Catheter ablation of hemodynamically compromising incessant atrioventricular tachycardia.
A 27-year-old woman was admitted to the Georgetown University Hospital with refractory hemodynamically compromising incessant atrioventricular tachycardia. A single left-sided accessory pathway was identified and successfully modified acutely. Endocardial delivery of direct current energy provided an extremely effective therapeutic intervention resulting in termination of atrioventricular tachycardia and restoration of stable hemodynamic status. Although a second ablation procedure was necessary to permanently interrupt accessory pathway conduction, the patient has remained free of symptoms without medications for 13 months.
