Niraj Sharma, MD, FHRS, Northside Hospital is joined by Rhea Pimentel, BChir, MD, FHRS, University of Kansas Health System and Usman Siddiqui, MD, Florida Cardiology Advent Health Systems, Orlando, to discuss how the FLUTFIB study aimed to assess the incidence, duration, timing, and symptoms of atrial fibrillation (AF) after cavotricuspid isthmus (CTI) ablation in patients with atrial flutter (AFL). The study included 100 patients with AFL, who received implantable loop recorders for continuous AF monitoring following CTI ablation. Over a median follow-up of 24 months, 77% of patients experienced AF episodes, typically occurring around 180 days post-ablation. Most AF episodes lasted over an hour, and about half of the patients reported symptoms. Baseline characteristics and risk scores (HATCH and CHA2DS2-VASc) did not predict AF development. Oral anticoagulation was discontinued in 32% of patients during follow-up but was restarted in 15% after AF detection. No strokes or transient ischemic attacks were recorded. This study, the largest of its kind, underscores the high incidence of often asymptomatic AF after AFL ablation and provides insights for anticoagulation management post-ablation.

Deepthy Varghese, MSN, ACNP, FNP, Northside Hospital is joined by Hung-Fat Tse, Sr., MD, University of Hong Kong and Glenn Young, MBBS, Royal Adelaide Hospital to discuss the effectiveness of the PRECISE-DAPT score with the CHA2DS2VASC score in predicting thromboembolic risk in nonvalvular atrial fibrillation (AF) patients undergoing transesophageal echocardiography (TEE) before AF ablation. 428 patients were analyzed, with 60 in the thrombogenic positive group and 368 in the thrombogenic milieu negative group. Multivariate logistic regression revealed that the PRECISE-DAPT score independently predicted thrombogenic milieu presence (OR: 1.145, CI: 1.083–1.211, p < 0.001). The study concluded that the PRECISE-DAPT score is a valuable predictor of thromboembolic risk in AF patients undergoing TEE before ablation procedures.

Deepthy Varghese, MSN, ACNP, FNP, Northside Hospital is joined by Sirena Bridges, MSN, FNP-BC, CCDS, VA Tennessee Valley Healthcare, and Jodie L. Hurwitz, MD, FHRS, North Texas Heart Center to discuss the effects of metoprolol and carvedilol on the risk of atrial tachyarrhythmia (ATA) and ventricular arrhythmia (VA) in over 4,000 heart failure (HF) patients with a primary prevention implantable cardioverter-defibrillator (ICD) by pooling data from five landmark ICD trials. Carvedilol treatment was associated with a 35% reduction in the risk of ATA and a corresponding decrease in the risk of inappropriate ICD shocks when compared to metoprolol. While there was a trend towards a lower risk of fast VA with carvedilol, this finding did not reach statistical significance. Carvedilol's unique properties, including its ability to block both β and α receptors, improve hemodynamics, and exhibit antiarrhythmic effects, may contribute to its superior outcomes. Overall, these results suggest that carvedilol may be preferred as the first-line beta-blocker choice in HF patients with a primary prevention ICD, but further prospective studies are needed to validate these findings and assess the impact of contemporary HF therapies on arrhythmic outcomes

Deepthy Varghese, MSN, ACNP, FNP, Northside Hospital is joined by Tina Baykaner, MD, MPH Stanford University, and Gurukripa N Kowlgi, MBBS, MSci, Mayo Clinic–Rochester to discuss; the multicenter study investigated the potential of machine learning (ML) models to improve risk stratification for implantable cardioverter-defibrillator (ICD) implantation in patients at risk of sudden cardiac death (SCD). By combining clinical variables with 12-lead electrocardiogram (ECG) time-series features, the models aimed to predict non-arrhythmic mortality within three years after device implantation. Results showed that ML models identified patients at risk with high accuracy, demonstrating robust performance in both the development and external validation cohorts. This suggests that ML-based approaches could enhance risk assessment for SCD prevention in primary prevention populations.

William H. Sauer, MD, FHRS, CCDS, Brigham and Women's Hospital is joined by Edward P. Gerstenfeld, MD, MS, FHRS, University of California, San Francisco, and Yasser Rodriguez, MBA, MD, Cleveland Clinic Florida to discuss;

Background: Premature ventricular complexes (PVCs) are common and associated with worse outcomes in patients with heart failure. Class 1C antiarrhythmic drugs (AADs) effectively suppress PVCs, but guidelines currently restrict their use in structural heart disease.

