Abstract
<p><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Introduction: Cardiac AngioCT has established itself as an essential method of cardiac imaging over the latest years, namely in the pulmonary hypertension (PH) field. PH is a multifactorial disease and its diagnosis relies on invasive hemodynamic parameters by right heart catheterization (RHC). AngioCT acquires cardiac and great vessel images in its standard views – axial and four-chamber (4C) rendered – and has the potential to replace the need for some invasive diagnostic procedures.</span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Purpose: To compare data from measurements obtained with AngioCT in 4C and axial views with hemodynamic parameters in PH patients.</span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Methods: Consecutive pts with precapillary PH were submitted to angioCT and RHC within a median interval of 6 months. AngioCT measurements in both axial and 4C views and hemodynamic parameters from RHC were collected. ROC curve analysis was used to evaluate the association between CT measurements and an established cut-off of mean pulmonary artery pressure (mPAP) of 35mmHg.</span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Results: We selected 47 patients (mean age: 64±16 years, 60% male) 12 with group 1 PH and 37 with group 4 PH. Patients had a mean mPAP of 44±16mmHg, NT-proBNP 1109±1860ng/mL, 56% were in OMS functional class (FC) II and 21% in FC III.</span></span></p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Right ventricular area (RVA) and right atrial area (RAA) in axial and 4C views significantly correlated with mPAP (RVA axial: r 0.463, p=0.001; RVA 4C: r0.405, p=0.006, RAA axial: r 0.374 , p=0.01 ; RAA 4C: r 0.595, p <0.001), independently from pts’ PH clinical group.</span></span></p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">In ROC analysis, both RVA in axial and 4C view had a significant association with mPAP≥ 35mmHg (AUC 0.839, p<0.001; AUC 0.740 p=0.012, respectively) and pulmonary vascular resistance (RVP). Likewise, RAA in axial and 4C view were associated with mPAP ≥35mmHg (AUC 0.56, p<0.000; AUC 0.856 p<0.001; AUC 0.785, p = 0.003 respectively).</span></span></p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Neither of these views showed superiority in predicting severe PH (RV 4C and axial, p = 0.08; RA 4C and axial, p = 0.18).</span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Conclusion:</span></span></p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:"Calibri",sans-serif">Our findings support that in PH population, axial view is no different from 4C view measurements and that they have equivalent associations with hemodynamic parameters. These results may obviate the need to render 4C chamber in several settings and thus optimize time and resources.</span></span></p>
