Abstract
Introduction: Mitral stenosis (MS) severity is determined by mitral valve area (MVA); the threshold for severe MS was raised from MVA of 1.0 cm to 1.5 cm in recent guidelines.Hypothesis: This study aimed to compare the clinical outcomes, according to percutaneous mitral valvuloplasty (PMV) versus mitral valve replacement (MVR) treatment strategy, of severe MS patients with the updated criteria for the subgroups categorized by MVA of 1.0 cm and 1.5 cm.Methods: From the Multicenter mitrAl STEnosis with Rheumatic etiology (MASTER) registry of 3,140 patients, we included severe MS patients who underwent PMV or MVR between January 2000 and December 2021 except previous valvular surgery/intervention, at least moderate other valvular dysfunction, and thrombus at the left atrium/appendage. Moderately severe MS (MS-MS) and very severe MS (VS-MS) were defined as 1.0 cm
