The role of left ventricular global work index on the prediction of cardiovascular mortality after transcatheter aortic valve implantation

Echocardiography is used for assessment of patients after transcatheter aortic valve implantation (TAVI). In Anwer's study [1], they aimed to investigate whether the Global work index (GWI) integrates LV deformation may be advantageous for long-term follow-up. In the multivariable Cox regression of this study, they found that the GWI independently improved an LV systolic function model including LV ejection fraction (LVEF) and global longitudinal strain (GLS). Similarly, GWI but not LVEF independently improved the outcome association of different clinical models.
