Résumé
In recent studies, a 5-stage cardiac damage classification in severe aortic stenosis (AS) based on echocardiographic parameters has shown to provide predictive value regarding clinical outcome. The objective of this study was to investigate the prognostic impact of a cardiac damage classification based on invasive hemodynamics in patients with AS undergoing transcatheter aortic valve replacement (TAVR). A total of 1400 patients with symptomatic AS and full invasive hemodynamic assessment before TAVR were included. Patients were categorized according to their cardiac damage stage into five groups that are defined as: stage 0, no cardiac damage; stage 1, left ventricular damage; stage 2, left atrial and/or mitral valve damage; stage 3, pulmonary vasculature and/or tricuspid valve damage; stage 4, right ventricular damage. 9.9% patients were classified as stage 0, 23.6% as stage 1, the majority of patients as stage 2 (33.5%), 23.1% as stage 3 and 10% as stage 4. One- and 4-year mortality were 10.1%/29.5% in stage 0, 16.1%/60.6% in stage 1, 17.3%/39.4% in stage 2, 22%/54.6% in stage 3, 27.1%/62.2% in stage 4 (p = 0.001/p < 0.001). The extent of cardiac damage was independently associated with increased mortality after TAVR (HR 1.16 per each increment in stage, 95% confidence interval 1.03-1.18; p = 0.018). Cardiac damage staging in severe AS patients based on invasive hemodynamics appears to show strong association between the extent of cardiac damage and post-TAVR mortality.

BACKGROUND
BACKGROUND
In recent studies, a 5-stage cardiac damage classification in severe aortic stenosis (AS) based on echocardiographic parameters has shown to provide predictive value regarding clinical outcome. The objective of this study was to investigate the prognostic impact of a cardiac damage classification based on invasive hemodynamics in patients with AS undergoing transcatheter aortic valve replacement (TAVR).
METHODS
METHODS
A total of 1400 patients with symptomatic AS and full invasive hemodynamic assessment before TAVR were included. Patients were categorized according to their cardiac damage stage into five groups that are defined as: stage 0, no cardiac damage; stage 1, left ventricular damage; stage 2, left atrial and/or mitral valve damage; stage 3, pulmonary vasculature and/or tricuspid valve damage; stage 4, right ventricular damage.
RESULTS
RESULTS
9.9% patients were classified as stage 0, 23.6% as stage 1, the majority of patients as stage 2 (33.5%), 23.1% as stage 3 and 10% as stage 4. One- and 4-year mortality were 10.1%/29.5% in stage 0, 16.1%/60.6% in stage 1, 17.3%/39.4% in stage 2, 22%/54.6% in stage 3, 27.1%/62.2% in stage 4 (p = 0.001/p < 0.001). The extent of cardiac damage was independently associated with increased mortality after TAVR (HR 1.16 per each increment in stage, 95% confidence interval 1.03-1.18; p = 0.018).
CONCLUSIONS
CONCLUSIONS
Cardiac damage staging in severe AS patients based on invasive hemodynamics appears to show strong association between the extent of cardiac damage and post-TAVR mortality. This staging classification provides predictive value and may improve risk stratification, therapy management and decision-making in patients with AS. Invasive Staging Classification of Cardiac Damage in Severe Symptomatic Aortic Stenosis has an Impact on Outcome after TAVR.
