Asymptomatic giant prolapsing right atrial myxoma: Comparison of transthoracic and transesophageal echocardiography in pre-operative evaluation

Abstract

We present a 65 years old asymptomatic patient with a giant prolapsing right atrial myxoma diagnosed echocardiographically and compare the transthoracic echocardiography and transesophageal two-dimensional features. Transesophageal echocardiography yielded a more accurate measurement of the correct dimensions of the tumour as compared with pathological findings, it also demonstrated clearly existing calcifications, the attachment and precise site of tumour pedunculation, showed haemodynamic changes, eliminated the possibility of other tumour foci. Transesophageal echocardiography gave correct anatomical and surgical data pre-operatively.
