Background: Outcomes in patients with severe aortic valve stenosis and chronic obstructive pulmonary disease (COPD) have not been extensively studied in literature. Our objective was to use national data to compare outcomes in patients undergoing transfemoral (TF-TAVR) and surgical aortic valve replacements (SAVR).
Methods: We conducted a retrospective cross-sectional analyses using the National Inpatient Sample (NIS) for years 2012 and 2013. The International Classification of Diseases Version 9 (ICD-9) diagnosis and procedure codes were used to identify patient cohorts with COPD, who also had an aortic valve replacement procedure (TF-TAVR or SAVR) during their in-hospital stay. Post-procedure length of stay, inflation-adjusted total hospitalization costs, in-hospital mortality and discharge dispositions were compared among the two groups using propensity-score matched analyses.
Results: Over the two-year period, we found 5,142 patients with COPD, who underwent aortic valve replacements (representing 25,710 patients nationally). Of these, 863 had TF-TAVR and 3,988 had SAVR. Patients undergoing TF-TAVR were sicker (Charlson comorbidity index 3.3 vs 2.8) and older (80.2 vs 71 years). On propensity-score matched analyses, we found that patients with TF-TAVR had a shorter length of stay (6 vs 10.5 days) and higher rates of discharge to home (74.1% vs 48.9%).
Conclusions: In national data, TF-TAVR in COPD patients has better short-term outcomes to SAVR, despite treating sicker patients.
