High-resolution/Density Mapping in Patients with Atrial and Ventricular Arrhythmias.

High-definition/ultra-high-definition mapping, owing to an impressive increase of the point density of electroanatomic maps, provides improved substrate characterization, better understanding of the arrhythmia mechanism, and a better selection of the ablation target in patients with atrial and ventricular arrhythmias. Despite the scarce comparative data on ablation results versus standard mapping, ultra-high-definition mapping is increasingly used by the electrophysiology community.


Impact of the type of electroanatomic mapping system on the incidence of cerebral embolism after radiofrequency catheter ablation of left atrial tachycardias.

Left atrial tachycardias (ATs) often occur after left atrial ablation. The incidence of symptomatic and silent cerebral embolism after radiofrequency catheter ablation of left ATs and the impact of the type of 3-dimesional electroanatomic mapping (3D-EAM) system on the incidence of cerebral embolism remain unclear.

Cryoballoon catheter ablation versus antiarrhythmic drugs as a first-line therapy for patients with paroxysmal atrial fibrillation: Rationale and design of the international Cryo-FIRST study.

Radiofrequency current (RFC) catheter ablation for patients with paroxysmal atrial fibrillation (AF) has been shown to be safe and effective in first-line therapy. Recent data demonstrates that RFC ablation provides better clinical outcomes compared to antiarrhythmic drug (AAD) in the treatment of early AF disease. Furthermore, studies comparing RFC and cryoballoon have established comparable efficacy and safety of pulmonary vein isolation (PVI) for patients with symptomatic paroxysmal AF.


Effect of cryoballoon ablation parameters on recurrence in patients with paroxysmal atrial fibrillation.

The aim of this research was to investigate the relationship between atrial fibrillation (AF) recurrence and second generation cryoballoon ablation (CBA) procedural parameters in patients with non-valvular paroxysmal AF (PAF).

Long-term impact of catheter ablation on arrhythmia burden in low-risk patients with paroxysmal atrial fibrillation: the CLOSE to CURE study.

Treatment of Atrial Fibrillation Using Ablation Index-Guided Contact Force Ablation: A Matching-Adjusted Indirect Comparison to Cryoballoon Ablation.

Ablation Index, also known as VISITAG SURPOINT™, is a novel lesion-quality marker that improves outcomes in radiofrequency (RF) catheter ablation of atrial fibrillation (AF). There is no direct evidence on the comparative effectiveness of RF ablation with Ablation Index and cryoballoon (CB). The objective of the present study was to conduct a matching-adjusted indirect comparison (MAIC) using individual patient-level data (IPD) to compare the effectiveness of RF ablation with Ablation Index to that of CB ...

Sustained Quality of Life Improvement Post-Cryoballoon Ablation in Patients with Paroxysmal Atrial Fibrillation: Results from the STOP-AF Post-Approval Study.

Pulmonary vein isolation by catheter ablation is a Class IA indication for the treatment of symptomatic, drug-refractory, paroxysmal atrial fibrillation (PAF). Quality of life (QoL) has been identified as a clinically meaningful endpoint but has not been comprehensively evaluated to date.

Value of Mapping and Ablation of Ventricular Tachycardia Targets within the Coronary Venous System in Patients with Non-ischemic Cardiomyopathy.

Patients with nonischemic cardiomyopathy (NICM) often require an epicardial ventricular tachycardia (VT) ablation procedures via subxiphoid access. The coronary venous system (CVS) provides limited access to the epicardial space OBJECTIVE: The purpose of this study was to determine the value of an approach targeting the CVS in these patients METHODS: In a series of 41 consecutive patients (age 59.7±11.5 years, 36 men [88%], ejection fraction 34.5±13.1%, 269 inducible VTs [6.6±5.0 VTs per patient]) with N...

Convergent ablation for persistent atrial fibrillation: Single center experience.

