Key Points in Estimating Pulmonary Vascular Hemodynamic Parameters
Dear Editor,
I have read the manuscript comparing the hemodynamic measurements of pulmonary vascular bed obtained from transthoracic echocardiography and invasive right heart catheterization with great interest. The authors reported that although the results of both diagnostic interventions correlate with each other, nearly half of echocardiographic measurements of systolic pulmonary artery pressure and right atrial pressure are accurate.