Conclusions: Class 1C AADs effectively suppressed PVCs in patients with NICM and ICDs, leading to increases in LVEF and biventricular pacing percentage. In this limited sample, their use was safe. Larger studies are needed to confirm the safety of this approach.

Deepthy Varghese, MSN, ACNP, FNP, Northside Hospital is joined by James O'Hara, PhD, PA, Virginia Heart, and Shunmuga Sundaram Ponnusamy, MBBS, MD, CEPS-A, Velammal Medical College Hospital, and Research Institute to discuss a study that evaluated the impact of QRS morphology on the risk of life-threatening ventricular arrhythmias in heart failure patients treated with cardiac resynchronization therapy with a defibrillator (CRT-D). The analysis included 2,862 patients from five major ICD trials, focusing on those with a QRS duration of ≥130 ms. Patients were categorized into those receiving ICD-only or CRT-D. Key findings: Among patients with left bundle branch block (LBBB), those with CRT-D showed a significant 44% reduction in the risk of fast ventricular tachycardia (VT)/ventricular fibrillation (VF) compared to ICD-only patients. They also had a lower fast VT/VF burden and fewer appropriate shocks. In patients with non-left bundle branch block (NLBBB), CRT-D did not reduce the risk of fast VT/VF and was associated with a significant increase in the burden of fast VT/VF events compared to ICD-only patients. The study concludes that CRT-D effectively reduces life-threatening ventricular arrhythmias in LBBB patients but may increase the risk in NLBBB patients.

Deepthy Varghese, MSN, ACNP, FNP, Northside Hospital is joined by Aarti Dalal, DO, FHRS, CEPS-P, Vanderbilt University and Peter S. Fischbach, MA, MD, Emory University/Children's Healthcare of Atlanta to discuss the multicenter, single-arm trial evaluated the safety and efficacy of transplacental treatment for fetal supraventricular tachycardia (SVT) and atrial flutter (AFL). The treatment involved using digoxin, sotalol, and flecainide for singleton pregnancies from 22 to less than 37 weeks of gestation with sustained fetal SVT or AFL with heart rates of at least 180 beats per minute. Out of the 50 enrolled patients, fetal tachyarrhythmia resolved in 89.8% of cases overall, and in 75.0% of cases where fetal hydrops were present. Pre-term births occurred in 20.4% of patients. Maternal adverse events were observed in 78.0% of patients, with serious adverse events leading to discontinuation of treatment in 4 patients. Two fetal deaths occurred due to heart failure, and neonatal tachyarrhythmia was observed in 31.9% of neonates within 2 weeks after birth. In conclusion, the transplacental treatment protocol was effective and tolerable in 90% of patients, but serious adverse events were noted in fetuses, and tachyarrhythmias could recur in neonates within the first 2 weeks after birth.

Premarket data showed high PVI durability during mandatory remapping studies. Data on lesion durability in real-world patients with clinically indicated redo procedures are scarce. In this episode of The Lead, we discuss why and how this study sought to report PVI durability rates in patients undergoing a clinically indicated redo procedure after an index PVI using PFA.

Deepthy Varghese, MSN, ACNP, FNP, Northside Hospital, is joined by Gregory Lip, MD., University of Liverpool, and Elaine Y. Wan, MD, FHRS Columbia University, Cardiology to discuss the limitations of current clinical decision tools for assessing bleeding risk in individuals with atrial fibrillation (AF) taking direct-acting oral anticoagulants (DOACs). Conducted as a secondary analysis of the RE-LY trial and validated in multiple cohorts, the study introduces the DOAC Score as a personalized risk assessment tool. The DOAC Score incorporates various covariates such as age, creatinine clearance, underweight status, medical history, and medication use to estimate the comparative risk for major bleeding. The risk prediction model demonstrated robust performance, outperforming the HAS-BLED score in terms of predictive accuracy. Internal and external validation in diverse cohorts, including the GARFIELD-AF registry, COMBINE-AF pooled clinical trial cohort, and administrative databases, confirmed the score's reliability in stratifying bleeding risk among individuals on different DOACs. The DOAC Score represents a significant advancement in tailoring risk assessments for bleeding in AF patients receiving DOAC therapy, contributing to more informed clinical decision-making.

However, the effect of CRT on long-term survival is not known. We randomly assigned patients with New York Heart Association (NYHA) class II or III heart failure, a left ventricular ejection fraction of 30% or less, and an intrinsic QRS duration of 120 msec or more (or a paced QRS duration of 200 msec or more) to receive either an ICD alone or a CRT defibrillator (CRT-D). We assessed long-term outcomes among patients at the eight highest-enrolling participating sites. The primary outcome was death from any cause; the secondary outcome was a composite of death from any cause, heart transplantation, or implantation of a ventricular assist device.

