The Lead Podcast presented by Heart Rhythm Society

Description:
In this episode of The Lead, host Jason T. Jacobson, MD, FHRS, is joined by Sei Iwai, MD, FHRS, and Jeanne E. Poole, MD, FHRS, CCDS, to discuss "Cardiovascular Magnetic Resonance to Guide Defibrillator Implantation for LVEF of 36% to 50%: The CMR GUIDE Randomized Clinical Trial." The panel examines the trial's findings on using cardiovascular magnetic resonance–identified myocardial scar to guide primary prevention ICD implantation, including limitations of the study and current approaches to sudden cardiac death risk stratification, as well as the potential role of more sophisticated, dynamic risk-prediction models.
Learning Objectives:
Describe the design, patient population, primary outcome, and key findings of the CMR GUIDE randomized clinical trial.

Evaluate the limitations of using cardiovascular magnetic resonance–identified myocardial scar to guide primary prevention ICD implantation in patients with an LVEF of 36% to 50%.

Assess current challenges and emerging approaches to sudden cardiac death risk stratification, including the potential use of multimodal and dynamic risk-prediction models.

In this episode of The Lead, host Cinzia Monaco, MD, PhD, is joined by Kinan Kneizeh, MD,  and Konstantinos Vlachos, MD, PhD, to discuss "Pulsed Field Ablation Versus Sham to Treat Atrial Fibrillation: The PFA-SHAM Randomized Clinical Trial." The panel examines the trial's sham-controlled evidence for the effects of pulsed field ablation on atrial fibrillation recurrence, quality of life, AF burden, and psychological well-being, while considering placebo effects, study limitations, and the applicability of the findings to clinical practice.
Learning Objectives: 
1. Describe the design, patient population, endpoints, and key findings of the PFA-SHAM randomized clinical trial.
2. Evaluate the effects of pulsed field ablation compared with a sham procedure on atrial fibrillation recurrence, AF burden, quality of life, and psychological well-being.
3. Assess the trial's limitations, potential placebo effects, and applicability to the management of patients with symptomatic atrial fibrillation.
