Prognostic value of left ventricular myocardial work indices in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement
Performance · All-cause mortalityResult — go to the resultHazard ratio 0.639 95% CI 0.463–0.883Authors' conclusion
LV GWI is independently associated with all-cause mortality in patients undergoing TAVR and has a higher prognostic value compared to both conventional and advanced parameters of LV systolic function.
