[Optimal age for the surgical treatment of aortic coarctation. Statistical study on long-term blood pressure values]
Insights
The optimal age for surgical repair of coarctation of the aorta is between 1 and 5 years. Early intervention significantly reduces the risk of developing residual hypertension post-surgery.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Hypertension Research
Context:
- Coarctation of the aorta is a congenital heart defect requiring surgical intervention.
- Late blood pressure outcomes after surgical repair are critical for long-term patient health.
- Determining the optimal surgical timing is essential for minimizing postoperative complications.
Purpose:
- To identify the ideal age for elective surgical correction of coarctation of the aorta.
- To analyze the incidence of residual hypertension based on the age of surgical intervention.
- To provide evidence-based recommendations for pediatric cardiac surgical practice.
Summary:
- A retrospective study analyzed 203 patients operated for coarctation of the aorta.
- Hypertension incidence was significantly lower in patients operated between 1-5 years (11.4%) compared to older age groups.
- Age 1-5 years is identified as the optimal period for elective coarctation of the aorta repair.
Impact:
- Establishes a clear age guideline for coarctation of the aorta repair, improving surgical outcomes.
- Highlights the long-term benefits of early surgical intervention in preventing residual hypertension.
- Contributes to enhanced quality of life for pediatric patients with coarctation of the aorta.
Unlabelled:
A retrospective statistical study on late blood pressure in patients operated for coarctation of the aorta have been done, in order to determine the optimum age for elective surgical treatment. Patients were considered hypertensive when their mean blood pressure exceeded the 90th percentile for their age and sex. The series included 126 isolated coarctation of the aortic isthmus operated at the CMC of the Porte de Choisy. The incidence of residual hypertension at rest in the series is as follows: age 1-5: 16,6 %;age 6-10: 34,3%; age 11-15: 47,5 %. In spite of these results there is no significative difference in the incidence by age group. A similar study by the Massachusetts General Hospital on 77 patients showed essentially the same results. A combination of both series (203 patients) which is possible because the study criteria are the same, gives the following results: age 1-5: 11,4 %;age 6-10: 31,9 %; age 11-20: 40,8 %. There is now a significative difference between age group 1-5 and the others (p Less Than 0,02).
In Conclusion:
the optimum age for elective correction of coarctation of the aorta is 1-5 year. The incidence of residual hypertension is only 11,4 % in that group (70 % confidence limits: 6 to 20%).
