The purposes of the present study were to determine the impact of chronic obstructive pulmonary disease (COPD) on Valve Academic Research Consortium-defined outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). A total of 3,933 consecutive patients underwent TAVI from January 2010 to December 2011 in 34 centers and were included in the French national TAVI registry "FRANCE 2"; 895 (22.7%) had concomitant COPD, 3,038 (77.3%) did not. There were no significant differences in procedural characteristics or 30-day Valve Academic Research Consortium-defined outcomes between those with and without COPD. Multivariate regression analysis showed COPD to be an independent predictor of 1-year mortality and combined efficacy end point after adjustment for concomitant co-morbidities (hazard ratio 1.19, 95% confidence interval 1.005 to 1.41, p = 0.03 and hazard ratio 1.52, 95% confidence interval 1.29 to 1.79, p <0.001, respectively). The higher mortality rate at 1 year in patients with COPD was related to cardiovascular deaths (COPD 10.0% vs non-COPD 6.2%, p = 0.008). Subgroup analysis found that the effect of COPD on 1-year mortality rate was constant across different subgroups, especially the type of approach and the type of anesthesia subgroups. In conclusion, concomitant COPD in patients referred for TAVI characterizes a high-risk population. The excess in mortality is largely determined by a higher rate of cardiovascular deaths and exists regardless of the type of procedure performed and its results.
