Teen Presentation of Dyssynchronous Left Ventricular Cardiomyopathy Secondary to Wolff-Parkinson-White Syndrome and Right-Sided Septal Pathway.

ABSTRACT:

Background

Wolff-Parkinson-White (WPW) syndrome is associated with an abnormal accessory conduction pathway leading to ventricular pre-excitation and potential re-entrant tachyarrhythmias.

Case summary

A 13-year-old female presents with shortness of breath, cough, and wheezing for 1 day. She was tachycardic with a left bundle branch block. Echocardiographic findings were notable for dyskinetic septal wall motion with a repeat electrocardiogram uncovering pre-excitation pattern consistent with WPW syndrome and an expected right septal or posteroseptal accessory pathway. Tachycardia had self-resolved, and an outpatient radiofrequency ablation (RFA) was scheduled.

Discussion

WPW syndrome with right septal or posteroseptal accessory pathways causes eccentric septal mechan
