Ebstein's anomaly with coarctation of the aorta. An unusual association
Insights
Ebstein's anomaly with coarctation of the aorta is rare. Surgical correction of coarctation showed good outcomes, but tricuspid valve dysplasia persisted in some patients.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Ebstein's anomaly and coarctation of the aorta are rare co-occurring congenital heart defects.
- This report details three male pediatric cases with this combined anomaly.
Observation:
- Three male patients (7 months, 4 years, 14 years) presented with Ebstein's anomaly and coarctation of the aorta.
- Two patients had atrioventricular and ventriculoarterial discordance, experiencing neonatal heart failure.
- The third patient had concordance, Wolf-Parkinson-White syndrome, and paroxysmal tachycardia.
Findings:
- All patients underwent successful surgical correction of coarctation of the aorta.
- The patient with concordance received tricuspid valvuloplasty and anomalous pathway ablation.
- Postoperative outcomes were good for two years, though tricuspid valve dysplasia persisted in discordant cases.
Implications:
- Surgical correction of coarctation is feasible in complex Ebstein's anomaly.
- Tricuspid valve dysplasia remains a challenge, requiring ongoing management.
- This case series highlights the management of a rare congenital heart defect combination.
Abstract:
Ebstein's anomaly with coarctation of the aorta is an extremely unusual condition. In this report, the clinical and surgical features of 3 male patients, aged 7 months, 4 years and 14 years, are discussed. All patients were in situs solitus. The first 2 patients had atrioventricular and ventriculoarterial discordance and progressed to heart failure in the neonatal period. The third had atrioventricular and ventriculoarterial concordance, as well as Wolf-Parkinson-White syndrome, with frequent episodes of paroxysmal tachycardia. The 3 patients underwent surgery for correction of the coarctation of the aorta. The patient with atrioventricular and ventriculoarterial concordance underwent tricuspid valvuloplasty using a DeVega-like technique. In addition, ablation of 2 anomalous pathways (Kent bundle), which were detected by the electrophysiologic study, was also subsequently performed. The 3 patients showed a good postoperative outcome for 2 years, although, in those with discordance, the surgical procedure did not influence the dysplasia of the tricuspid valve, because this valve showed light to moderate dysfunction.
