Rapidly growing right atrial myxoma in an older patient with advanced chronic kidney disease: a case report

Abstract

Abstract Background Right atrial myxoma is a rare cardiac tumor, with few reports on its growth rate. Case presentation We found a right atrial myxoma in a male patient in his 80s with chronic kidney disease on the second echocardiogram that was performed for the creation of an arteriovenous fistula at 9 months after the initial echocardiogram, which showed no evidence of myxoma. Echocardiography revealed a mass measuring 37 mm × 28 mm in the right atrium. The patient was asymptomatic, and the tumor was surgically removed. Conclusions To the best of our knowledge, our patient is the oldest compared with all the patients in previously reported cases of rapidly growing right atrial tumors.
