S. R. Mittal DM, Ajmer, India

 A 65-year-old asymptomatic male was referred for unexplained mild cardiomegaly. Electrocardiogram was unremarkable. Echocardiography revealed significant enlargement of right atrium (RA) (Figure 1a). Left atrium (LA) was normal in size (anteroposterior dimension 32 mm in parasternal long axis view) and was not compressed. Both ventricles were normal in dimensions and showed normal contractility.
