AIMS: The study aimed at evaluating the reliability and reproducibility of various noninvasive echocardiographic techniques for the estimation of the main hemodynamic parameters in clinical practice. METHODS: A total of 84 patients with a generic indication of right heart catheterization (RHC) executed a transthoracic echocardiography shortly before or after the RHC. All the parameters necessary for a noninvasive hemodynamic evaluation of right atrial pressure, pulmonary artery pressure (PAP), pulmonary capillary wedge pressure, pulmonary vascular resistance and cardiac output were acquired and the agreement with the invasive measures was evaluated by a Bland-Altman analysis. RESULTS: Noninvasive evaluation of right atrial pressure showed a moderate and low correlation with RHC using inferior vena cava parameters (r = 0.517) and tricuspid E/E' ratio (sensitivity 0.23, specificity 0.72), respectively. PAPs estimation from the tricuspid regurgitation peak velocity had a good correlation (r = 0.836) and feasibility (82.1%), as well as PAPm from tricuspid regurgitation mean gradient (r = 0.78, applicability 72.6%) and from pulmonary acceleration time (sensitivity 0.85, specificity 0.5, applicability 92.9%). Pulmonary capillary wedge pressure multiparametric evaluation, as suggested by the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations, showed a good correlation (sensitivity 0.96, specificity 0.59). The noninvasive evaluation of pulmonary vascular resistance and cardiac output did not prove to be clinically accurate. CONCLUSION: Various hemodynamic parameters can be adequately estimated with noninvasive methods. In particular, a multiparametric approach for the evaluation of left ventricle filling pressures is advisable and the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations are reliable even in a heterogeneous population with a significant quota of precapillary pulmonary hypertension.

Abstract

AIMS: The study aimed at evaluating the reliability and reproducibility of various noninvasive echocardiographic techniques for the estimation of the main hemodynamic parameters in clinical practice. METHODS: A total of 84 patients with a generic indication of right heart catheterization (RHC) executed a transthoracic echocardiography shortly before or after the RHC. All the parameters necessary for a noninvasive hemodynamic evaluation of right atrial pressure, pulmonary artery pressure (PAP), pulmonary capillary wedge pressure, pulmonary vascular resistance and cardiac output were acquired and the agreement with the invasive measures was evaluated by a Bland-Altman analysis. RESULTS: Noninvasive evaluation of right atrial pressure showed a moderate and low correlation with RHC using inferior vena cava parameters (r = 0.517) and tricuspid E/E' ratio (sensitivity 0.23, specificity 0.72), respectively. PAPs estimation from the tricuspid regurgitation peak velocity had a good correlation (r = 0.836) and feasibility (82.1%), as well as PAPm from tricuspid regurgitation mean gradient (r = 0.78, applicability 72.6%) and from pulmonary acceleration time (sensitivity 0.85, specificity 0.5, applicability 92.9%). Pulmonary capillary wedge pressure multiparametric evaluation, as suggested by the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations, showed a good correlation (sensitivity 0.96, specificity 0.59). The noninvasive evaluation of pulmonary vascular resistance and cardiac output did not prove to be clinically accurate. CONCLUSION: Various hemodynamic parameters can be adequately estimated with noninvasive methods. In particular, a multiparametric approach for the evaluation of left ventricle filling pressures is advisable and the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations are reliable even in a heterogeneous population with a significant quota of precapillary pulmonary hypertension.
