Catheter ablation (CA) is a highly effective therapy for the treatment of paroxysmal atrial fibrillation (AF) when compared with antiarrhythmic drug (ADT). No randomized studies have two strategies in persistent AF. The present trial aimed to compare effectiveness CA vs. ADT treating Patients AF were randomly assigned or (excluding patients long-standing AF). Primary endpoint at 12-month follow-up was defined as any episode flutter lasting >24 h that occurred after 3-month blanking period....
BackgroundA high percentage of biventricular (BiV) or left ventricular (LV) pacing in cardiac resynchronization therapy (CRT) devices has been associated with superior clinical outcomes. However, the percent (%V) reported by CRT simply indicates number paces device delivered and not proportion that captured LV effectively.ObjectiveThe purpose this study was to determine whether a beat-by-beat evaluation effective would provide more accurate delivery.MethodsAn automatic electrogram...
Ultrasound guidance for vascular cannulation seems safer and more effective than an anatomical landmark approach, though it has not gained widespread support partly due to workflow interference of wired probes. A wireless ultrasound transducer (WUST) may overcome this issue. We report the effectiveness, time consumption, safety first-in-human experience in axillary vein guided with a novel WUST implantation cardiovascular implantable electric devices (CIEDs).After one-month training period,...
AimsThe aim of this study was to determine the acute and long-term outcome radiofrequency catheter ablation (RFCA) for cavotricuspid isthmus-dependent atrial flutter (CTI-AFL) in adults with without previous cardiac surgery (PCS), predictors these outcomes. Structural alterations anatomical substrate CTI-AFL are observed post-operative patients, may have an impact on success long-term.
Background: The hOLter for Efficacy analysis (OLE) study demonstrated that current device pacing diagnostics overestimate the amount of cardiac resynchronization therapy (CRT) effectively stimulates tissue. Sub-optimal increases mortality, hospitalizations, and associated health-care costs. We sought to estimate expected number hospital admissions due heart failure (HF) its respective financial impact in patients with maximized effective versus conventional pacing. Methods: A Markov model...
Critical isthmuses of atypical atrial flutters (AAFLs) are usually located at slow conduction areas that exhibit fractionated electrograms. We tested a novel software, intended for integration with commercially available navigation system, automatically detects electrograms, to identify the critical isthmus in patients AAFL ablation.All were analyzed; 27 33 AAFLs included. The PentaRay NAV catheter (Biosense Webster) was used mapping. software retrospectively applied; points duration ≥80 ms...
Unstable reentrant atrial tachycardias (ATs) (i.e., those with frequent circuit modification or conversion to fibrillation) are challenging ablate. We tested a strategy achieve arrhythmia stabilization into mappable stable ATs based on the detection and ablation of rotors.All consecutive patients from May 2017 December 2019 were included. Mapping was performed using conventional high-density mapping catheters (IntellaMap ORION, PentaRay NAV, Advisor HD Grid). Rotors subjectively identified...
A 29-year-old patient diagnosed with (S,L,L) congenitally corrected transposition of great arteries (CCTGA) and pre-excitation is presented. We performed a coronary angiogram it documented …
Background Different types of ventricular arrhythmias (monomorphic tachycardia [VT], polymorphic VT, or fibrillation) can be detected by implantable cardiac defibrillators (ICDs) in fast VT zone. The efficacy antitachycardia pacing (ATP) depends on the type treated arrhythmia. We hypothesized that an automatic algorithm based morphological affinity ICD far‐field electrograms during predict ATP success and need shock. Methods was evaluated recorded CareLink remote monitoring system (Medtronic...
Cardiac resynchronization therapy has demonstrated important benefits for selected patients suffering from heart failure. Those include clinical and/or echocardiography assessed improvement, as well hospitalizations and all-cause mortality reduction. However, about 30% of do not benefit the therapy. Suboptimal left ventricle lead position, post-implant dislodgements undesired phrenic nerve stimulation are potential causes responding it is always possible to avoid them during implant...
Purpose: A high percentage of bi-ventricular or left ventricular (LV) pacing in CRT devices has been associated with superior long-term clinical outcomes. However, the % (V) reported by only indicates number paces device delivered, not how many have electrically activated LV myocardium. beat-by-beat evaluation effective would provide a more accurate delivery and help avoid paced beats that do capture. Methods: We developed validated an automatic device-based algorithm to classify each pace...