Deepthy Varghese, MSN, ACNP, FNP, of Northside Hospital, is joined by Dr. Mikhael F. El-Chami, MD, FHRS of Emory University, School of Medicine, and Dr. Rohit Mehta, MD, FHRS, with Advocate Health to discuss the study evaluated the preclinical performance and safety of retrieving chronically implanted dual-chamber leadless pacemakers (LPs). A total of 18 LPs were implanted in 9 ovine subjects, and after approximately 2 years, all LPs were successfully retrieved using a dedicated transvenous retrieval catheter. The retrieval procedure duration ranged from 2.5 to 36.4 minutes. Postretrieval analysis showed minimal tissue disruption at implant sites, and no significant device-related complications or injuries were observed. The study concludes that the retrieval of helix-fixation dual-chamber LP systems was safe and effective, paving the way for future clinical studies on LP retrieval.

Deepthy Varghese, MSN, ACNP, FNP, of Northside Hospital, is joined by guests Sandeep K. Goyal, MD, FHRS, Piedmont Heart Institute, and Andrea M. Russo, MD, FHRS, Cooper University Hospital. to discuss the article explores that development and validation of the HARMS2-AF score, a novel lifestyle risk assessment tool for identifying atrial fibrillation (AF) risk in the general population. Using data from the UK Biobank and Framingham Heart Study, the score, derived through Cox proportional hazards regression, includes variables like hypertension, age, body mass index, sex, sleep apnea, smoking, and alcohol. Physical inactivity and diabetes were not significant predictors. The score demonstrated effective predictive performance in both cohorts, outperforming existing models like Framingham-AF and ARIC, and comparable to CHARGE-AF. In conclusion, the HARMS2-AF score is a valuable tool for lifestyle-related AF risk identification, aiding in population screening and potential early intervention.

Deepthy Varghese, MSN, ACNP, FNP, of Northside Hospital, is joined by Sammy Khatib, MD, Ochsner Clinic, Foundation Program, and William Whang, MD, FHRS, Mount Sinai Hospital, to discuss the PULSED AF study investigated the impact of monitoring strategies on atrial arrhythmia (AA) recurrence after pulsed field ablation (PFA) in atrial fibrillation (AF) patients. The study employed various monitoring approaches, including 24-hour Holter monitoring and symptomatic trans telephonic monitoring, revealing that freedom from all AAs varied significantly based on monitoring strategy. PFA demonstrated substantial efficacy, yielding zero burden in 69.4% of paroxysmal AF and 62.2% of persistent AF patients, with a median burden below 9%. Notably, patients with PAF and less than 10% AA burden experienced clinically meaningful quality of life (QoL) improvements, while persistent AF patients showed QoL enhancements regardless of burden. The study suggests that the choice of monitoring protocol influences the ≥30-second AA recurrence endpoint and highlights the association between low AA burden post-PFA, improved QoL, and reduced healthcare utilization related to AAs. Notably, higher AA burden correlated with increased instances of repeat ablations and cardioversions.

Deepthy Varghese, MSN, ACNP, FNP, of Northside Hospital is joined by Dr. Matthew Kalscheur, MD, of the University of Wisconsin and Dr. Hawkins Gay, MD, MPH, of Northwestern University Feinberg School of Medicine discuss the study aimed to validate the use of artificial intelligence (AI) in identifying paroxysmal atrial fibrillation (AF) from 12-lead electrocardiograms (ECGs) in sinus rhythm (SR). The AI algorithm was trained on ECG data from a single center, including patients with and without AF. The dataset comprised 494,042 ECGs from 142,310 patients. Testing the model on the first ECG of each patient showed an accuracy of 78.1%, an area under the receiver-operating characteristic curve of 0.87, and an area under the precision-recall curve of 0.48. Performance varied with AF prevalence, demonstrating higher precision in high-risk groups (30% AF prevalence) and lower precision in low-risk groups (3% AF prevalence). The approach was robust when externally validated in another hospital. In conclusion, the AI-enabled ECG algorithm effectively identified paroxysmal AF in patients in sinus rhythm, showcasing potential clinical utility, particularly in high-risk populations.

