This study sought to characterize the long-term effect of chronic lung disease (CLD) on mortality, clinical outcomes, quality of life, and health benefits after transcatheter aortic valve replacement (TAVR) with a self-expanding bioprosthesis.


The long-term effect of CLD after TAVR is unknown.


Prevalence and severity of CLD was determined at baseline in high- and extreme-risk patients with aortic stenosis from the CoreValve US Pivotal Trial. Clinical outcomes and health status were assessed using the Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ-OS). A favorable health benefit was defined as alive with a KCCQ-OS ≥60 and stability (<10-point decrease) or improvement in the KCCQ-OS from baseline.


CLD was present in 55% (20% mild, 13% moderate, 22% severe) of the 1,030 patients studied. All-cause mortality was higher in patients with moderate and severe CLD at 1 year (19.6% mild, 28.1% moderate, 26.9% severe CLD vs. 19.2% non-CLD; p = 0.030) and 3 years (44.8% mild, 53.0% moderate, 51.9% severe vs. 37.7% non-CLD; p < 0.001). New York Heart Association functional class improved in more than 80% of patients with CLD at 1 and 3 years. All patients had a nearly 20-point improvement in KCCQ-OS at 1 and 3 years. However, only 43.3% of patients with CLD had a favorable health benefit at 1 year and 22.5% at 3 years.


Moderate and severe CLD increases 1- and 3-year mortality after TAVR. Although functional status and quality of life were improved in CLD at 1 and 3 years after TAVR, a favorable health benefit was only achieved in selected patients.
