Mx of MS
MEdical therapy
-BB, diuretics if overloaded
Balloon valvuloplasty
Indications for Balloon valvuloplasty in MS
Mod to severe MS (<1.5 cm2 area)
Symptomatic
Asymptomatic +
- New AF

Contraindications for balloon valvuloplasty in MS
> mild MR
LA thrombus
Heavy calcification
Predominant subvalvular involvement
Indications for AR repair
If Symptomatic - Treat
If asymptomatic:
- Resting EF <50%
- Cardiac surgery/CAGS
- Rest EF >50%, but LV Diastolic >70mm or LV systolic >50 mm
Indication for ICD
PRimary -1 month post MI with LVEF <35%
Secondary
