Background The purpose of this study was to investigate the correlation between the computed tomography pulmonary artery obstruction index and parameters of functional lung impairment in acute pulmonary embolism, and establish the value of these parameters in prognosticating right ventricular dysfunction and 30-day mortality. Methods This study included 322 consecutive patients (mean age 45.6 ± 13.2 years, 46.9% male) with acute pulmonary embolism, free of other cardiopulmonary disease, who underwent computed tomography pulmonary angiography. Correlations of arterial CO2, O2, and alveolar-arterial oxygen gradient with the computed tomography pulmonary artery obstruction index, measured using the Qanadli score, were analyzed. Logistic regression was used to identify independent predictors of right ventricular dysfunction and 30-day mortality. Results Of the 322 patients, 196 (60.9%) had right ventricular dysfunction, and 58 (18.0%) died within 30 days. The pulmonary artery obstruction index had a significant correlation with partial pressures of arterial O2 ( r = −0.887, p < 0.001) and CO2 ( r = −0.618, p = 0.019) and alveolar-arterial oxygen gradient ( r = +0.874, p < 0.001). Arterial O2 pressure had a good predictive accuracy and discriminative power for both right ventricular dysfunction (sensitivity 80.6%, specificity 85.1%, area under the curve 0.91) and 30-day mortality (sensitivity 77.8%, specificity 82.0%, area under the curve 0.89). Conclusions In patients with acute pulmonary embolism, free of other cardiopulmonary disease, parameters of functional impairment have a strong correlation with computed tomography pulmonary artery obstruction index. Hypoxia is an independent predictor of both right ventricular dysfunction and 30-day mortality in these patients.

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.
