Recently, a staging classification of cardiac damage in aortic stenosis (AS) based on echocardiographic measurements has been shown to provide prognostic information after aortic valve replacement (AVR; Généreux P et al. Eur Heart J 2017). We aimed to validate this principle by creation of an analogous five stage classification based on invasive hemodynamics. Methods: We studied 422 patients (age 75±10 years, 59% males) with severe AS [indexed aortic valve area (iAVA) 0.41±0.13 cm 2 /m 2 ]

The five stages of cardiac damage were defined as follows: stage 0: no cardiac damage: absence of any of the following criteria, stage 1: left ventricular damage: left ventricular end-diastolic pressure >15 mmHg, stage 2: left atrial damage: mean pulmonary artery wedge pressure >15 mmHg, stage 3: pulmonary vascular damage: pulmonary vascular resistance >3 Wood units and/or invasively assessed systolic pulmonary artery pressure >60 mmHg, stage 4: right ventricular damage: mean right atrial pressure >15 mmHg. Patients were hierarchically classified in a given stage (worst stage) if the criterion was met for that stage.
