McConnell’s Sign

Q: What is McConnell’s Sign?


Answer: McConnell’s sign is a distinct echocardiographic finding in patients with acute pulmonary embolism (PE). It is consistent with akinesia of the mid free wall of the right ventricle but normal motion at the apex. Although echo has a low sensitivity to diagnose PE, but visibilty of McConnell’s sign is very suggestive of PE.
