 abstracta 56-year - old man was admitted to our hospital for coronary artery bypass graft surgery . 
 preoperative transthoracic echocardiography revealed thickening of the anterior leaflet of the tricuspid valve , and transesophageal echocardiography showed oval and irregular - shaped masses , featuring well - demarcated borders and a homogenous texture , attached to the atrial side of the anterior leaflet of the tricuspid valve with a small , tiny , mobile stalk . in the operating room , this mass was resected and gross anatomical examination showed multiple finger - like fronds attached to the stalk . when it was placed in saline , the 
 mass revealed typical  sea anemone  , suggestive of papillary fibroelastoma . 
 although echocardiography had been previously conducted for routine preoperative evaluation , this incidental finding significantly changed the surgical plan .
