Summary
Congenital heart valve disease in pediatric patients undergoing mitral and aortic valve replacement (MVR, AVR) shows higher complication rates and lower survival than acquired disease. These findings highlight challenges in congenital valve repair.
Area of Science:
- Cardiovascular Surgery
- Congenital Heart Disease
- Prosthetic Valve Research
Context:
- Analysis of 365 mitral and aortic valve replacement (MVR, AVR) cases between 1968-1983.
- Identified 20 congenital cases (5.5%) with valvular disease present from birth or early childhood.
Purpose:
- To compare outcomes of MVR and AVR in congenital versus acquired valvular disease.
- To assess survival rates, prosthesis malfunction, and complications in congenital cases.
Summary:
- Congenital MVR/AVR patients had a mean age of 5.6 and 22.4 years, respectively.
- Predominant pathologies included regurgitation for both mitral and aortic valves.
- Congenital cases were frequently associated with other cardiac anomalies.
Impact:
- Congenital cases exhibited lower 15-year survival rates compared to acquired disease groups.
- Higher incidences of prosthesis malfunction, complications, and late deaths were observed in congenital cases.
- Xenograft calcification was a cause of late deaths in MVR and AVR congenital groups.