Katz, MD, FHRS, of Morristown Medical Center and Victor Nauffal, MD, of Brigham and Women`s Hospital, to discuss the treatment options for high-risk Brugada syndrome (BrS) with recurrent ventricular fibrillation (VF) and how it is limited. Catheter ablation is increasingly performed, but a large study with long-term outcome data is lacking. We report the results of the multicenter, international BRAVO (Brugada Ablation of VF Substrate Ongoing Registry) for treatment of high-risk symptomatic BrS. Ablation treatment is safe and highly effective in preventing VF recurrence in high-risk BrS. Prospective studies are needed to determine whether it can be an alternative treatment to implantable cardioverter-defibrillator implantation for selected patients with BrS.

The study aimed to explore the relationship between the number of volunteer responders (VRs) arriving before Emergency Medical Services (EMS) and the likelihood of bystander cardiopulmonary resuscitation (CPR) and defibrillation during out-of-hospital cardiac arrests (OHCAs). The researchers analyzed OHCAs in two regions of Denmark and categorized them based on the arrival of VRs before EMS, with groups having 0, 1, 2, or 3 or more VRs. Using logistic regression adjusted for EMS response time, the study found that an increasing number of VRs arriving before EMS was associated with higher odds of bystander CPR and defibrillation. Specifically, the odds ratios (ORs) for bystander CPR and defibrillation increased as more VRs arrived before EMS, indicating a positive trend in the association. The study concluded that the presence of one or more VRs before EMS was linked to an increase in bystander CPR and defibrillation, with a notable trend towards increased defibrillation as the number of VRs increased.

Subclinical atrial fibrillation is short-lasting and asymptomatic and can usually be detected only by long-term continuous monitoring with pacemakers or defibrillators. Subclinical atrial fibrillation is associated with an increased risk of stroke by a factor of 2.5; however, treatment with oral anticoagulation is of uncertain benefit. Among patients with subclinical atrial fibrillation, apixaban resulted in a lower risk of stroke or systemic embolism than aspirin but a higher risk of major bleeding.

Sauer, MD, FHRS, CCDS, of Brigham and Women's Hospital is joined by guests Esseim Sharma, MD, of University Hospitals Cleveland, and Paul C Zei, MD, PhD, FHRS, of Brigham and Women's Hospital to discuss One-Year Outcomes Following Stereotactic Body Radiotherapy for Refractory Ventricular Tachycardia. Cardiac stereotactic body radiotherapy (SBRT) has emerged as a promising noninvasive treatment for refractory ventricular tachycardia (VT). The objective is to describe the safety and effectiveness of SBRT for VT in refractory to extensive ablation. For a select group of high-risk patients with VT refractory to standard therapy, SBRT is associated with a reduction of in VT and appropriate ICD therapies.

William H. Sauer, MD, FHRS, CCDS, of Brigham and Women's Hospital is joined by guests Sunil Kapur, MD, of Brigham and Women's Hospital, and Joshua M. Cooper, MD, FHRS, of Temple University Health System to discuss Intra-Pocket Ultrasound-Guided Axillary Vein Puncture vs. Cephalic Vein Cutdown for Cardiac Electronic Device Implantation: The ACCESS Trial. Intra-pocket ultrasound-guided axillary vein puncture (IPUS-AVP) for venous access in implantation of transvenous cardiac implantable electronic devices (CIED) is uncommon due to the lack of clinical evidence supporting this technique. This study investigated the efficacy and early complications of IPUS-AVP compared to the standard method using cephalic vein cutdown (CVC) for CIED implantation. IPUS-AVP is superior to CVC in terms of success rate, time to venous access, procedure duration, and radiation exposure. Complication rates were similar between the two groups. Intra-pocket ultrasound-guided axillary vein puncture should be a recommended venous access technique for CIED implantation.

Tedrow, MD, MS, FHRS, of Brigham and Women's Hospital, to discuss substrate mapping altering ventricular tachycardia inducibility. The authors performed a retrospective analysis of the reproducibility of programmed stimulation for the first induction of ventricular tachycardia in those with and without intervening voltage mapping. This was study was not randomized. All subjects had 2 rounds of programmed stimulation separated in time. One group underwent intracardiac echocardiographic mapping in between attempts while the other underwent substrate mapping. The authors found a change in the results of programed stimulation (to either a different VT, or to non-inducibility) more frequently after substrate mapping.

