Self-organized pacemakers in birhythmic media

, 2002
A birhythmic dynamical system is characterized by two coexisting stable limit cycles. In this article, a general reaction-diffusion system close to a supercritical pitchfork-Hopf bifurcation is investigated, where a soft onset of birhythmicity is ...

Malposition of a Port Catheter in the Azygos Vein: Endovascular Repositioning Using a Long Loop Snare Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Port catheters provide a reliable, long‐term venous access option in children for repeated administration of medications or parenteral nutrition. A cardiac catheterization procedure was performed in a 7‐year‐old girl in whom lateral chest radiography revealed posterior deviation suggestive of azygos vein malposition.

Magnetic Resonance Imaging in patients with ICDs and Pacemakers

, 2005
Magnetic resonance (MR) imaging has unparalleled soft-tissue imaging capabilities. The presence of devices such as pacemakers and implantable cardioverter/defibrillators (ICDs), however, is historically considered a contraindication to MR imaging.

Changing experience with dual chamber (DDD) pacemakers

, 1984
Dual chamber (DDD) or “universal” pacemakers have had a significant impact on the advancement of artificial pacemakers by providing a more physiologic approach to cardiac pacing. However, with the early generation of DDD pacemakers (pacemakers that sense

Pre‐Existing and New‐Onset Atrial Fibrillation in Patients Undergoing Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Atrial fibrillation (AF) is a frequent comorbidity in patients with severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). In addition, new‐onset AF can occur after TAVI. However, data on how AF affects outcomes in patients undergoing TAVI remain conflicting.

Single Centre Experience With the Balloon‐Expandable Myval Transcatheter Aortic Valve System in Patients With Bicuspid Anatomy: 1 Year Follow‐Up

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) anatomy remains challenging due to anatomical complexity and limited trial data. New‐generation balloon‐expandable valves, such as Myval, require further evaluation in this subgroup.

Managing Temporary Epicardial Pacemakers with Confidence

, 2022
Session Summary Patients often require a temporary epicardial pacemaker after cardiac surgery to sustain a stable cardiac rhythm. Nurses must be able to manage pacemakers and avoid malfunctioning which can lead to adverse outcomes.

Clinical and Echocardiographic Outcomes After Implantation of the ALLEGRA Transcatheter Valve Using the Fully Repositionable IMPERIA Delivery System: One‐Year Results of the EMPIRE I Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The EMPIRE I study assessed the early (30 days) safety and efficacy of a new fully repositionable delivery system (IMPERIA) for the commercially available ALLEGRA transcatheter aortic valve in patients with either severe native aortic stenosis or a degenerated surgical bioprosthesis.
