OUTCOMES OF THE DIFFERENT FLOW/GRADIENT PATTERNS OF AORTIC STENOSIS AFTER AORTIC VALVE REPLACEMENT: INSIGHTS FROM PARTNER 2A TRIAL

OUTCOMES OF THE DIFFERENT FLOW/GRADIENT PATTERNS OF AORTIC STENOSIS AFTER AORTIC VALVE REPLACEMENT: INSIGHTS FROM PARTNER 2A TRIAL

Background: Patients with symptomatic severe AS may be subdivided into 4 subtypes according to LV ejection fraction / flow / gradient pattern: i) High-gradient (HG; mean gradient >= 40 mmHg; Stage D1 in ACC-AHA guidelines); ii) Classical low-flow (LF) low-gradient (LG) (CLF-LG; LVEF=50%, stroke v...

Zusammenfassung:Background: Patients with symptomatic severe AS may be subdivided into 4 subtypes according to LV ejection fraction / flow / gradient pattern: i) High-gradient (HG; mean gradient >= 40 mmHg; Stage D1 in ACC-AHA guidelines); ii) Classical low-flow (LF) low-gradient (LG) (CLF-LG; LVEF=50%, stroke volume index (SVi) < 35 ml/m2, gradient < 40; D3); iv) Normal flow LG (NF-LG; LVEF >=50%, SVi >35 ml/m2, gradient
