To report a rare case of Ebstein's anomaly (EA) in a patient with Williams syndrome (WS) presenting with life-threatening arrhythmias, highlighting its significance in clinical practice.
Key Findings:
The patient had severe Ebstein's anomaly with significant tricuspid valve displacement, which is critical for understanding the severity of the condition.
Ventricular arrhythmias were linked to dyskinetic areas of the Purkinje system, indicating a need for targeted management strategies.
This case represents the third documented instance of EA in a patient with WS, underscoring the rarity and clinical importance of this association.
Interpretation:
The combination of WS and EA can lead to severe cardiac complications, including life-threatening arrhythmias, necessitating careful monitoring and management strategies for affected patients.
Limitations:
The rarity of the case limits generalizability.
No likely pathogenic variants were identified despite extensive genetic testing.
Lack of long-term follow-up data on the patient's cardiac health post-treatment.
Conclusion:
This case highlights the need for awareness of potential cardiac complications in patients with Williams syndrome, particularly those with Ebstein's anomaly, and suggests specific monitoring strategies for clinicians.
