Permanent His bundle pacing and atrioventricular node ablation in a case with drug-refractory atrial fibrillation.

Permanent His bundle pacing and atrioventricular node ablation in a case with drug-refractory atrial fibrillation. Turk Kardiyol Dern Ars. 2019 Dec;47(8):691-694 Authors: Saygi S, Erturk E, Topaloğlu C, Abusharekh M Abstract Permanent His bundle pacing (HBP) activates the ventricles through the normal conduction system and has become a useful technique for patients with a high ventricular pacing rate. Presently described is a case of drug-refractory atrial fibrillation (AF) with a high ventricular rate that was treated with atrioventricular (AV) node ablation and permanent HBP. A 62-year-old woman with persistent AF and a drug-refractory high ventricular response was referred for exercise intolerance and palpitation. She had a history of failed catheter ablation attempts and amiodarone toxicity. Permanent HBP and AV node ablation was planned to achieve rate control with a stepwise approach. Initially, implantation of a permanent pacemaker was performed. The His lead and right ventricular back-up leads were implanted successfully, in the manner described previously. The His lead was connected to the atrial channel of the pacemaker battery and programmed to AAI pacing mode. The AV node was ablated successfully 3 weeks later without any threshold changes in the His lead. No His lead threshold changes were observed during or after AV node ablation and the patient was subsequently asymptomatic with twice daily apixaban 5 mg. Permanent HBP after AV node ablat...

Abbott Laboratories continues to extend its list of milestones in the cardiovascular space. The Abbott Park, IL-based company has now won Breakthrough Device Designation from FDA for the in-development Fully Implantable Left Ventricular Assist System (FILVAS). FILVAS builds on the HeartMate 3 Left Ventricular Assist Device (LVAD). The technology was inherited by St. Jude Medical when it was acquired by Abbott. St. Jude inherited Heartmate 3 after it acquiredThoratec for $3.4 billion. Kevin Bourque, Divisional Vice President of Research &Development for Abbott’s Mechanical Circulatory Support portfol...

Michel Mirowski and his colleagues gave the field of implantable cardioverter-defibrillators (ICDs) a pretty good start, but what's more impressive is how far the technology has advanced since that first human ICD implant in February 1980. In the past 40 years we've seen ICDs become dramatically smaller, longer lasting, more capable, more personalized, subcutaneous (non-transvenous), and even MRI-firendly. And that's not to mention the advanced data connectivity and monitoring capabilities that the latest technologies offer. So without further ado, let's take a look at the current ICD landscape and the companie...

Authors: Abe S, Yoshihisa A, Ichijo Y, Sato Y, Kanno Y, Takiguchi M, Yokokawa T, Misaka T, Sato T, Oikawa M, Kobayashi A, Yamaki T, Kunii H, Takeishi Y Abstract It has been recently recognized that recovery of left ventricular ejection fraction (EF), termed "recovered EF", occurs in a proportion of heart failure patients with reduced EF (HFrEF), and is associated with better prognosis. However, the clinical characteristics of "recovered EF" have not been fully examined.Consecutive 567 patients hospitalized due to HFrEF (EF

ConclusionThis analysis from the European CRT Survey II overall shows good guideline adherence, high implantation success and a low rate of complications in daily practice. There are some regional differences in baseline characteristics, CRT indication, and procedural aspects. The use of remote monitoring in Germany lags behind other European countries.Graphic abstract

Conclusions. Patients in AF or SR undergoing CRT demonstrated distinct benefits from device implantation and from HIIT as an adjunctive therapeutic strategy. This suggests that both mainstay and adjunctive therapeutics may need to be managed differently in patients in AF and SR. PMID: 31221002 [PubMed - as supplied by publisher]
