Table 1 Characteristics of rheumatic MS versus MAC-related degenerative MS

Characteristic	Rheumatic MS	MAC-related degenerative MS
Anatomy	Funnel-shaped geometry	Tubular orifice geometry
Anatomy	Commissural fusion	Commissures spared
Epidemiology	Younger population	Elderly, comorbid population
Echo assessment	MVA quantification validated	MVA quantification challenging
Echo assessment		Greater MVA relative to mean gradient than rheumatic MS
Treatment	PMV if favorable valve morphology without contraindication	Poor valvuloplasty candidates
Treatment	MV replacement	Transcatheter or surgical MV replacement

MS Mitral stenosis, MAC Mitral annular calcification, MVA Mitral valve area, PMV Percutaneous mitral valvuloplasty
