Speaking to BLearning at EuroPCR 2019 (21–24 May, Paris, France), Israel Barbash (Tel Aviv, Israel), discusses the TASK study which looked at a “practical tool” used to “assess and predict the risk of stroke during TAVI procedures.” The idea is to “facilitate the decision making on which patients should undergo embolic protection device during the TAVI procedure”.
Barbash outlines some of the clinical predictors for procedural stroke, which include “history of stroke, peripheral vascular disease, low BMI and the use of non balloon-expandable valves” among others.
Barbash and his team designed a “relatively simple” scoring system which allocated patients into low, intermediate, high and very high risk for stroke during the procedure.
Findings from the TASK study indicated that patients in the high risk group had nearly a four-fold increase in terms of procedural stroke risk, while those in the very high group had almost a 10-fold increase. These patients “should be considered for embolic protection device during the procedure”, says Barbash.
