Abstract
McConnell’s sign is a well-established, specific echocardiographic sign for acute pulmonary embolism. Multiple theories have been proposed regarding the mechanism of McConnell’s sign in the context of acute pulmonary embolism. Here, we present 2 patient cases in which McConnell’s sign was seen with right ventricular ischemia without pulmonary embolism. (Level of Difficulty: Beginner.)
