Debates and controversies about how to treat difficult problems or conditions abound in cardiac electrophysiology. This issue attempts to bring together a variety of controversial subjects and to present differing views on how to resolve these questions so clinicians will have a handy guide to the most current thinking about these difficult subjects.

This issue consists of 17 case studies, each involving a difficult decision that has to be made in the catheterization laboratory. Reading about the cases and seeing the ECGs will help cardiac electrophysiologists sharpen their clinical skills. The cases are also useful reading for those studying for board certification.

With over 6 million patients affected only in the United States, atrial fibrillation (AF) is a major health problem with profound effects on both the individual patient and society at large. In this issue of Heart Failure Clinics, we have focused on AF and tried to cover the most important and relevant aspects in a comprehensive and contemporary review. A distinguished group of experts and leaders in basic and experimental electrophysiology, epidemiology, clinical pharmacology, interventional clinical electrophysiology, and cardiac surgery contributed state-of-the-art reviews and also shared their insight to the future of AF. Topics include but are not limited to: Risk Factors and Genetics of Atrial Fibrillation; Mechanisms of Atrial Fibrillation: Rotors, Ionic Determinants, and Excitation Frequency; Diagnostic Evaluation and Follow-Up of Patients with Atrial Fibrillation; Catheter Ablation of Atrial Fibrillation; Antithrombotic and Anticoagulant Therapy for Atrial Fibrillation; Postoperative Atrial Fibrillation: Incidence, Mechanisms, and Clinical Correlates; and Novel Upstream Approaches to Prevent Atrial Fibrillation Perpetuation.

Controversies in Cardiac Electrophysiology are examined in this issue of Cardiac Electrophysiology Clinics. Difficult cases are presented and esteemed leaders in the field debate the pros and cons of various forms of management and treatment.

This issue of Cardiac Electrophysiology Clinics, Guest Edited by Drs. Suneet Mittal and David Slotwiner,, is dedicated to Device-Based Arrhythmia Monitoring. This is one of four issues selected each year by the series Consulting Editors, Ranjan K. Thakur and Andrea Natale. Topics include, but are not limited to: Implantable loop recorders, Permanent pacemakers and implantable cardioverter defibrillators, Heart failure monitoring, Remote programming and cybersecurity concerns, Models for remote monitoring, Data management and integration with EMR systems, Screening for atrial fibrillation and The role of artificial intelligence in arrhythmia monitoring.

Because atrial fibrillation promotes the formation of blood clots that can travel to the brain and block an artery, atrial fibrillation independently increases the risk of ischemic stroke four-to-five-fold. In this issue expert authors review drug therapies for stroke prevention, use of the new anticoagulants, ablation strategies for stroke prevention, LAA closure for stroke prevention, stroke in heart rhythm device patients, transesophageal echo in atrial fibrillation, and other topics important to the management of this serious complication.

This issue of Cardiac Electrophysiology Clinics covers arrhythmias in athletes, which can be a cause of morbidity and mortality. Expert authors review the most current information available about management of ventricular arrhythmias, atrial fibrillation, bradyarrhythmias, syncope and other conditions. Preparticipation screening, defibrillator use, and prevention are also discussed. Keep up-to-the-minute with the latest developments in this important aspect of cardiac electrophysiology practice.

This issue of Cardiac Electrophysiology Clinics examines Frontiers in Non-invasive Cardiac Mapping. Topics include imaging of heart rhythm disorders, experimental validation and modeling of validation, challenges and future directions of inverse problems, phase mapping of cardiac fibrillation, frequency domain analysis, analysis of diagnostic 12-lead electrocardiography and 3D non-invasive mapping, and many more.
