Assessment of patients' and caregivers' informational and decisional needs for left ventricular assist device placement: implications for informed consent and shared decision-making.
The authors investigated the decision-making process and informational and decisional needs of patients and their caregivers regarding left ventricular assist device (LVAD) placement. They found that participants easily and clearly identified their values: life extension; family; and mobility. Participants reported the need to meet other patients and caregivers before device placement and to have an involved caregiver to synthesize information. They further found that some participants demonstrated a lack of clarity regarding transplant probability.

Real world effectiveness of primary implantable cardioverter defibrillators implanted during hospital admissions for exacerbation of heart failure or other acute co-morbidities: cohort study of older patients with heart failure.
The researchers examined the effectiveness of primary implantable cardioverter defibrillators (ICDs) in elderly patients receiving the device during a hospital admission for exacerbation of heart failure or other acute co-morbidities. They concluded that the benefits of primary ICD therapy seen in pivotal trials were not apparent in patients aged 66 or over who received ICDs during a hospital admission for exacerbation of heart failure or other acute co-morbidities.

Implantable cardioverter-defibrillator use among Medicare patients with low ejection fraction after acute myocardial infarction.
This study examined Implantable Cardioverter-Defibrillator (ICD) implantation rates and associated mortality among older MI patients with low ejection fraction (EF). It found that fewer than 1 in 10 eligible patients with low EF received an ICD within 1 year after MI, although ICD implantation was associated with lower risk-adjusted mortality at 2 years.

Age and sex differences in long-term outcomes following implantable cardioverter-defibrillator placement in contemporary clinical practice: findings from the Cardiovascular Research Network.
The objectives of this study were to characterize the risks of adverse outcomes in women and older patients. following implantable cardioverter-defibrillator placement with a focus on death, hospitalization, and complications. It concluded that the burden of adverse outcomes is substantial and varies according to patient age and sex. These differences in outcome generally do not vary according to baseline heart failure characteristics.

Does age influence cardiac resynchronization therapy use and outcome?
This study sought to describe the use of cardiac resynchronization therapy with defibrillator (CRT-D) and its association with survival for older patients. It found that receipt of CRT-D was associated with better survival at 1 year (82.1 percent vs. 77.1 percent, respectively) and 4 years (54.0 percent vs. 46.2 percent , respectively) than in those receiving only an implantable cardiac defibrillator.

Adherence to endovascular aortic aneurysm repair device instructions for use guidelines has no impact on outcomes.
The authors reported on their long-term endovascular aortic aneurysm repair (EVAR) experience in a large multicenter registry with regard to adherence to instructions for use (IFU) guidelines. They found that overall mortality and aneurysm-related mortality were unaffected by IFU adherence, and that rates of endoleak and reintervention after initial EVAR were similar, suggesting that lack of IFU-based anatomic suitability was not a driver of outcomes.
