Giant left atrium in mitral stenosis

Abstract

A 44-year-old male patient presented with breathlessness on exertion but no compressive symptoms. Transthoracic two-dimensional echocardiography revealed a giant left atrium (LA) with severe mitral stenosis (MS) and mild mitral regurgitation (LA size 8.9 cm; LA volume 1133 ml). Giant LA has been variably described in literature, but there is no definition based on LA volume. A giant LA is rarely seen with MS.