Endocardial catheter ablation has been shown to be effective in patients with paroxysmal atrial fibrillation (AF), and significantly less effective in patients with persistent AF (PAF). Lately, there is a trend toward a hybrid approach in the treatment of PAF that may be a more durable treatment for patients with PAF. In this manuscript we report our experience with the convergent ablation procedure in a PAF cohort.

Mapping of ventricular tachycardia in patients with ischemic cardiomyopathy: Current approaches and future perspectives.

Despite the technical improvements made in recent years, the overall long-term success rate of ventricular tachycardia (VT) ablation in patients with ischemic cardiomyopathy remains disappointing. This unsatisfactory situation has persisted even though several approaches to VT substrate ablation allow mapping and ablation of noninducible/nontolerated arrhythmias. The current substrate mapping methods present some shortcomings regarding the accurate definition of the true scar, the modality of detection in s...

Catheter Ablation of Ventricular Arrhythmia guided by a High-Density Grid Catheter.

Minimal data exists on the Advisor™ HD Grid (HDG) catheter and the Precision™ electroanatomic mapping system (EAM) for ventricular arrhythmia (VA) procedures. Using the HDG catheter the EAM uses the HD wave mapping and best duplicate software to compare the maximum peak-to-peak bipolar voltages within a small zone independent of wavefront direction and catheter orientation. The study aimed to summarise the procedural experience for VAs using the HDG catheter.

Historical Perspectives on Cardiac Mapping and Ablation.

Cardiac mapping has evolved from single point-by-point registration of cardiac electrical activity to its utmost real-time multimodality of mapping and imaging for catheter ablation of arrhythmias. The technology began with electrocardiogram recordings and evolved to the simultaneous registration of depolarization and repolarization using optical mapping and real-time multimodality imaging. Zero to near-zero fluoroscopy is currently used in practice to avoid radiation exposure. Real-time noninvasive mapping...

Fundamentals of Cardiac Mapping.

To characterize cardiac activity and arrhythmias, electrophysiologists can record the electrical activity of the heart in relation to its anatomy through a process called cardiac mapping (electroanatomic mapping, EAM). A solid understanding of the basic cardiac biopotentials, called electrograms, is imperative to construct and interpret the cardiac EAM correctly. There are several mapping approaches available to the electrophysiologist, each optimized for specific arrhythmia mechanisms. This article provide...

Hybrid Ventricular Tachycardia Ablation after Failed Percutaneous Endocardial and Epicardial Ablation.

Recurrent ventricular tachycardia (VT) after percutaneous ablation is associated with a high morbidity and mortality. We assessed the feasibility of open chest extracorporeal circulation (ECC)-supported 3D multielectrode mapping and targeted VT substrate ablation in patients with previously failed percutaneous endocardial and epicardial VT ablations.

Non-Fluoroscopic Radiofrequency Ablation of Left Atrial Appendage Tachycardia During Early Pregnancy.

Management of symptomatic atrial tachycardia (AT) during pregnancy seems challenging, especially those originating from left atrial appendage (LAA), which easily tend to be incessant and mediate cardiomyopathy. It's contradictory between therapy and pregnancy. In this study, we report a case of a woman who presented with persistent AT, which lead to heart failure, during early pregnancy. She underwent successful catheter ablation using CartoSound and electroanatomic mapping without fluoroscopy. An electroph...

Real-time Electrogram Analysis for Drivers of AtRial Fibrillation (RADAR): A Multi-Center FDA-IDE Clinical Trial of Persistent AF.

- Pulmonary vein isolation (PVI) is insufficient to treat all patients with persistent atrial fibrillation (AF), and effective adjunctive ablation strategies are needed. Ablation of AF drivers holds promise, but current technologies to identify drivers are limited by spatial resolution. In a single-arm, first-in-human, investigator-initiated FDA IDE study, we employed a novel system for real-time, high-resolution identification of AF drivers in persistent AF. - Persistent or longstanding persistent AF pati...

Dexmedetomidine Sedation for Paroxysmal Supraventricular Tachycardia Ablation Is Not Associated With Alteration of Arrhythmia Inducibility.

