Describes best practices in Ventricular Tachycardia and Fibrillation Ablation based on a consensus of the world's leading experts, based on the annual 'Venice Arrythmias' meeting. Catheter ablation of atrial fibrillation has become a widespread, yet controversial, treatment modality in electrophysiology laboratories. Presents a comprehensive and up-to-date overview of all the most important and debated aspects of atrial fibrillation ablation. Covers all key topics, from pre- and intra-procedural management to best techniques and outcomes for patients with and without structural HD to Indications for VT/VF ablation and hybrid therapy to future tools and treatment options.
In recent years, catheter ablation of atrial fibrillation has become a widespread treatment modality in electrophysiology laboratories all over the world. Nevertheless, many aspects of the therapy are controversial. Developed by world-renowned experts in the field, this book presents a comprehensive and up-to date overview of all the most important and debated aspects of atrial fibrillation ablation, including: • Ablation techniques and technologies • Procedural endpoints • Patient management pre-, peri- and post-ablation • Anticoagulation issues • Prevention and treatment of complications • Definition of success and long-term results The text expands upon the content of the VeniceChart international consensus document on atrial fibrillation ablation and is enriched by several explanatory figures and tables. It provides a highly valuable source of information not only for researchers and specialists in electrophysiology, but also for general cardiologists, internists, fellows in cardiology and medical students.
The first practical, user-friendly guide to the theory and practice of a routinely used technique, this new manual provides the specialist in training with a thorough grounding in the equipment, procedures, and clinical findings with which clinicians need to be familiar. Conceived as an alternative to the large and expensive texts aimed at specialists, the handbook is divided into two sections, which present: a review of the main kinds of arrhythmia, with illustrations of typical ECG findings supported where appropriate by correlative imaging the principal diagnostic and therapeutic procedures, including implantation of pacemakers, resynchronization therapy, use and placement of catheters and ablation techniques Providing practical guidance on clinical applications, and illustrated with numerous graphics, checklists and flowcharts to enable readers to locate information quickly and easily, Handbook of Cardiac Electrophysiology is an accessible resource covering a widespread, but complex technology.
The first comprehensive resource on transseptal catheterization.Although the transseptal technique was described half a century ago, it has remained essentially unchanged. Recent advances in cardiac electrophysiology and left heart interventions have led to renewed interest in the technique as a means of delivering modern therapeutic interventions.Until now, the knowledge required for safely gaining access to the left atrium to perform catheter ablation for atrial fibrillation or other interventions has existed only in original publications and review articles. This textbook brings all of the relevant information about this technique under one cover, with top experts in each area addressing anatomy, indications, transseptal puncture, visualization technologies, interventional devices, challenging cases, complications, and emerging tools. Electrophysiologists and interventional cardiologists will find Transseptal Catheterization and Interventions invaluable for their work. For teachers and trainees, it will be a welcome teaching tool and resource.
This issue of Cardiac Electrophysiology Clinics devoted to syncope a disorder that is associated with increased mortality. Internationally recognized experts discuss the many causes of syncope, helping the clinician to distinguish life-threatening etiologies from benign ones.
This issue of the Cardiology Clinics, edited by Ranjan K. Thakur, Andrea Natale, and Ziyad Hijazi, focuses on Cardioembolic Stroke. Topics covered in this issue include, but are not limited to: epidemiology of atrial fibrillation and stroke, atrial fibrillation and stroke, device detected atrial fibrillation, left atrial appendage closure for stroke prevention, cryptogenic strokes, and atrial fibrillation and cognitive decline.
Implantable defibrillators as originally conceived by Michel Mirowski were limited to the detection and automatic termination of ventricular fibrillation. In the original "AID" device, the detection algoritlun sought to distinguish sinus rhytlun from ventricular fibrillation by identifying the "more sinusoidal waveform of ventricular fibrillation. " The therapeutic intervention was elicited only once deadly polymorphic rhythms had developed. It was rapidly learned, however, that ventricular fibrillation is usually preceded by ventricular tachycardia. Mirowski recognized the pivotal importance of developing algoritllms based on heart rate. Ventricular tachycardia detection allowed the successful development of interventions for the termination of ventricular tachyarrhythmias before they degenerated into ventricular fibrillation. Current device therapy no longer confines itself to tlle termination of chaotic rhythms but seeks to prevent them. Diagnostic algorithms moved upward along the chain of events leading to catastrophic rhytlulls. Rate smoothing algorithms were developed to prevent postextrasystolic pauses from triggering ventricular and atrial tachyarrhytlmlias. Beyond the renaissance of ectopy-centered strategies, long-term prevention received increasing attention. Multisite pacing therapies provided by "Arrhythmia Management Devices" were designed to reduce the "arrhytlunia burden" and optimize the synergy of cardiac contraction and relaxation. Clinical evidence now suggests that atrial fibrillation prevention by pacing is feasible and tllat biventricular pacing may be of benefit in selected patients with heart failure. However, these applications of device therapy that generally require ventricular defibrillation backup remain investigational and were not considered in this book.

The importance of social media as a way to monitor an electoral campaign is well established. Day-by-day, hour-by-hour evaluation of the evolution of online ideas and opinion allows observers and scholars to monitor trends and momentum in public opinion well before traditional polls. However, there are difficulties in recording and analyzing often brief, unverified comments while the unequal age, gender, social and racial representation among social media users can produce inaccurate forecasts of final polls. Reviewing the different techniques employed using social media to nowcast and forecast elections, this book assesses its achievements and limitations while presenting a new technique of "sentiment analysis" to improve upon them. The authors carry out a meta-analysis of the existing literature to show the conditions under which social media-based electoral forecasts prove most accurate while new case studies from France, the United States and Italy demonstrate how much more accurate "sentiment analysis" can prove.
Heart disease is currently the leading cause of maternal mortality in developed countries and is expected to increase further due to advanced maternal age and conditions such as type 2 diabetes. Maternal Cardiac Care: A Guide to Managing Pregnant Women with Heart Disease is an up-to-date, multidisciplinary resource for physicians and advanced practice nurses caring for pregnant patients with a variety of preexisting and emerging cardiac issues. - Offers comprehensive information on caring for women with heart disease, in an easy-to-follow, quick-access format. - Shares knowledge from a multidisciplinary group of experts who are well versed in the team approach needed to treat this high-risk patient population. - Includes extensive references for readers who want to delve more deeply into specific subjects. - Ideal for obstetricians, internists, cardiologists, critical care specialists, and advanced practice nurses involved in caring for pregnant patients, as well as institutions and departments that need detailed guidance on establishing a maternal cardiac care program.
