In this issue of JACC: Cardiovascular Interventions, Stortecky et al. (2) describe the use of multidimensional geriatric assessment (MGA) as a tool to predict mortality and morbidity in a population of 100 patients undergoing TAVR. Sixty-three patients had a Medtronic CoreValve (Medtronic, Minneapolis, Minnesota), and 37 patients had an Edwards Sapien valve (Edwards Lifesciences, Irvine, California) implanted. The MGA consisted of several components designed to assess cognitive and functional capacity such as a Mini Mental State Examination, Mini Nutritional Assessment, Timed Get Up and GO, Basic Activities of Daily Living (BADL), Instrumental Activities of Daily Living, and intensive interrogation with regard to mobility. These tests were then made bimodal by inserting arbitrary cut points that classified test results into probable or improbable findings of cognitive impairment, malnutrition, or immobility. A numerical value was then assigned to the outcomes of each test, which were then summed to provide a combined measure called the frailty index. This index ranged from 0 to 7 points, with ≥3 designating probable frailty.
