Background: Low-gradient (LG) aortic stenosis (AS) has not been fully characterized compared with high-gradient (HG) AS in terms of cardiac damage, frailty, aortic valve calcification, and clinical outcomes.
Objectives: The aim of this study was to compare the clinical characteristics and outcomes between each hemodynamic type of LG AS and HG AS.
Methods: The current study included 3,363 patients in the CURRENT AS (Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis) Registry-2 after excluding patients without indexed stroke volume or left ventricular ejection fraction (LVEF) data.

Introduction: Pulmonary hypertension (PH) is a common and significant comorbidity in patients with low-flow low-gradient (LF-LG) aortic stenosis, impacting prognosis after transcatheter aortic valve replacement (TAVR). Non-invasive tools often fail to capture PH's full clinical impact due to inherent limitations. This study evaluates the prognostic significance of PH measured invasively and explores its implications on post-TAVR outcomes.

Patients with low-flow, low-gradient severe aortic stenosis and ischaemic cardiomyopathy are at risk for postcardiotomy cardiogenic shock and have a poor prognosis. Although Impella has emerged as a bridge therapy, traditional approaches for Impella insertion are infeasible in patients with peripheral vascular diseases. We successfully managed postcardiotomy cardiogenic shock in a patient with low-flow, low-gradient severe aortic stenosis and ischaemic cardiomyopathy and limited vascular access by introducing Impella via the brachiocephalic artery.
