Aortic stenosis is life-threatening
Progression of aortic stenosis1
Valvular aortic stenosis is progressive and life-threatening. Once symptoms appear, untreated patients have a poor prognosis; they will experience worsening symptoms, eventually leading to death. After the onset of symptoms, average survival is 50% at two years and 20% at five years.1
