Income and Geographic Disparities in in‐Hospital Mortality Following Cardiovascular Procedures: Evidence From the National Inpatient Sample, 2016–2022

Health Services Research, Volume 61, Issue 2, April 2026.
ABSTRACT Objective To examine whether income‐ and geography‐related disparities in in‐hospital mortality after major cardiovascular procedures arise from differences in patient acuity, hospital characteristics, or inequities within hospitals. Study Setting and Design This observational study analyzed national data on eight major cardiovascular ...

Urgent Open Atrial Transcatheter Mitral Valve Replacement as Bailout for Planned Surgery

JACC: Case Reports, 2020
Hybrid transcatheter mitral valve replacement (TMVR) has shown great promise for patients with severe mitral annular calcification. However, there have been limited reports of its use as a bailout for planned surgical MVR. Here, we present a bailout TMVR
