IMPACT OF EJECTION FRACTION ON SURVIVAL BENEFIT WITH IMPLANTABLE CARDIOVERTER-DEFIBRILLATOR THERAPY

Implantable cardioverter defibrillator outcome: beyond ejection fraction?

Over three decades of clinical experience have brought evidence that implantable cardioverter defibrillators (ICDs) should be considered as ‘gold standard’ therapy in prevention of sudden cardiac death. Implantable cardioverter defibrillators are currently indicated for secondary prevention in patients after cardiac arrest and life-threatening ventricular tachyarrhythmias or for primary prevent...

Long-Term Benefit and Challenges of Implantable Cardioverter Defibrillator Therapy

Maximizing survival benefit with primary prevention implantable cardioverter-defibrillator therapy in a heart failure population.

BACKGROUND Although implantable cardioverter-defibrillator (ICD) therapy reduces mortality in moderately symptomatic heart failure patients with an ejection fraction <or=35%, many such patients do not require ICD shocks over long-term follow-up. METHODS AND RESULTS Using a modification of a previously validated risk prediction model based on routine clinical variables, we examined the relatio...

Implantable cardioverter-defibrillator in a patient with dextrocardia situs inversus

Background: Dextrocardia is a congenital anomaly, which may have coexistent coronary artery disease (CAD), arrhythmias and conventional indications for device therapy. However, the implantation of transvenous leads can be technically challenging and the approach needs to be tailored to the patient's individual anatomy. Case presentation: A 54-year-old male with dextrocardia situs inversus and i...

Implantable Cardioverter-Defibrillator Use Among Medicare Patients With Low Ejection Fraction After Acute Myocardial Infarction.

IMPORTANCE Implantable cardioverter-defibrillators (ICDs) are not recommended within 40 days of myocardial infarction (MI); thus, ICD implantation might not be considered during the post-MI care transition. OBJECTIVE To examine ICD implantation rates and associated mortality among older MI patients with low ejection fraction (EF). DESIGN, SETTING, AND PARTICIPANTS Retrospective observationa...
