Summary
Aortic valve replacement is a viable option for congenital aortic stenosis when severe calcification, endocarditis, or incompetence is present. Long-term outcomes for this procedure are favorable, emphasizing the need for infective endocarditis prevention.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Context:
- Congenital aortic stenosis often requires surgical intervention.
- Aortic valvotomy is the primary treatment, but aortic valve replacement (AVR) is sometimes necessary.
- This study analyzes AVR for congenital aortic stenosis between 1979-1995.
Purpose:
- To identify indications for AVR in congenital aortic stenosis.
- To determine the frequency of AVR procedures.
- To evaluate early and long-term results of AVR for congenital aortic stenosis.
Summary:
- Eighteen patients underwent AVR for congenital aortic stenosis.
- Indications included severe calcification, endocarditis, and associated regurgitation.
- Reoperations after prior valvotomy were performed in 8 patients.
- Hospital mortality was low (2 deaths), with 1 late death due to prosthetic endocarditis.
- Remaining 15 patients showed excellent long-term results (NYHA Class I-II).
Impact:
- Severely calcified aortic valves, endocarditis, and incompetence are key indications for AVR.
- Prophylaxis against infective endocarditis is crucial pre- and postoperatively.
- AVR offers very good long-term results for congenital aortic valve disease.
