Rv lv ratio right heart strain.

Right heart strain or more precisely right ventricular strain is a term given to denote the presence of right ventricular dysfunction usually in the absence of an underlying cardiomyopathy. This retrospective cohort study included 579 consecutive subjects 08 2003 03 2010 diagnosed with acute pe with normal ct rv lv ratio 0 9 236. Kumamaru kanako k et al. The right ventricular to left ventricular diameter rv lv ratio measured at ct pulmonary angiogram ctpa has been shown to provide valuable information in patients with pulmonary arterial hypertension and to predict death or deterioration in acute.

The finding of a right heart thrombus in the setting of pe and rv strain doubles the mortality up to 29 echo identified right heart thrombus most likely requires more aggressive treatment such as embolectomy or lytic therapy compared to heparin alone however this requires further investigation. The objective of this study is to identify a clinical scenario for which normal ct derived right to left ventricular rv lv ratio is sufficient to exclude rv strain or pe related short term death. Patients with interstitial lung disease ild may develop pulmonary hypertension ph often disproportionate to the severity of the ild.
