Wall-to-wall heart – The largest left atrium ever reported

Abstract

A 59-year-old male patient presented with a history of dyspnea on exertion for the past 10 years, which was gradually progressive in nature. The patient had orthopnea and paroxysmal nocturnal dyspnea for the past few months. On evaluation, he was found to have cardiomegaly and a giant left atrium. Contrast-enhanced computed tomography of the heart showed the left atrium to be enlarged to a dimension of 20.7 cm which, as of the time of writing, is the largest ever reported.
