St. Jude wins CE Mark for MR-safe Quadra Assura CRT-D

St. Jude Medical (NYSE:STJ) said today it won CE Mark approval in the European Union for MRI-conditional labelling for its Quadra Assura cardiac resynchronization therapy defibrillator. The Quadra Assura CRT-D is compatible with MRI scanning systems up to 1.5 Tesla, St. Paul, Minn.-based St. Jude said. “The Quadra Assura CRT-D MRI allows patients to continue to be actively paced and continuously monitored with the quadripolar pacing technology while having the capability to get an MRI scan if needed. Being able to offer MRI-compatible technology without compromising care decisions is extremely important; this is yet another valuable tool for us to treat patients living with heart failure,” Dr. Giovanni Forleo of Rome’s University Hospital of Tor Vergata said in prepared remarks. St. Jude said its Quadra Assura CRT-D was the 1st-to market quadripolar multipoint CRT-D, with technologies that allow for multiple pacing locations on the left side of the heart. “Adding MRI availability to our market-leading quadripolar technology advances options for patients and ensures future access to diagnostic imaging they may need in their heart failure treatment. We remain committed to being the leader in quadripolar technology while continuing to focus on improving patients’ quality of life,” St. Jude group prez Dr. Eric Fain said in a press release. Last September, St. Jude said it was taking many of its already-approved devices back to re...

ConclusionsBoth typical LBBB and LBBB ‐like pattern might be associated with constant activation sequence regardless of etiology and scar localization. Activation initiation in RV apex, not LV activation sequence can be surrogate for left axis deviation. CRT caused inter‐ and intraventricular LV resynchronization without significant ly changed RV activation sequence and duration.This article is protected by copyright. All rights reserved

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]

AbstractNoninvasive imaging modalities offer the possibility to dynamically evaluate cardiac motion during the cardiac cycle by means of ECG-gated acquisitions. Such motion characterization along with orientation, segmentation preprocessing, and ultimately, phase analysis, can provide quantitative estimates of ventricular mechanical synchrony. Current evidence on the role of mechanical synchrony evaluation is mainly available for echocardiography and gated single-photon emission computed tomography, but less is known about the utilization of gated positron emission tomography (PET). Although data available are sparse, ther...

Authors: Perge P, Boros AM, Zima E, Gellér L, Merkely B, Széplaki G Abstract OBJECTIVES: Changes in the levels of serum creatinine and N-terminal of prohormone brain natriuretic peptide (NT-proBNP) are useful risk markers after cardiac resynchronization therapy (CRT). The diagnostic value of changes in serum uric acid levels has been established in chronic heart failure, but no data are available on the prognostic value of hyperuricemia in a CRT population. DESIGN: We measured markers of renal function [creatinine, blood urea nitrogen (BUN) and uric acid] and NT-proBNP levels of 129 heart failure ...

CONCLUSION: cQLV is a simple measure that can identify a vulnerable cohort of CRT patients at increased risk for atrial tachyarrhythmias, and hence can predict reverse remodeling and clinical response to CRT treatment. PMID: 30570402 [PubMed - as supplied by publisher]

CONCLUSION: In this long-term follow-up in patients with atrial fibrillation treated with AVJ ablation and pacing, indication, choice of pacing system, and morbidity differed but there were no sex differences regarding survival or primary cause of death found. The main factor influencing survival was age at the time of ablation. Women less often received treatment with ICD and/or CRT when indication was present compared with men.

FDA approved Medtronic's Azure pacemakers, which feature the company's new BlueSync technology to protect patients from having their device hacked. The BlueSync technology is also now available with the Medtronic Percepta portfolio of quadripolar, MR-conditional cardiac resynchronization therapy pacemakers (CRT-Ps), the company said. BlueSync is intended to enable more secure wireless remote monitoring via Medtronic's CareLink Network, by limiting access to the device functionality and also by protecting patient data. Connected medical devices like pacemakers add value to patient care by enabling remote patient monito...
