Invasive versus non-invasive assessment of valvuloarterial impedance in severe aortic stenosis

Invasive versus non-invasive assessment of valvuloarterial impedance in severe aortic stenosis

Background As a measure of the global left ventricular afterload, valvuloarterial impedance (ZVA) can be estimated using transthoracic echocardiography (TTE) and invasive measuring methods. The objective of this study was to compare the performance of TTE in measuring ZVA with invasive haemodynamics...
