Racial and ethnic differences in the prevalence, management, and outcomes in patients with atrial fibrillation: A systematic review
Atrial fibrillation (AF) is the most common cardiac arrhythmia in the United States and is associated with increased morbidity, mortality, and health care expenditures. In this review, our aim was to assess the racial and ethnic differences in the epidemiology, management, and outcomes of patients with AF. A search of relevant studies from January 1, 2007, to December 30, 2017, was conducted in PubMed, EMBASE, and Web of Science and supplemented by manual searches of the bibliographies of retrieved articles.

How to Perform Left Atrial Appendage Electrical Isolation Using Radiofrequency Ablation
Although pulmonary vein isolation (PVI) has been considered an effective treatment for paroxysmal AF, non paroxysmal AF is a complex arrhythmia, for which no ablation strategy has been demonstrated to be effective and widely accepted. As such, a success rate of approximately 55% in these AF patients (Star AF II Trial) is not acceptable in our opinion and efforts should be made to seek for alternative strategies. A significant role of the left atrial appendage (LAA) in the genesis of AF has been described, with several studies reporting a substantial incremental benefit from LAA electrical isolation (LAAEI), in addition to ...

Roads Less Traveled: My journey through electrophysiology and beyond
How things that happen early in life can sometimes turn out to be prophetic. I still can see my hardly recognizable picture in the Junior High School Yearbook. The caption underneath read, “Great oaks come from little nuts.” As I recall, my parents were not impressed but I thought the description was quite accurate. I was barely able to achieve my Bachelor of Science Degree from the City College of New York as a biology major and education minor before being drafted into the Army in 1954 . Little did I know then that my favorite subjects, botany and invertebrate zoology would come to play an important role in m...

Progression of intrahisian atrioventricular block: Will this presage a renaissance of His-bundle studies?
In this issue of HeartRhythm is a very interesting article by Ragupathi et  al,1 who describe the natural history of patients with putative intrahisian atrioventricular (AV) block. The authors have nicely shown that although these patients often present with traumatic and very worrisome syncopal episodes, they seem to have a very low incidence of progression to complete A V block. There are 2 major clinical extrapolations of these observations. First, the low incidence of right ventricular pacing would seem to obviate the risk for development of cardiac failure as a result of asynchronous right ventricular pacing; hen...

Atrial fibrillation mapping strategies: The hunt is on
Patients with drug-refractory persistent atrial fibrillation (AF) account for a significant and increasing portion of those undergoing left atrial ablation for rhythm control, yet outcomes remain less favorable than for patients with paroxysmal AF.1 New techniques are needed to target nonpulmonary vein (non-PV) AF drivers or other substrate factors favoring AF recurrence in these patients. Furthermore, many patients enter the electrophysiology laboratory in refractory AF, underscoring the potential value of mapping during AF. (Source: Heart Rhythm)

Medical devices, including cardiac implantable electronic devices (CIEDs), have become increasingly interconnected, leading to an increased risk of exploitation of cybersecurity vulnerabilities that can affect device functionality. Device interconnectivity and interoperability can provide great benefits to patients, as evidenced by the growing body of literature demonstrating the positive impact of remote monitoring of CIEDs.1 Unfortunately, these benefits are accompanied by the potential for cybersecurity risks – and these are not just theoretical risks.
