- •
RVD, predefined per guidelines as TAPSE < 16 mm, is very common in this challenging group of patients with severe AS, LV dysfunction, and LFLG physiology.
- •
Baseline RVD is an independent predictor of all-cause mortality despite adjustments of several potential confounders adding to the current risk stratification.
- •
Identification of RVD should be used in conjunction with calculation STS-PROM score and FR status, obtained with DSE, to better predict surgical risk and all-cause mortality in these complex patients.
