Frailty and aortic valve disease

Frailty is a common occurrence in elderly persons and is present in approximately half of the patients being screened for transcatheter aortic valve replacement (TAVR) therapy. Accurate assessment of the likelihood of benefit from intervention in the older patient with aortic stenosis is critical with both surgical aortic valve replacement and TAVR now available. Whereas risk algorithms are available that are helpful in predicting outcomes in patients undergoing surgical procedures, measures of frailty are not included in the algorithms. When considering intervention in the elderly patient, the addition of frailty assessment to determine the true risk in this population is essential to determine potential benefit. Gait speed as determined by the 5-m walk test is the most commonly used single test objective measurement of frailty in patients undergoing cardiac surgery and is an independent predictor of mortality and major morbidity. Wider application of this and other objective measures of frailty in the population undergoing TAVR is necessary to determine whether it is predictive in this population also
