چکیده
Figure 1 Electroanatomic activation map during RA stimulation (A) before and (B) after MAP ablation. Signals obtained at the ablation catheter located at the free lateral wall are shown. MAP anatomical disposition (yellow dots). Right bundle branch anatomical disposition (blue dots). M =mahaim accessory pathway potential; MAPd = distal ablation catheter recording; MAPp = proximal ablation catheter recording; RV = right ventricle; TA = tricuspid anulus; V1 and V6 = electrocardiographic lead recordings.

Successful ablation of coexistent Mahaim tachycardia and right posterior accessory pathway in a patient with Ebstein's anomaly.
The atriofascicular accessory pathway (AP), known as the Mahaim pathway, is a rare form of pre-excitation, comprising less than 3% of all APs. Mahaim AP is characterized by decremental, anterograde-only conduction, and antidromic tachycardia with left bundle branch morphology. Prevalence of Mahaim AP in Ebstein's anomaly is significantly high. In addition, combination of Wolff-Parkinson-White (...
متن کاملRadiofrequency catheter ablation of Mahaim tachycardia by targeting Mahaim potentials at the tricuspid annulus.
BACKGROUND Reentrant tachycardias associated with Mahaim pathways are rare but potentially troublesome. Various electrophysiological substrates have been postulated and catheter ablation at several sites has been described. OBJECTIVE To assess the efficacy and feasibility of targeting discrete Mahaim potentials recorded on the tricuspid annulus for the delivery of radiofrequency energy in the...
متن کاملRadiofrequency catheter ablation of Mahaim fibers at the tricuspid annulus.
BACKGROUND The purpose of this study was to test the feasibility of radiofrequency catheter ablation of Mahaim fibers at the tricuspid annulus. METHODS AND RESULTS Four patients who fulfilled criteria for having Mahaim fibers and preexcited reciprocating tachycardia underwent radiofrequency catheter ablation. Three patients had atriofascicular connections, and one patient had an atrioventricu...
متن کاملMahaim Fibre Tachycardia: Recognition and Management
Introduction Dr. Gallagher et al1 wrote 22 years ago that "the role of Mahaim fibers in the genesis of cardiac arrhythmias in man has been controversial since they were first described " in the late 30's by Dr. Ivan Mahaim2. The very early reports were strictly anatomical studies2-6. This histopathologic quest did not end yet. Mahaim fibers were supposed to be accessory connections taking off f...
متن کاملHistorical notes and classification of the variants of ventricular preexcitation
Almost 25 years ago, Gallagher et al. [1] stated that “the role of Mahaim fibers in the genesis of cardiac arrhythmias in man has been controversial since they were first described.’’The original description of these fibers was made by Ivan Mahaim in the late 1930s [2, 3] (Fig. 1.1). He found a conducting tissue extending from the atrioventricular (AV) node to the ventricular myocardium. There ...
