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.
Rv lv ratio right heart strain.
Normal ventricular diameter ratio on ct provides adequate assessment for critical right ventricular strain among patients with acute pulmonary embolism the international journal of cardiovascular imaging 32 7 2016.
Right ventricular rv assessment has long been challenging and technically difficult using echocardiography.
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.
It can manifest as an acute right heart syndrome.
