McConnell’s Sign in the Absence of Pulmonary Embolism

McConnell’s sign is an echocardiographic finding characterized by hyperdynamic motion of the right ventricular (RV) apex with akinesis of the RV free wall. It is widely known as an indicator of RV strain in acute pulmonary embolism (PE) but has been described in other conditions such as sepsis-induced RV dysfunction, acute cor pulmonale, and right-sided heart failure. In critically ill patients, RV dysfunction is a major contributor to hemodynamic instability, respiratory failure, and poor outcomes. Given the overlapping signs of various underlying conditions, McConnell’s sign serves as a useful marker for assessing RV involvement but can be challenging to interpret as an initial imaging finding. Here, we present a rare case of McConnell’s sign seen in a patient in the absence of a PE.
