BACKGROUND Accessory navicular can become symptomatic in childhood, and in some cases, the condition is associated with progressive flattening of the longitudinal arch. Moreover, some severe, rigid flatfoot deformities are associated with an accessory navicular. We investigated the results of concomitant calcaneo-cuboid-cuneiform osteotomies (triple C) and the modified Kidner procedure for seve...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Conventional Accessory Pathway (AP) ablation is a straightforward approach with high success rates, but the fluoroscopy time significantly higher. Electroanatomical mapping systems (EMS), reduce time, anatomical reconstruction and activation prolong procedure time. The Fluoroscopy Integration Module (FIM) uses prereco...

INTRODUCTION New arrhythmias (NA) may appear late after accessory pathway (AP) ablation, but their relation to curative radiofrequency (RF) lesion is unknown. OBJECTIVE The aim of this study was to determine the prevalence and predictors for NA occurrence after AP ablation and to investigate pro-arrhythmic effect of RF. METHODS Total of 124 patients (88 males, mean age 43 +/- 14 years) with...

Coronary artery injury is a rare, but serious complication of ablation. To describe case in which left inferolateral accessory pathway (AP) targeted via the great cardiac vein (GCV) was complicated by subacute circumflex occlusion requiring drug eluting stent (DES). N/A A 62-year-old male with palpitations due to atrio-ventricular reciprocating tachycardia setting Wolff-Parkinson-White syndrome...

The incidence, mechanisms and sites of block of spontaneous termination of circus movement tachycardia (CMT) using an atrioventricular accessory pathway (AP) were analyzed in 24 consecutive patients (17 with Wolff-Parkinson-White syndrome and seven with a concealed AP) who were not ieceiving antiarrhythmic drugs. Spontaneous termination of tachycardia occurred in 10 patients (105 episodes). A r...

The heterotetrameric adaptor complex 1 (AP-1) and the monomeric Golgi-localized, ear-containing, Arfbinding (GGA) proteins are components of clathrin coats associated with the trans-Golgi network and endosomes. The carboxyl-terminal ear domains (or -adaptin ear (GAE) domains) of two -adaptin subunit isoforms of AP-1 and of the GGAs are structurally similar and bind to a common set of accessory ...

Reciprocating tachycardia in a patient with a leftsided atrioventricular accessory pathway (AP) (Kent bundle, type A) capable only of ventriculo-atrial (V-A) transmission is described. The V-A AP is established as an essential link of the tachycardia circuit, as evidenced by : 1) retrograde atrial activation of the left atrium (LA) 60 msec or more before the low and high right atrium during rec...

BACKGROUND Accessory pathway (AP) ablation is not always easy. Our purpose was to assess the age-related prevalence of AP location, electrophysiological and prognostic data according to this location. METHODS Electrophysiologic study (EPS) was performed in 994 patients for a pre-excitation syndrome. AP location was determined on a 12 lead ECG during atrial pacing at maximal preexcitation and ...

BACKGROUND Differentiation between ventriculoatrial (VA) conduction over an accessory AV pathway (AP) and the AV node (AVN) may be difficult, especially in patients with a septal AP. METHODS AND RESULTS A new pacing method, para-Hisian pacing, was tested in 149 patients with AP and 53 patients without AP who had AV nodal reentrant tachycardia (AVNRT). Ventricular pacing was performed adjacent...

OBJECTIVES The purpose of this study was to categorize the reasons for a prolonged or failed procedure in a series of patients undergoing catheter ablation of an accessory pathway. BACKGROUND Radiofrequency ablation of accessory pathways at times requires a lengthy procedure or a second ablation session, or both, and not prior studies have systematically investigated the reasons for this. M...
