Distribution Variance of Focal Atrial Tachycardia Foci and Long-Term Outcomes After Ablation. We aimed to evaluate age differences in foci and factors influencing recurrence after radiofrequency catheter ablation in adult and juvenile patients with FAT. After a mean follow-up of 47.2 months, FAT recurred in 57 patients.
Herein, we provide an overview of the current knowledge on the pathophysiology and risk factors for AF in adult congenital heart disease, with a special focus on the existing challenges in AF ablation. Emerging imaging modalities and ablation techniques might have a role to play.
ABSTRACT Introduction Atrial fibrillation (AF) is the most common arrhythmia, and atrioventricular (AV) node ablation with pacemaker implantation is a therapeutic option for refractory cases. However, AV node ablation in patients with bioprosthetic tricuspid valves poses technical challenges.
In Ebstein’s anomaly, there is downward or apical displacement of posterior and septal tricuspid leaflets. The anterior leaflet is not displaced, but is elongated to meet the other leaflets, so that when it closes, a loud sound, tricuspid sound, is produced, which is called as the sail sound.
Objective Tricuspid regurgitation (TR) is a progressive disease with high mortality and limited medical treatment options, and its association with atrial fibrillation (AF) has been documented. This study aimed to investigate whether successful rhythm control through catheter ablation for AF could reduce TR severity. of severe TR).
Atlantic Health System’s Morristown Medical Center Treats First Patient in New Jersey with Edwards’ EVOQUE Tricuspid Valve Replacement 3. Shorten the Blanking Period After Atrial Fibrillation Ablation, Experts Say 4. New Study Reveals 65 and Older Population Lowered Blood Pressure, Cholesterol and Weight Using Mobile Technology 2.
HPSD CTI ablation performed by EP trainees demonstrated a higher first-pass bidirectional isthmus block compared to the MPLD method. The aim of this study was to clarify the efficacy and safety of HPSD CTI-Abl performed by EP trainees and assess lesion characteristics between HPSD and moderate-power long duration (MPLD) ablations.
Catheter ablation (CA) of atriofascicular (AF) connections using irrigated RF can be challenging due to poor catheter stability and accessory pathway (AP) bumping at the tricuspid anulus (TA).
ABSTRACT Background Real-life data on efficacy and safety of pulsed-field ablation (PFA) using the pentaspline multi-electrode catheter in symptomatic atrial fibrillation (AF) patients is still scarce. Objective This study aims to assess the efficacy and safety of PFA in patients with persistent AF. Major complications occurred in 2.0%
Radiofrequency ablation (RFA) of cavotricuspid isthmus (CTI)dependent atrial flutter requires ablation of the tricuspid annulus overlying the right coronary artery (RCA). Although it is considered safe, reports of acute and subacute RCA injury in human and animal studies raise the possibility of late RCA stenosis.
Cavo-tricuspid isthmus (CTI) dependent atrial flutter (AFL) is one of the most common atrial arrhythmias involving the right atrium (RA). Radiofrequency catheter ablation has been widely used as a therapy of choice and it is curative.
m/s) bound by the right ventriculotomy, ventricular septal defect patch, and tricuspid and pulmonic valves. Historically, risk stratification electrophysiologic studies involved programmed ventricular stimulation with VT induction guiding implantable cardioverter-defibrillator (ICD) implantation or VT ablation.
Methods and Results This case report discusses a 65-year-old man who had previously undergone pulmonary vein isolation (PVI) and cavo-tricuspid isthmus ablation for atrial fibrillation before ASD closure, respectively. He developed atrial tachycardia (AT) and underwent catheter ablation.
Abstract Introduction Catheter ablation for atrial fibrillation (AF) reduces heart failure (HF) hospitalization in patients with HF with preserved ejection fraction (HFpEF). However, the long-term outcomes and subclinical HF after nonparoxysmal AF ablation in HFpEF patients have not been fully evaluated.
Recurrence rates after catheter ablation in these patients are high. Demographic, clinical, and outcome variables over 5 years were compared between patients with and without SVT recurrence.Results:Mean age of 25 patients (56% male) at time of SVT ablation was 31.5 ± 7.2 Ablation success rate was 92%.
BackgroundTypical isthmus-dependent atrial flutter (AFL) is traditionally treated through radiofrequency (RF) ablation to create a bidirectional conduction block across the cavo-tricuspid isthmus (CTI) in the right atrium.
Abstract Introduction Cavo-tricuspid isthmus (CTI) dependent atrial flutter (AFL) is one of the most common atrial arrhythmias involving the right atrium (RA) for which radiofrequency catheter ablation has been widely used as a therapy of choice. Follow-up echocardiographic data was available for 55 patients. to 50.4 ± 14.9%, p < .0001),
TR Options – H1 brought the FDA approvals of Edwards’ EVOQUE transcatheter tricuspid valve replacement system and Abbott’s TriClip tricuspid edge-to-edge repair (TEER) system, giving US interventionalists the options to repair or replace the tricuspid valve for the first time.
In contrast to other tachycardias, with atrial fibrillation (AF), the focus is often speculative, and ablation attempts are made accordingly. Pulmonary veins have been the primary target for ablation for many years, yet the success rates remain inconsistent. Implications for electrophysiologists. No published proof as such.
The earliest atrial activation site (EAAS) was at the right inferior septum, followed by the inferolateral wall of the tricuspid annulus. Ablation at the EAAS shifted it to the inferolateral wall. Methods and Results We report a case of fast-slow type AVNRT with two distinct atrial breakthrough sites during tachycardia.
Electrophysiologic study demonstrated 2 predominant PVC morphologies that were targeted with ablation, in addition to extensive abnormality with low-voltage and fractionated electrograms in the peri-tricuspid and right ventricular outflow tract free wall regions with septal sparing, suggestive of RV cardiomyopathy.
He had a history of slow pathway ablation for atrioventricular nodal reentrant tachycardia three months ago. The introduction of atrial extra-stimulus from the lateral tricuspid annular region during tachycardia terminated the tachycardia but recurred after one sinus beat (Figure 1).
Tricuspid atresia – ECG Right atrial overload is manifest as tall P waves in lead II and left ventricular hypertrophy with strain pattern is seen in lateral leads with tall R waves, ST segment depression and T wave inversion. All these features together in a cyanotic congenital heart disease is characteristic of tricuspid atresia.
Abstract Introduction Typical atrial flutter (AFL) is a macroreentrant tachycardia in which intracardiac conduction rotates counterclockwise around the tricuspid annulus. Methods This study enrolled 10 patients who underwent radiofrequency catheter ablation for a typical AFL.
ABSTRACT Background The impact of tricuspid regurgitation (TR) on the outcomes of pulmonary vein isolation (PVI) for atrial fibrillation (AF) remains unclear. This highlights the need for tailored ablation strategies that consider the RA substrate and/or TR treatment in patients with significant TR and AF.

Prior to CTI ablation, electrophysiological study and electro-anatomical mapping were performed, focusing on initiation and maintenance mechanisms of the arrhythmia.ResultsThe initiation of common atrial flutter takes place on the septal aspect of the cavo-tricuspid isthmus where functional unidirectional conduction block occurs.
