Insights
Systemic-to-pulmonary shunts are a safe palliative procedure for children with cyanotic congenital heart disease. This study found excellent outcomes with low mortality and reintervention rates, emphasizing meticulous surgical care.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
Background:
- Systemic-to-pulmonary shunts are crucial palliative procedures for cyanotic congenital heart disease.
- Existing morbidity and mortality necessitate evaluating shunt procedure outcomes and risk factors.
Purpose of the Study:
- To report outcomes of systemic-to-pulmonary shunts in pediatric patients.
- To identify risk factors associated with adverse events following these procedures.
Main Methods:
- Retrospective analysis of 42 patients undergoing systemic-to-pulmonary shunts from 2013 to 2024.
- Data collected from electronic medical records, including demographics, operative, and postoperative details.
Main Results:
- Excellent overall results with one operative mortality and no discharge mortality in 42 patients.
- Low reintervention rate (four cases) and similar outcomes across different shunt types, sizes, approaches, and diagnoses.
Conclusions:
- Systemic-to-pulmonary shunts are demonstrated as safe and reliable in a tertiary hospital setting.
- Meticulous surgical techniques and standardized postoperative care protocols are key to optimizing patient outcomes.
Objectives:
A systemic-to-pulmonary shunt is the palliation of choice for many children with cyanotic congenital heart disease. However, significant morbidity and mortality related to these procedures and the postoperative course still exists. We aim to report our outcomes of systemic-to-pulmonary shunts as well as to define certain risk factors for adverse events.
Materials And Methods:
We retrospectively collected data from the electronic medical records of Ramathibodi hospital from January 01, 2013, to April 30, 2024. Demographic data, operative, and postoperative details were collected and reviewed. Inclusion criteria included patients whose primary operation was a systemic-to-pulmonary shunt. Exclusion criteria were patients diagnosed with hypoplastic left heart syndrome and whose medical record data were missing significant information.
Results:
There were initially 56 patients eligible for our study. After exclusion, the total number of patients enrolled was 42. Overall the results were excellent, with only one operative mortality, no discharge mortality, and four reinterventions. Outcomes between different shunt types, shunt sizes, surgical approaches, and diagnoses were statistically similar.
Conclusions:
We demonstrate that systemic-to-pulmonary shunts are a safe and reliable procedure based on our results at a tertiary hospital in Thailand. We emphasize meticulous surgical techniques as well as utilization of proper and reproducible postoperative care protocols to optimize patient outcomes.
