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.
