Heart failure and right ventricular pacing - how to avoid the need for cardiac resynchronization therapy.

Expert Rev Med Devices 2018 Nov 26. Epub 2018 Nov 26.

a Leeds Institute of Cardiovascular and Metabolic Medicine, University of Leeds , Leeds , UK.

Introduction: Heart failure is a common finding in patients with pacemakers implanted for bradycardia, with cross-sectional and longitudinal studies contributing to the growing consensus that right ventricular pacing can cause adverse cardiac remodeling and left ventricular systolic dysfunction increasing the risk of hospitalization and death. An unselected approach using cardiac resynchronization therapy from the time of first implant in patients with heart block has produced equivocal results. Contemporary research has therefore begun to focus on the stratification of patients' risk of pacemaker-associated impairment to permit focused, personalized management. Read More

a Department of Interventional Neuroradiology , University Hospital Erasme , Brussels , Belgium.

Introduction: Stent-assisted coiling (SAC) has widened indications of endovascular treatment of intracranial aneurysms (wide-neck, fusiform aneurysms); moreover, it is associated with more stable anatomical results. Besides the development of other techniques such as flow diverter stents, bifurcation stents, or intrasaccular flow disruptors, SAC remains one of the most used endovascular techniques because it provides good clinical and anatomical results for most aneurysms. Several devices based on the same principle are available and have undergone many adaptations and developments over 20 years of intracranial stenting. Read More
