Relative A-Pd reduction above the median of 6.3% was found to significantly predict outcomes after adjusting for preprocedural MR severity in multivariate Cox regression (HR: 0.35, 95% CI: 0.14–0.85, p = 0.02) as well as after adjusting in multivariate regression for other outcome related factors such as NT-proBNP, NYHA class and MR severity (HR: 0.31; 95% CI: 0.11–0.89; p = 0.03). Here, NPPB is linked to miotic rate.
