McConnell's sign: Echocardiography in the management of acute pulmonary embolism

Abstract

Management of acute pulmonary embolism depends immensely on rapid diagnosis and early intervention. Transthoracic echocardiography has gained favorability in scenarios where diagnostic computed tomography angiography is not feasible. McConnell's sign, an echocardiographic finding of segmental right ventricular wall-motion abnormality with apical sparing, is highly specific and may guide therapeutic intervention. We present the case of a 59-year-old man who was found to have acute pulmonary embolism with obstructive shock, managed successfully with thrombolytic therapy after identification of McConnell's sign. We review current literature and develop a framework for the integration of echocardiography into the multimodal approach to management.
