Socioeconomic and Racial Disparities: a Case-Control Study of Patients Receiving Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis.

Background: We sought to quantify socioeconomic disparities in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) at an urban, tertiary referral center.

Methods: This retrospective case-control study identified 67 patients with severe AS (aortic valve [AV] area ≤1 cm or AV area index ≤0.60 cm/m or AV velocity ≥40 mmHg) who underwent TAVR from November 5, 2013 to June 10, 2014.
