Paradoxical preexcitation following successful ablation of a concealed accessory pathway
Catheter ablation is an established curative treatment for accessory pathways (APs), but in spite of the great progress made in the diagnosis and treatment, there is limited knowledge of the underlying cellular pathophysiology that determines the different clinical presentations. The case presented highlights the complex presentation and properties of some APs that can be encountered at the tim...
متن کاملLocalization of the accessory pathway in ventricular preexcitation (WPW) by means of combined ECG and VCG recordings.
The noninvasive localization of the accessory pa thway (AP) responsible for ventricular preexcitation is helpful in the initial evaluation of patients with Wolff-Parkinson-White (WPW) syndrome. Recently, two groups of authors independently published new classifications derived from the correlation of 12-lead ECG with electrophysiologic studies. ~'2 Although these classifications allow a more pr...
متن کاملLocalizing the accessory pathway in ventricular preexcitation patients using a score based algorithm.
OBJECTIVES Clinical data was analyzed to find an efficient way to localize the accessory pathway in patients with ventricular preexcitation. METHODS The delta wave morphologies and ablation sites of 186 patients who underwent catheter ablation were analyzed and an algorithm ("locAP") to localize the accessory pathway was developed from the 84 data sets with a PQ interval ≤0.12s and a QRS widt...
متن کاملLinking in accessory pathways. Functional loss of antegrade preexcitation.
BACKGROUND Concealed retrograde activation has been proposed as a mechanism for antegrade conduction block in the bundle branches and atrioventricular accessory pathways. We studied this hypothesis (linking) in 10 patients with the Wolff-Parkinson-White syndrome in whom antegrade preexcitation could be persistently blocked by overdrive atrial pacing. METHODS AND RESULTS An atrial pacing proto...
متن کاملNodoventricular accessory pathways in PRKAG2-dependent familial preexcitation syndrome reveal a disorder in cardiac development.
BACKGROUND Familial preexcitation syndrome is linked to mutations in PRKAG2. Previous studies on the R302Q mutation have provided evidence for a remarkably high proportion of otherwise rare accessory pathways with atrioventricular (AV) node-like conduction properties (Mahaim fibers). Yet, histopathologic proof is still lacking. We aimed to provide such proof. METHODS AND RESULTS We retrospect...
