In collaboration with the Consulting Editors, Ranjan K. Thakur and Andrea Natale, Drs. Dhanunjaya Lakkireddy, David R. Holmes Jr., and Saibal Kar have assembled an issue of Cardiac Electrophysiology Clinics on Left Atrial Appendage. Topics include, but are not limited to, why we have an atrial appendage, thromboembolism in AF, role of LAA in systemic homeostasis, history of LAA closure, impact of LAA closure on systemic thromboembolization, perirprocedural imaging, anatomical considerations for epicardial and endocardial appendage closure, epicardial vs endocardial closure, technical considerations of endocardial and epicardial closure, surgical LAA occlusion, post procedural management, AF patients undergoing ablation, and more.

This issue explores the genetic basis of specific cardiomyopathies and phenotypic components of heart failure with an eye to the clinical implications of this genetic knowledge. An understanding of the genetic causes of disease can aid in development of effective prevention and management strategies.

The breadth and range of the topics covered, and the consistent organization of each chapter, give you simple but detailed access to information on anatomy, diagnostic criteria, differential diagnosis, mapping, and ablation. the book includes a unique section on troubleshooting difficult cases for each arrhythmia, and the use of tables, illustrations, and high-quality figures is unmatched among publications in the field.

This issue of Cardiac Electrophysiology Clinics, Guest Edited by Drs. Giuseppe Bagliani, Roberto De Ponti, and Fabio Leonelli is dedicated to The Complex World of Cardiac Pre-Excitation: towards Precision Electrocardiology. 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, Anatomy of the AV junction, Pre-excitation, Algorithms to identify accessory pathways location on 12-lead ECG, Pathophysiology of accessory pathways-mediated arrhythmias, Arrhythmias with by-stander accessory pathways, Arrhythmias involving unusual accessory pathways, Sudden cardiac death in patients with ventricular pre-excitation, Clinical approach to symptomatic and asymptomatic patients with ventricular pre-excitation, Methodology of accessory pathway ablation, Ablation of accessory pathways with unusual anatomic location, Ablation of accessory pathways with uncommon electrophysiologic properties, and Ablation in pediatric patients and in association with congenital heart disease.

This issue is a valuable tool to help electrophysiologists interpret complex ECGs so they can better understand arrhythmia mechanisms. Organized by cases, this issue illustrates many of the classic electrocardiographic findings and phenomena that every electrophysiologist should know. Study of this issue demonstrates a systematic way to analyze arrhythmia mechanisms.
