Chronic Obstructive Pulmonary Disease in Patients Undergoing Transcatheter Aortic Valve Implantation:
This study evaluated the effects of COPD on outcomes after TAVI in 319 pts, 30% of whom had COPD. COPD pts had a lower survival rate at 1 yr (71% vs 85%) and experienced less improvement in functional status. Cumulative mortality was predicted by the 6 min walk test, and periprocedural pulmonary complications were predicted by FEV1. TAVI was deemed futile in 40% of COPD pts.
