NPPB and aortic stenosis: B‐type natriuretic peptide (BNP) levels are associated with disease severity, left ventricular (LV) remodeling, and prognosis in severe aortic stenosis (AS).1, 2 While studies have shown the prognostic utility of BNP at baseline and early after transcatheter aortic valve replacement (TAVR) in severe AS patients who underwent TAVR,3, 4, 5, 6, 7, 8, 9, 10 the factors that drive BNP change after AS correction by TAVR remain unclear.
