[7]. These rare CMs need to be distinguished from other masses, such as papillary fibroelastoma, rhabdomyoma, lipoma and thrombi[8]. Echocardiographic and clinical features may provide very important information. We reported five rare site of myxoma-like masses, especially pulmonary valve (PV) myxoma was never been reported before. Therefore, our study could provide important value in finding the extra-atrial tumor and making the correct diagnosis.
