Insights
Pulmonary artery stenosis is the primary reason for reoperation after arterial switch (Jatene) surgery in patients with transposition of the great arteries. Coronary anomalies are the sole predictor of reoperation need.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease
- Surgical Outcomes
Background:
- Arterial switch operation (Jatene procedure) has been performed since 1989.
- Evaluating outcomes is crucial for identifying reoperation causes and predictors.
- This study focuses on outcomes following arterial switch for d-transposition of the great arteries (d-TGA).
Purpose of the Study:
- To identify the main causes of reoperation after arterial switch surgery.
- To determine variables that predict the need for reoperation in patients with d-TGA.
- To analyze outcomes in a cohort of patients undergoing arterial switch at Santa Marta Hospital.
Main Methods:
- Retrospective analysis of 91 patients with d-TGA.
- Patients underwent arterial switch operation between 1999 and 2016.
- Follow-up averaged 6 years (range 1-21 years).
Main Results:
- Reoperation was required in 21% of patients, with pulmonary artery stenosis being the main indication (47%).
- Overall cumulative mortality was 9.9%.
- Coronary pattern anomalies were the only statistically significant predictor (P<0.05) of reoperation need in both univariate and multivariate analyses.
Conclusions:
- Pulmonary artery stenosis is the leading cause for reoperation post-arterial switch.
- The presence of coronary anomalies is the sole identified predictor for reoperation.
- These findings aid in risk stratification and management of patients undergoing arterial switch for d-TGA.
Introduction:
Jatene surgery or arterial switch is performed at our institution since 1989. It is mandatory to submit our results to an evaluation that allow us to identify the main causes of reoperation and, more importantly, to determine what variables predict the need of reoperation.
Methods:
In this retrospective analysis were included all the 91 patients with d-TGA who underwent an arterial switch operation at Santa Marta Hospital between 1999 and 2016.
Results:
Mean follow-up was 6 years (range 1-21 years). 71% of the patients had simple TGA and 29% had complex TGA. The need of reoperation was 21%(n=19). Pulmonary artery stenosis was the main (47%) indication for reoperation. The overall cumulative mortality was 9.9%. The gender (P= 0.8), diagnosis (simple or complex TGA) (P= 0,5) or the existence of previous surgeries(P=0.9) were unable to predict the need of reoperation. The presence of coronary patterns anomalies was the only variable reaching statistical significance (P< 0.05), both in univariate and multivariate analysis.
Conclusion:
In our series, the main indication for reoperation after arterial switch operation was pulmonary artery stenosis and the only predictive variable was the presence of coronary anomalies.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
