Transcatheter Aortic Valve Replacement
The New Gold Standard for Aortic Valve Replacement in Elderly Patients
Treatment for Aortic Stenosis:
Therapy is based on the degree of aortic stenosis and the feasibility of various treatment approaches.
Medical management and follow up is indicated for patients with a mild degree of aortic stenosis. This is by routine follow up clinic visits and echocardiograms at these visits.
Patients with symptomatic or a severe degree of aortic stenosis are recommended aortic valve replacement.
Patients who are symptomatic from severe aortic stenosis have a 50 % probability of survival at 2 years.
Surgical aortic valve replacement is performed using either a conventional sternotomy or one of the minimally invasive approaches.
TAVR or TAVI is indicated for those:
- Who are too frail to undergo open heart surgery
- Have multiple co-morbid conditions rendering open heart surgery extremely high rish
- Have had a previous heart surgery
- Have had a previous aortic valve replacement (biologic/ bioprosthetic) and the valve is failing
- Whose heart function is significantly depressed to withstands open heart surgery
