Papillary fibroelastoma of aortic valve is a rare benign tumor that can present with symptoms of obstruction or embolization and can be asymptomatic. The main stay of diagnosis is echocardiography. The size of the tumor affects the sensitivity of transthoracic echocardiography which can miss small size tumors. The treatment is surgical resection. Here, we report a case of papillary fibroelastoma of aortic valve that was detected intraoperatively by transesophageal echocardiography and was missed by transthoracic echocardiography in a patient undergoing coronary artery surgery. The tumor was resected successfully with preservation of aortic valve with no complication. This case highlights importance of intraoperative transesophageal echocardiography in making the diagnosis.
