Noninvasive Assessment of Left Ventricular Pressure-Volume Relations : Inter- and Intraobserver Variability and Assessment Across Heart Failure Subtypes
A novel method to derive pressure-volume (PV) loops noninvasively from cardiac magnetic resonance images has recently been developed. The aim of this study was to evaluate inter- and intraobserver variability of hemodynamic parameters obtained from noninvasive PV loops in healthy controls, subclinical diastolic dysfunction (SDD), and patients with heart failure with preserved ejection fraction, mi
