Aortic stenosis
incomplete-TODO: management strategies / red flags
pathogenesis
- LV needs to generate more force to overcome the narrow valve
- → LV failure
- ↓ LV end diastolic pressure = ↓ coronary perfusion pressure
- critical AS → pulmonary hypertension
managing the sick AS patient
- avoid AF
- keep well-filled
- preserve contractility - avoid beta blockers, CCBs
