Facilitators and Barriers to Values Discussions Following LVAD Implantation: Perspectives from Diverse Patients and Family Caregivers.

Background Delivering care that is responsive to who or what is most important to patients and family caregivers is a key aspect of quality care, yet it remains unclear how clinicians can best support individuals in expressing their personal values. We aimed to describe patient- and family caregiver-identified facilitators and barriers to engaging in values discussions with clinicians following implantation of a left ventricular assist device (LVAD). Methods and results Using a qualitative descriptive approach, patients with an LVAD and their caregivers participated in one-on-one semi structured interviews and self-reported sociodemographics (January 2023-July 2023).

Antithrombotic therapy in patients with atrial high-rate episodes (AHREs): Current evidence and open questions.

With the increasing use of cardiac electronic implantable devices in recent years, the identification of asymptomatic atrial arrhythmias, including atrial high-rate episodes (AHREs) and device-detected subclinical atrial fibrillation (SCAF), has become common in clinical practice. AHREs have potentially important clinical implications because they are considered precursors of atrial fibrillation (AF). Although to a lesser extent than clinical AF, both AHREs and device-detected SCAF are associated with thromboembolic events, however routine use of anticoagulants in these conditions is not recommended.

Objectives: The objective of this study was to use cardiac implantable electronic devices (CIEDs) capable of AF diagnosis to compare AF incidence between Black and White individuals.

Citrate-Coated Iron Oxide Nanoparticles Facilitate Endothelialization of Left Ventricular Assist Device Impeller for Improved Antithrombogenicity.

Although left ventricular assist devices (LVADs) are an alternative to heart transplantation, their artificial surfaces often lead to serious thrombotic complications requiring high-risk device replacement. Coating blood-contacting surfaces with antithrombogenic endothelial cells is considered an effective strategy for preventing thrombus formation. However, this concept has not yet been successfully implemented in LVADs, as severe cell loss is to be expected, especially on the impeller surface with high prothrombogenic supraphysiological shear stress.

Cardiac Implantable Electronic Devices in Cardiac Transplant Patients: A Comprehensive Review.

A fraction of patients (approximately 10%) undergoing heart transplantation require permanent pacemaker (PPM) implantation due to sinus node dysfunction or atrioventricular block, occurring either shortly after surgery or later. The incidence of PPM implantation has declined to less than 5% with the introduction of bicaval anastomosis transplantation surgery. Pacing dependency during follow-up varies among recipients.
