anteroseptal pathways ablation

R A Santilli, D Caivano, R Pariaut, F Birettoni, M Perego, F Porciello, N S Moïse
In humans, accessory pathways (APs) in an anteroseptal and midseptal position are often challenging to ablate because of their close proximity with the conduction pathways of the atrioventricular junction. The use of low-energy ablation techniques can be useful to reduce the risk of permanently damaging the atrioventricular node and the His bundle. This report describes the use of low-energy radiofrequency catheter ablation to successfully and permanently ablate anteroseptal APs in two dogs with orthodromic atrioventricular reciprocating tachycardia...

BACKGROUND: There remains some confusion delineating the accurate location and the detailed anatomical relationship between atrioventricular accessory pathways (APs) located in the superoparaseptal region. OBJECTIVE: The purpose of this article was to detail the anatomical relationship and accurate location of APs located in the superoparaseptal region. METHODS: Between May 2009 and November 2016, 11 patients with superoparaseptal APs (SPS-APs) were identified in 129 consecutive patients who underwent catheter ablation for APs in our center...

BACKGROUND: Dedicated mapping studies of the triangle of Koch to characterize retrograde fast pathway activation have not been previously performed using high-resolution, 3-dimensional, multielectrode mapping technology. OBJECTIVE: To delineate the activation pattern and spatial distribution of the retrograde fast pathway within the triangle of Koch during typical atrioventricular nodal reentrant tachycardia (AVNRT) and right ventricular pacing in a consecutive series of patients using the Rhythmia mapping system (Boston Scientific, Natick, MA)...

Data regarding catheter ablation of anteroseptal accessory pathways through the aortic cusps are limited. We describe two cases of true para-Hisian accessory pathways successfully ablated from the aortic cusps (right coronary cusp and non-coronary cusp, respectively) along with a review of the current literature. Due to the close proximity to the atrioventricular node and the high risk of complication, mapping of the aortic cusps should always be considered in the case of anteroseptal accessory pathways. Anteroseptal accessory pathways can be safely and effectively ablated from the aortic cusps with good long-term outcomes...

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 confirmed at intracardiac EPS in 494 patients. RESULTS: AP location was classified as anteroseptal (AS)(96), right lateral (RL)(54), posteroseptal (PS)(459), left lateral (LL)(363), nodoventricular (NV)(22)...

PURPOSE: The aim of this study was to investigate the accuracy of three algorithms in predicting accessory pathway locations in adult patients with Wolff-Parkinson-White syndrome in Turkish population. METHODS: A total of 207 adult patients with Wolff-Parkinson-White syndrome were retrospectively analyzed. The most preexcited 12-lead electrocardiogram in sinus rhythm was used for analysis. Two investigators blinded to the patient data used three algorithms for prediction of accessory pathway location...

INTRODUCTION: Anteroseptal accessory pathways (APs) are located in the apex of the triangle of Koch's connecting the atrial and ventricular septum in the region of the His bundle. Ablation of anteroseptal pathway locations remains a challenge to the electrophysiologist due to a very high risk of transiet or permanent atrioventricular (AV) block. CASE REPORT: A male, 18-year-old, patient was hospitalized due to radiofrequency (RF) ablation of APs. He was an active football player with frequent palpitations during efforts accompanied by dyspnea and lightheadedness, but without syncope...

BACKGROUND: Fluoroscopic catheter ablation of cardiac arrhythmias in pediatric patients exposes the patients to the potential risk of radiation considering the sensitivity of this population and its longer life expectancy. We evaluated the feasibility, safety, and efficacy of accessory pathway (AP) ablation guided by CARTO3 electroanatomic mapping (EAM) system with both cryoenergy and radiofrequency (RF) energy in order to avoid x-ray exposure in pediatric patients. METHODS: We included 44 patients (mean age: 13...

BACKGROUND: Radiofrequency catheter ablations of anteroseptal (AS) accessory pathways (AP) in pediatric patients have higher incidence of atrioventricular (AV) block than other AP locations. We report our experience using cryoablation in pediatric patients where a His bundle electrogram was noted on the ablation catheter at the site of the successful ablation. METHODS AND RESULTS: We retrospectively reviewed all patients ≤21 years that underwent cryoablation for an AS AP from 2005 to 2012 at our institution (n=70)...

AIMS: Radiofrequency catheter ablation (RFCA) is well established as a definitive therapy of accessory pathways (APs). Successful RFCA of anteroseptal APs at the non-coronary cusp (NCC) have been reported in several case reports. We aimed to evaluate the prevalence, safety, efficacy, and long-term outcome of RFCA at the NCC for the treatment of para-hisian APs. METHODS AND RESULTS: Our study included 17 patients (58.8% female, mean age 46.9 ± 15.9 years) with para-hisian APs...

BACKGROUND: Radiofrequency (RF) catheter ablation in the septal arrhythmia substrates has an increased risk of irreversible atrioventricular block. Despite its safety profile, several studies reported a lower acute success rate and a higher recurrence rate with cryoablation of septal accessory pathways (APs) when compared to RF ablation. The aim of this study was to assess the efficacy and safety of cryoablation of right septal APs using an electroanatomical mapping system guidance. METHODS AND RESULTS: A total of 43 consecutive patients (13...

AIMS: Unlike in the Wolff-Parkinson-White syndrome, there has been no systematic study on the role of the pre-excitation pattern in predicting the ablation site in patients with atriofascicular (AF) pathways. We assessed in a large cohort the value of the 12-lead electrocardiogram (ECG) during antidromic tachycardia (ADT) to predict the site of ablation. METHODS AND RESULTS: Forty-five patients were studied, 23 males (51%), mean age of 27 ± 12 years with 46 AF pathways and 48 ADT using the AF pathway for A-V conduction...

BACKGROUND: Differentiation between atrioventricular nodal reentry tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) can be sometimes challenging. Apical right ventricular (RV) entrainment can help in differentiation; however, it has some fallacies. We thought to compare the accuracy of anteroseptal basal RV entrainment to RV apical entrainment in identifying the mechanism of supraventricular tachycardia (SVT). METHODS: Forty-two consecutive patients with SVT who underwent catheter ablation were prospectively studied...

Anteroseptal accessory pathways are relatively rare. Because of the close proximity of the atrioventricular (AV) node, ablation of these accessory pathways has the potential to result in AV block. The anteroseptal region is adjacent to the noncoronary cusp, allowing anteroseptal accessory pathways to be ablated from the noncoronary cusp. A 34 year-old male patient with recurrent episodes of palpitation for approximately ten years was admitted to our department. Twelve lead-ECG was consistent with anteroseptal accessory pathway...
