Roof-dependent atrial-flutter after a 28  mm second-generation cryoballoon ablation

A 73-year-old woman underwent a 28  mm 2nd generation cryoballoon ablation, and a roof-dependent atrial-flutter (AFL) was induced just after the pulmonary vein isolation and left atrial (LA) voltage mapping. Ablation of the PV antrum was performed with two applications per vein, one for 180 s followed by another for 150 s. The voltage map during sinus rhythm revealed an overlap of the cryoablation lesion on the LA posterior wall, and the overlapping lesion created slow conduction during the AFL. The AFL terminated after a roof linear ablation, and no further atrial arrhythmias were documented during 1-year of follow-up. T he occurrence of AFL after cryoablation is rare during the follow-up period, however, investigating the mechanism of the AFL after the cryoablation may contribute to an improved clinical outcome.

The human and dog have sinus arrhythmia; however, the beat-to-beat interval changes were hypothesized to be different. Geometric analyses (R-R interval tachograms, dynamic Poincaré plots) to examine rate changes on a beat-to-beat basis were analyzed along with time and frequency domain heart rate variability from 40 human and 130 canine 24-hour electrocardiographic recordings. Humans had bell-shaped beat-interval distributions, narrow interval bands across time with continuous interval change and linear changes in rate. In contrast, dogs had skewed nonsingular beat distributions, wide interval bands {despite faster ...

Background: Ascent to altitude increases the prevalence of arrhythmogenesis in low-altitude dwelling populations (Lowlanders). High altitude populations (i.e., Nepalese Sherpa) may have arrhythmias resistant adaptations that prevent arrhythmogenesis at altitude, though this has not been documented in other High altitude groups, including those diagnosed with chronic mountain sickness (CMS). We investigated whether healthy (CMS-) and CMS afflicted (CMS +) Andeans exhibit cardiac arrhythmias under acute apneic stress at altitude.Methods and Results: Electrocardiograms (lead II) were collected in CMS- (N = 9), CMS + (N = 8), ...

The device touted as the world's smallest pacemaker is now FDA approved for patients with AV block, a condition in which the electrical signals between the chambers of the heart are impaired. FDA approved the original Micra Transcatheter Pacing System in 2016 for patients with atrial fibrillation or other dangerous arrhythmias such as bradycardia-tachycardia syndrome. The Micra AV is identical in size and shape to the original device, but has several additional internal sensing algorithms which detect cardiac movement, allowing the device to adjust pacing in the ventricle to coordinate with the atrium, providin...

By ANISH KOKA, MD Mr. Smith has a problem.  He can’t see.  Even this cardiologist knows why.  The not so subtle evidence lies in the cloudy lens in front of his pupils.  He is afflicted with cataracts that obstruct his vision to the point he can’t really do his job refurbishing antique furniture safely.  His other problem is that he hates doctors. He hasn’t had reason to see one for more than a decade.  He’s 68, takes no medications, smokes a pack of cigarettes a day, and is a master of one word answers. He’s in my office because he needs a medical eval...

Conclusion: Regional electrophysiology and paths in the model match human action potentials, dynamic behavior, and cardiac activation sequences. Connected in closed loop with a pacing device in DDD mode, the model generates complex arrhythmia such as atrioventricular nodal reentry tachycardia. Such device-induced outcomes have been observed clinically and we can establish the key physiological features of the heart model that influence the device operation. Significance: These findings demonstrate how an abstract heart model can be used for device validation and to design personalized treatment.

Atrial fibrillation and hypertension represent 2 of the most important national public health priorities. Atrial fibrillation is the most common sustained cardiac arrhythmia among adults, affecting up to 2% of the US population. The prevalence of atrial fibrillation is expected to increase 3-fold in the next 3 decades. Robust data have identified hypertension as an independent modifiable risk factor for atrial fibrillation and as the most common cardiovascular condition associated with it. Hypertension is present in up to 80% of individuals with atrial fibrillation. Fulfilling a fundamental principle of evidence-based medi...

Atrial Fibrillation (AF) is a common arrhythmia with serious clinical sequelae, but despite its significance little is known about the genetic origins. Recently, the untranscribed 98% of the human genome has been increasingly implicated in important processes like cardiac organogenesis, physiology, and pathophysiology. Specifically, long non-coding RNAs (lncRNA) have been shown to interact with the transcriptome in various ways that alter gene expression. Previously, multiple lncRNAs have been identified in disease processes such as heart failure, coronary artery disease, diabetes, and more.

AbstractThe2015 HRS/EHRA/APHRS/SOLAECE Expert Consensus Statement on Optimal Implantable Cardioverter-Defibrillator Programming and Testing provided guidance on bradycardia programming, tachycardia detection, tachycardia therapy, and defibrillation testing for implantable cardioverter-defibrillator (ICD) patient treatment. The 32 recommendations represented the consensus opinion of the writing group, graded by Class of Recommendation and Level of Evidence. In addition, Appendix B provided manufacturer-specific translations of these recommendations into clinical practice consistent with the recommendations within the parent...

BOSTON (CBS) — Marijuana use is growing in popularity and local doctors are sounding the alarm about the potential harms the drug could have on the heart. They say marijuana carries many of the same cardiovascular risks as smoking tobacco. Researchers at Brigham and Women’s Hospital say while more patients are curbing their use of cigarettes, there has been an acceleration in marijuana use that marijuana users are now exceeding cigarette smokers. And the effects of the drug on cardiovascular health are not fully understood. Some studies have linked marijuana use with stroke, arrhythmias, and other heart conditi...
