McConnell Caught in 3D: Comparison with Other Etiologies of Right Ventricular Failure

The McConnell sign is a well-recognized 2D echocardiographic feature of pulmonary embolism characterized by apparent hypokinesia of right ventricular mid and apical free wall segments. However, it is rarely described in 3D echocardiography. We report a case of high-risk pulmonary embolism with the McConnell sign demonstrated in 3D echocardiography. Comparison with other etiologies of right ventricular dysfunction regarding 3D morphology and 2D speckle tracking strain is also discussed.