William H. Sauer, MD, FHRS, CCDS, of Brigham and Women's Hospital is joined by guests Bruce A. Koplan, MD, MPH, FHRS, and Victor Nauffal, MD, of Brigham and Women's Hospital, to discuss Procedure-Related Complications of Catheter Ablation for Atrial Fibrillation. In this study, online publication databases were searched for randomized trials that included patients undergoing a first ablation procedure of atrial fibrillation using either radiofrequency or cryoballoon. A total of 1,468 references were retrieved, of which 89 studies met the inclusion criteria, yielding a total of 15,701 patients included in the analysis. The reported overall and severe procedure-related complication rates were 4.51% and 2.44%, respectively. Vascular complications were the most frequent type of complication (1.31%). The next most common complications were pericardial effusion/tamponade (0.78%) and stroke/transient ischemic attack (0.17%). The procedure-related complication rate during the most recent 5-year period of publication was significantly lower than during the earlier 5-year period (3.77% vs 5.31%). The pooled mortality rate was stable over the 2 time periods (0.06% vs 0.05%). There was no significant difference in complication rate according to pattern of AF, ablation modality, or ablation strategies beyond pulmonary vein isolation. The authors conclude that procedure-related complications and mortality rates associated with catheter ablation of AF are low and have declined in the past decade.

Deepthy Varghese, MSN, ACNP, FNP, is joined by guests Martha G. Ferrara, DNP, FNP, FHRS, CCDS, and Dinesh Sharma, MD, MPH, FHRS, for a discussion of the accuracy of the Apple Watch for detection of AF. The Apple Watch (AW) irregular rhythm notification (IRN) feature uses photoplethysmography to identify prolonged episodes of irregular rhythm suggestive of atrial fibrillation (AF). IRN is FDA cleared for those with no previous history of AF, however, these devices are increasingly being used for AF management. The objective of the present study was to determine the accuracy of the IRN in subjects with a previous diagnosis of nonpermanent AF. In a population with known AF, the AW IRN had a low rate of false positive detections and high specificity. Sensitivity for detection by subject and by AF episode was lower. The current IRN algorithm appears accurate for AF screening as currently cleared, but increased sensitivity and wear times would be necessary for disease management.

William H. Sauer, MD, FHRS, CCDS, is joined by guests Jorge Romero, Jr., MD, FHRS, and Esseim Sharma, MD, for a discussion of the comparison of left bundle-branch area pacing to biventricular pacing in candidates for resynchronization therapy. This observational study included patients with LVEF≤35% who underwent biventricular or left bundle area pacing for the first time for Class I or II indications at 15 international centers. The primary outcome was the composite endpoint of time to death or heart failure hospitalization. Secondary outcomes included endpoints of death, HFH, and echocardiographic changes. Following implantation, LVEF improved from 27 to 41% with left bundle area pacing compared to an increase from 27 to 37% with biventricular pacing. On multivariable regression analysis, the primary outcome was significantly reduced with left bundle area pacing compared to biventricular pacing (20.8% vs 28%). The authors conclude that left bundle area pacing improved clinical outcomes, as observed in this study.

Jason T. Jacobson, MD, FHRS, is joined by guests Laurent Macle, MD, FHRS, and Peter M. Kistler, MBBS, PhD, FHRS, for a discussion of the Improved PAF Trial. Prior studies have demonstrated clinical benefits associated with cryoballoon pulmonary vein isolation (PVI) and concomitant posterior wall isolation (PWI) in patients with persistent atrial fibrillation (AF). However, the role for this approach in patients with paroxysmal atrial fibrillation (PAF) remains unclear. Compared with cryoballoon PVI, cryoballoon PVI+PWI appears to be associated with greater freedom from recurrent atrial arrhythmias and AF in patients with PAF during long-term follow-up >3 years.

William H. Sauer, MD, FHRS, CCDS, is joined by guests Nathaniel Steiger, MD, and Paul C. Zei, MD, PhD, FHRS, for a discussion on the PULSED AF Pivotal Trial. This was a prospective, global, multicenter, nonrandomized, paired single-arm study in which patients with paroxysmal (n=150) or persistent (n=150) symptomatic atrial fibrillation (AF) refractory to class I or III antiarrhythmic drugs were treated with pulsed field ablation. The results demonstrate similar efficacy compared with clinical studies evaluating radiofrequency ablation and cryothermal ablation. Safety with the new form of ablation technology appeared to be promising with no evidence of esophageal injury or phrenic nerve palsy observed.

The Lead Podcast - Episode 8 Jul 27, 2023

Andrew D. Krahn, MD, FHRS discusses this article with guests Jason D. Roberts, MD and Julia Cadrin-Tourigny, MD, PhD, CCDS. Clinical guidelines recommend regular screening for arrhythmogenic right ventricular cardiomyopathy (ARVC) to monitor at-risk relatives, resulting in a significant burden on clinical resources. Prioritizing relatives on their probability of developing definite ARVC may provide more efficient patient care.
