- Right Ventricular Dysfunction and Pulmonary Obstruction Index at Helical CT: Prediction of Clinical Outcome during 3-month Follow-up in Patients with Acute Pulmonary Embolism Key Points
“The scans were evaluated by measuring the minor axes of the right and left ventricles of the heart in the transverse plane at their widest points between the inner surface of the free wall and the surface of the interventricular septum. These maximum dimensions may be found at different levels. CT scans were considered to show no RVD if the ratio was 1.0 or less, modest RVD if the ratio was greater than 1.0 but less than or equal to 1.5, and severe RVD if the ratio was greater than 1.5, as recommended in the literature.”
“Results of post hoc testing showed that in patients who died of PE, the mean RV/LV ratio was significantly higher than that in patients who survived (1.54 ± 0.18 vs 1.14 ± 0.03, P = .005).”
“The negative predictive value for an uneventful outcome with an RV/LV ratio of 1.0 or less was 100%.”

“As a general rule, a minimum distance of 10 mm between the annular plane and the coronary ostia is recommended.”
