In this issue of Cardiac Electrophysiology Clinics, guest editor Dr. Matthew J. Daniels brings his considerable expertise to the topic of Left Atrial Appendage Occlusion. Top experts in the field discuss topics such as pre-cath laboratory planning for left atrial appendage occlusion: optional or essential; the case for intracardiac echo to guide left atrial appendage closure; follow-up imaging after left atrial appendage occlusion: something or nothing and for how long?; left atrial appendage closure: what the evidence does and does not reveal; and more. Contains 11 practice-oriented topics including the strengths and weaknesses of the LAA covering disc occluders; left atrial appendage occlusion strengths and weaknesses of the lobe-only occluder concept in theory and in practice; the strengths and weaknesses of left atrial appendage ligation or exclusion (LARIAT, AtriaClip, Surgical Suture); the future of LAAC—in 5, 10, and 20 years; and more. Provides in-depth clinical reviews on left atrial appendage occlusion, offering actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

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.

In this issue of Cardiac Electrophysiology Clinics, guest editors Drs. Emily Zeitler and Luigi Di Biase bring their considerable expertise to the topic of Case-Based Studies in Cardiac Electrophysiology. Top experts discuss various real-world cases in the field, including SVC tear; ICD extraction in LVAD patient; extraction and lead management in myotonic dystrophy; complex lead management decision making; extraction in patient with psLSVC; and more. - Contains 18 relevant, practice-oriented topics including multiple AF ablation cases; multiple pediatric/genetics EP cases; considerations for elective open extraction including debulking; lead management around structural heart interventions; and more. - Provides in-depth clinical reviews on case-based studies in cardiac electrophysiology, offering actionable insights for clinical practice. - Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

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 Interventional Cardiology Clinics, edited by Dr. Apostolos Tzikas, will cover several important elements of Left Atrial Appendage Closure. Articles in this issue include, but are not limited to: Ischemic stroke in atrial fibrillation; History of LAAO; Anatomy of the left atrial appendage, including implications for endocardial and epicardial device closure; Indications, patient selection and referral pathways for LAAO; CT for LAAO; The Watchman device; The Amplatzer Amulet device; and The current device landscape and future perspectives.

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.
