Systematic review reveals CT RV/LV ratio over 1.0 reliably marks right ventricular dysfunction in acute pulmonary embolism, indicating significant prognostic value for predicting adverse outcomes.
Our study demonstrates a lack of definite standardization in measuring CT RV/LV ratio in acute PE. Based on our review, we propose an RV strain defined as CT RV/LV ratio >1.0 measured on a single axial CT slice as an easily measurable and reliable marker of RV dysfunction in acute PE, with associated significant prognostic value in predicting adverse outcomes.
