Tomtec Inc 4d rv-function 2
Results of the external validation. ( A–C ) Agreement between the invasively measured pressure curves (i.e. ground truth) and those predicted by the three investigated methods using the invasively derived peak systolic pressure as input. ( D–F ) Agreement between the invasively measured pressure curves (i.e. ground truth) and those predicted by the three investigated methods using the non-invasively derived peak systolic pressure (i.e. the peak RV pressure estimated from the Doppler <t>echocardiography–derived</t> peak velocity of the tricuspid regurgitation jet) as input. The thick red line indicates the mean difference. LV, left ventricular; PVC, pulmonary valve closure; PVO, pulmonary valve opening; RV, right ventricular; TVC, tricuspid valve closure; TVO, tricuspid valve opening.
4d Rv Function 2, supplied by Tomtec Inc, used in various techniques. Bioz Stars score: 90/100, based on 1 PubMed citations. ZERO BIAS - scores, article reviews, protocol conditions and more
