Transthoracic echocardiographic images showing two large atrial masses as well as extreme LA dilatation. A Apical four-chamber view illustrating a large pedunculated homogenous, well-demarcated mass with 42Â mm*21Â mm dimensions attached to right atrial appendage (indicated via a blue oblique arrow). B Apical five-chamber view showing concomitant presence of two atrial masses. The vertical white arrow points to a large lobulated mass in LA with well-defined borders attached to LAA (red asterisk) with a stalk. Red arrowheads depict the apical to mid ventricular extension of hypertrophy. LV: left ventricle, RV: right ventricle, LA: left atrium, RA: right atrium
