Atrioventricular nodal re-entrant tachycardia in a patient with Ebstein anomaly.
نویسندگان
چکیده
The first case of successful slow pathway modulation is reported in a patient with Ebstein anomaly and recurrent atrioventricular nodal re-entrant tachycardia. Typical signals were recorded during electrophysiological study at the slow pathway region between the His bundle and the coronary sinus where ablation was performed successfully. Thus, slow pathway modulation seems to be a safe procedure even in selected patients with Ebstein anomaly.

Multiple mechanisms of successful slow-pathway catheter ablation of common atrioventricular nodal re-entrant tachycardia.
BACKGROUND In patients with atrioventricular nodal re-entrant tachycardia, modifications of the antegrade atrioventricular nodal function curve caused by catheter ablation of the so-called slow pathway are heterogeneous, but have not yet been systematically evaluated. AIM To test the hypothesis that successful treatment is independent of specific electrophysiological modifications of atrioven...
متن کاملSuccessful ablation of atrioventricular nodal re-entrant tachycardia in a patient with interruption of inferior vena cava and azygos continuation.
Congenital anomalies of the venous system are a challenge for cardiac catheterization and radiofrequency ablation. This article describes ablation of atrioventricular nodal re-entrant tachycardia performed solely through the azygos continuation in a patient with inferior vena cava interruption.
متن کاملUnusual examples of supraventricular re-entrant tachycardias.
Programmed electrical stimulation of the heart uncovered unusual findings in four patients suffering from supraventricular tachycardias. They included 1) two supraventricular tachycardias of different location and frequency in the same patient, 2) increase in rate of a re-entrant atrioventricular (A-V) nodal tachycardia followed by the development of 2-to-1 A-V block, 3) a "gap" in A-V conducti...
متن کاملMechanisms of junctional tachycardia showing ventricular pre-excitation.
Over a period of five years 12 patients underwent electrophysiological studies for the investigation of recurrent tachycardias which showed ventricular pre-excitation. Nine patients had a type B pattern and two a type A. One patient had episodes of both types. Dual atrioventricular nodal pathways were found in six of seven patients with atrioventricular nodal re-entrant tachycardia mechanisms. ...
متن کاملRadiofrequency Catheter Ablation Of Atrioventricular Nodal Reentry Tachycardia In A Patient With Inferior Vena Cava Anomaly
Curative radiofrequency catheter modification of the slow pathway is the recommended therapy for patients suffering from recurrent symptomatic atrioventricular nodal reentry tachycardia. This is usually performed via femoral vein and the inferior vena cava (IVC). Presence of venous occlusion or complex venous anomaly involving the IVC may preclude this approach. Here, we report a case with a co...
