In-hospital outcomes of percutaneous mitral valve repair in patients with chronic obstructive pulmonary disease: insights from the national inpatient sample database

Abstract

Objectives: We aimed to assess the in-hospital outcomes in patients with mitral regurgitation treated with percutaneous mitral valve repair (PMVR) among patients with chronic obstructive pulmonary disease (COPD). Background: There is lack of data on the outcomes of PMVR for mitral regurgitation in patients with COPD. Methods: We analyzed the national inpatient sample (NIS) database from January 2012 to December 2016. Results: A total of 9125 patients underwent PMVR in the period between January 2012 and December 2016, of whom 2,495 (27.3%) patients had concomitant COPD. Comparing COPD patients to non-COPD patients, COPD patients had higher proportion of females (48.3% vs. 46.6%, p =.16), were younger (75.8 ± 10.0 years vs. 76.4 ± 12.2 years; p =.04), had higher prevalence of peripheral vascular disease (17.4% vs. 13.5%; p
