May 21, 2018 — A recent study published in Heart and Vessels has found that the use of the Baylis Medical NRG radiofrequency (RF) Transseptal Needle for transseptal punctures was linked to a 40 percent lower incidence of silent acute cerebral embolism in atrial fibrillation (AF) ablation procedure patients.[1] 

Data on the effectiveness of cardiac resynchronization therapy (CRT) in patients with non-left bundle branch block (non-LBBB) is limited and when available has been shown to be suboptimal compared to LBBB patients. A new study presented at the 2018 Heart Rhythm Society (HRS) Scientific Sessions, May 9-12 in Boston, compared the effects of targeting the region of increased electrical delay (QLV approach) for left ventricular (LV) lead location to a standard of care (SOC) anatomical implant approach in non-LBBB patients. The comparison was assessed on the Clinical Composite Score (CCS) after 12 months of follow-up.

In a new study, cardiac contractility modulation (CCM) therapy was confirmed to significantly improve exercise tolerance (ET) and quality of life (QoL) for patients with persistent symptomatic heart failure and an ejection fraction between 25 and 45 percent.  Results of the prospective FIX-HF-5C Study were presented at the 2018 Heart Rhythm Society (HRS) Scientific Sessions, May 9-12 in Boston.

May 18, 2018 — Left atrial appendage closure (LAAC) with the transcatheter Watchman device prevents thromboembolism from the LAA, but a new study shows that thrombus forms on the face of the device in about 3.7 percent of patients and it can embolize. The study was presented at Heart Rhythm 2018, the Heart Rhythm Society’s 39th Annual Scientific Sessions.

May 18, 2018 — Catheter ablation for atrial fibrillation (AF) in patients with heart failure in the CASTLE-AF Trial was associated with significant improvement in AF burden compared to medical therapy.[1] The study was presented at Heart Rhythm 2018, the Heart Rhythm Society’s 39th Annual Scientific Sessions.

May 18, 2018 — Nearly half of patients prescribed warfarin and just under one third of those using newer direct oral anticoagulants do not maintain adherence above 80 percent. This leads to increased risks for thromboembolic events. This was according to a new study presented at Heart Rhythm 2018, the Heart Rhythm Society’s 39th Annual Scientific Sessions.

May 18, 2018 — A significant number of patients with symptomatic premature ventricular contractions (PVCs) have underlying myocarditis identified by FDG-PET, and treatment with immunosuppressive therapy may significantly impact outcomes. This was a key finding in a review of the Myocarditis and Ventricular Arrhythmia (MAVERIC) Registry presented at Heart Rhythm 2018, the Heart Rhythm Society’s 39th Annual Scientific Sessions. 

 

May 18, 2018 — Three year results of a study found injection of botulinum toxin into epicardial fat pads in patients undergoing coronary artery bypass grafting (CABG) has resulted in substantial atrial fibrillation (AF) suppression. The results were presented at Heart Rhythm 2018, the Heart Rhythm Society’s 39th Annual Scientific Sessions.
