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.

Introduction : Elevated filling pressures are a hallmark of chronic heart failure. They can be reduced acutely during HF hospitalization but the hemodynamic impact of ongoing therapy to maintain optivolemia has not been established. Methods and Results : After recent HF hospitalization, 274 NYHA Class III or IV HF patients were enrolled in the COMPASS-HF study at 28 experienced HF centers and received intense HF management (average 24.7 staff contacts/ 6 months) ± access to filling pressure information to adjust diuretics to maintain optivolemia, usually defined as estimated pulmonary artery diastolic (PAD) pressure of 12±4 mmHg. Filling pressure information was available for half the patients during the first 6 months (the Chronicle group, <Access), and for all patients during the next 6 months. Diuretics were adjusted 12.7 times per patient in the Chronicle group and 8.2 times per patient in the Control (-Access) group during the first 6 months (p = 0.0001). Compared to baseline, decreases in RV systolic pressure (RVSP) and ePAD were significant for the +Access patients by one year (p=0.0012 and p =.04, respectively). The Control patients exhibited a similar trend 6 months after crossing to +Access (figure ). Conclusions: Targeted therapeutic adjustments, based on continuous filling pressures along with intensification of HF management contacts, are associated with a reduction in chronic left-sided filling pressures and right ventricular load.

ABSTRACT CONTEXT: Obstruction of the right ventricular outflow tract due to metastatic disease is rare. Clinical recognition of cardiac metastatic tumors is rare and continues to present a diagnostic and therapeutic challenge. CASE REPORT: We present the case of a patient who had severe respiratory insufficiency and whose clinical examinations revealed a giant tumor mass extending from the right ventricle to the pulmonary artery. We discuss the diagnostic and therapeutic options. CONCLUSION: In patients presenting with acute right heart failure, right ventricular masses should be kept in mind. Transthoracic echocardiography appears to be the most easily available, noninvasive, cost-effective and useful technique in making the differential diagnosis.
