Abstract
BackgroundMcConnell’s sign is a specific echocardiographic finding that was first described in patient with acute pulmonary embolism signifying right ventricular dysfunction. It remains an under-recognized sign in patients with right ventricular infarction.Case PresentationAn 80-year-old woman presented with sudden onset chest pain and breathlessness. The electrocardiogram showed features suggestive of inferior, posterior, and right ventricular infarction with complete heart block and McConnell’s sign was seen on the echocardiography. CT pulmonary angiogram ruled out the present of pulmonary thromboembolism. Coronary angiogram revealed an occluded right coronary artery with collateral supply from the left circulation. Medical management was planned after patient-physician discussion. Patient symptomatically improved with medical management.ConclusionAlthough McConnell’s sign is suggestive of acute pulmonary embolism, it may also be present in patients with right ventricular dysfunction due to infarction. The presence of McConnell’s sign in a patient presenting with acute coronary syndrome should prompt evaluation for right ventricular infarction in the absence of acute pulmonary embolism.
