Factors contributing to the mortality associated with open-heart surgery in infants
Insights
Congenital heart disease surgery in infants has improved, but 25% still die. This study analyzed 53 infant deaths to identify factors like inoperable conditions and management errors, suggesting earlier diagnosis and surgery could improve outcomes for pediatric heart patients.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Pediatric Cardiac Surgery
Background:
- Congenital heart disease (CHD) poses a significant mortality risk in infants, with approximately 40% dying within the first year without surgical intervention.
- Surgical outcomes for CHD have improved over time, with current mortality rates for open-heart procedures in infants under one year decreasing to around 25%.
Purpose of the Study:
- To analyze the causes of death in infants who underwent open-heart surgery for congenital heart disease.
- To identify critical management issues in the perioperative care of critically ill infants with CHD.
- To provide insights for improving the prognosis of infants with congenital heart disease through better management strategies.
Main Methods:
- Retrospective analysis of 53 infant deaths following open-heart surgery.
- Data collected from The Hospital for Sick Children, Great Ormond Street, London, between 1973 and 1977.
- Categorization of causes of death including inoperable lesions, preoperative condition, management errors, and infection.
Main Results:
- The study identified 53 deaths, representing a 25% mortality rate among 212 infants undergoing surgery.
- Leading causes of death included inoperable lesions (18 cases), errors in pre-, intra-, and postoperative management (15 cases), and poor preoperative condition (8 cases).
- Infection (2 cases) and unclear causes (10 cases) were also identified as contributing factors.
Conclusions:
- Management errors and delays in diagnosis and treatment significantly impact mortality rates in infants with congenital heart disease.
- Earlier diagnosis and surgical intervention are suggested as crucial for improving survival rates in this vulnerable population.
- Addressing identified management challenges is essential for enhancing the outcomes of pediatric cardiac surgery.
Abstract:
About 40% of children born with congenital heart disease die within the first year of life unless treated surgically. The results of surgery have improved with increasing experience. Currently, the mortality rate of open-heart procedures performed during the first year of life have decreased to about 25%. The present study analyses the causes of death in 53 infants who underwent open heart surgery at the Hospital for Sick Children, Great Ormond Street, London between 1973--1977. Fifty-three deaths represented 25% of the total 212 operated infants. Causes of death and possible contributing factors are discussed under the following headings: Inoperable lesions (18), poor preoperative condition (8), mistake in pre-, intra- and postoperative management (15), infection (2) and unclear (10). It is suggested that earlier diagnosis and operation may improve the results. The purpose of this study was to identify problems in the management of critically ill infants with congenital heart disease and thus improve their prognosis in future.