Dexmedetomidine (Dex) is an attractive agent for procedural sedation due to its unique pharmacodynamic profile, specifically affording predictable sedation without concurrent respiratory depression. However, Dex has previously been reported to prevent or terminate arrhythmias. The purpose of this study was to investigate paroxysmal supraventricular tachycardia (PSVT) inducibility and homeostatic stability during electrophysiology studies (EPSs) and ablation when a standardized Dex protocol was used as the p...

The Same is Not the Same: Device Effect during Bipolar Radiofrequency Ablation of Atrial Fibrillation.

 Different ablation devices deliver the same type of energy but use individual control mechanisms to estimate efficacy. We compared patient outcome after the application of radiofrequency ablation systems, using temperature- or resistance-control in paroxysmal and persistent atrial fibrillation (AF).

Cardioversion efficacy of nifekalan in patients with sustained atrial fibrillation after radiofrequency ablation.

To evaluate the efficacy and safety of nifekalan (NIF) on cardioversion in atrial fibrillation (AF) patients post radiofrequency ablation, and investigate the relevant factors related to the cardioversion efficacy of NIF. We screened patients with sustained AF rhythm after radiofrequency ablation between November 2016 and July 2018. Participants were treated with intravenous NIF 0.4 mg/kg within 5-10 minutes after ablation. We observed the adverse reaction, and monitored the rhythm, heart rate, QT interval...

High Predictive Value of Adenosine Provocation in Predicting Atrial Fibrillation Recurrence After Pulmonary Vein Isolation With Visually Guided Laser Balloon Compared With Radiofrequency Ablation.

We recently demonstrated that the acute reconnection rate detected with adenosine provocation test (APT) was significantly lower after pulmonary vein isolation (PVI) with visually guided laser balloon ablation (VGLB) than with RF ablation (RF). We evaluated the recurrence rate of atrial arrhythmias at 12 months after VGLB vs. RF and the significance of APT results for the outcome.Methods and Results:Fifty patients with paroxysmal AF were randomized to either RF or VGLB ablation in a 1 : 1 fashion. After...

Effect of Renal Denervation and Catheter Ablation vs Catheter Ablation Alone on Atrial Fibrillation Recurrence Among Patients With Paroxysmal Atrial Fibrillation and Hypertension: The ERADICATE-AF Randomized Clinical Trial.

Association of Left Atrial High-Resolution Late Gadolinium Enhancement on Cardiac Magnetic Resonance with Electrogram Abnormalities Beyond Voltage in Patients with Atrial Fibrillation.

- Conflicting data have been reported on the association of left atrial (LA) late gadolinium enhancement (LGE) with atrial voltage in patients with atrial fibrillation. The association of LGE with electrogram (EGM) fractionation and delay remains to be examined. We sought to examine the association between LA LGE on cardiac magnetic resonance (CMR) and EGM abnormalities in patients with atrial fibrillation (AF). - High-resolution LGE CMR was performed prior to EGM mapping and ablation in AF patients. CMR f...

Clinical and electrophysiological characteristics predicting the re-ablation outcome for atrial fibrillation patients.

Re-ablation has an important role in the control of recurrent atrial fibrillation (AF) post the first ablation. The present study was to report the outcome of AF re-ablation for patients who recurred after initial ablation, and to characterize the clinical and electrophysiological features predicting recurrence after redo ablation.

Successful ablation for premature ventricular contraction originating from moderator band of morphologic right ventricle in congenitally corrected transposition of great arteries.

A 54-year-old man with congenitally corrected transposition of great arteries (CCTGA) was referred to our hospital for palpitation. 24-hour Holter ECG showed frequent premature ventricular contraction (PVC) and we performed catheter ablation for this PVC. Pace-mapping was performed in morphologic right ventricle (RV) by transaortic approach. Perfect pace-map was achieved in morphologic RV midpart lateral and ablation at this site could eliminate the clinical PVC. After the ablation, by integrating ablation ...
