Percutaneous coronary intervention (PCI) has become the default therapy for obstructive coronary artery disease and invariably involves coronary stenting. Currently, stenting with a drug-eluting stent (DES) has become the default method for intervention, with few exceptions.1 The major drawback of this strategy is both acute and subacute stent thrombosis. The DES type, positioning, and lesion complexity may all contribute to stent thrombosis, the mechanisms of which are still under investigation.2 While there may be some debate as to the absolute occurrence of stent thrombosis, the complicatio...

Electrophysiology 2009: Making Practical Decisions in Difficult Economic Times

Guest Editor:
Todd J. Cohen, MD, FACC, FHRS

Electrophysiology continues to make advances. However, we have to place these advances in the context of an economy that has slipped into a deep recession (both in the United States and worldwide). For years, electrophysiology has seen double-digit growth in both the number of devices implanted as well as the number of catheter ablation procedures performed. This growth has been unprecedented and coincided with the growth seen on Wall Street and in technology over the past thirty years. As companies like Microsoft and Intel continued to grow and expand, so did the cardiovascular technology com...

ABSTRACT: Objectives. The present study was designed to delineate and compare the clinical characteristics of patients with apical and non-apical takotsubo syndrome in a high-volume U.S. hospital. Background. A comparison between apical and non-apical variants of the “broken heart,” or takotsubo syndrome, has not been performed in the United States. Methods. From 2004 through 2007, patients with takotsubo syndrome were identified according to the following criteria: acute chest pain with electrocardiographic changes or elevation of cardiac enzymes, absence of significant coronary narrowing...

In this issue of the Journal, Jabara et al1 provide an intriguing summary of differences between apical and non-apical Tako-tsubo syndrome based on case summaries of individuals with most often stress-induced ischemic events in the absence of major coronary vessel obstruction. The apical-type disorders are associated with larger defects, and not surprisingly, more severe complications. The apical patients probably show more intense ischemia with greater amounts of jeopardized muscle, and thus, the consequences of the ischemic insult are greater. Non-apical events appear more benign, presumably...

There have been major advances in the field of percutaneous coronary intervention (PCI) since its introduction 30 years ago. The improved safety and outcomes can be attributed to increasing operator experience, advances in device technology and the pivotal role of adjunctive pharmacotherapy. Despite these advances, challenges remain that require further research and development. One such challenge is the treatment of thrombotic lesions. Coronary artery thrombus commonly develops following rupture of an atherosclerotic plaque and undergoes modifications in terms of size and composition over tim...

In recent years, lead extraction has become an increasingly common procedure which has moved from the realm of cardiothoracic surgery to interventional cardiac electrophysiology. This article reviews indications for lead extraction and briefly discusses the common approaches currently employed to remove leads.

Indications

Several converging trends have driven the increase in lead extraction procedures. Twenty years ago, most patients needed to survive a cardiac arrest twice before implantable cardioverter-defibrillator (ICD) implantation would be considered. Today, most implantati...

Catheter Ablation for Atrial Fibrillation: An Attempt at Abating the Epidemic

The evolution of catheter ablation for atrial fibrillation. Over the past decade, atrial fibrillation ablation (AF) has evolved from an investigational therapy to one that many electrophysiologists have in their arsenal. Catheter ablation for AF originally attempted to recreate the Cox-Maze procedure by performing linear lesions in the atrium using radiofrequency or cryothermy. While this technique altered the atrial substrate, there was limited knowledge concerning the importance of the pulmonary veins in ...

ABSTRACT: This article highlights the major changes in the current procedural terminology codes (CPT codes) that were announced by the American Medical Association in January 2009. These new CPT codes were developed to more accurately reflect current cardiac device monitoring capabilities, long-distance telemetry and remote interrogation as well as follow-up practices. Some of these new code sets are structured differently than the CPT codes that they replace. Specifically, the new codes for remote monitoring do not have separate professional (-26) and technical components (-TC) applied to an ...
