Primary prevention implantable cardioverter-defibrillator and cardiac resynchronization therapy-defibrillator in elderly patients: results of a Spanish multicentre study.

Aims: Currently, there continues to be a lack of evidence regarding outcomes associated with device-based therapy for ventricular arrhythmias in elderly patients, even more in primary-prevention indications. We aimed to describe the follow-up in terms of efficacy and safety of implantable cardioverter-defibrillator (ICD) therapy in a large cohort of elderly patients.

Methods And Results: Retrospective multicentre study performed in 15 Spanish hospitals.

Primary Prevention of Sudden Death in Patients With Valvular Cardiomyopathy.

Introduction And Objectives: Few data exist on the outcomes of valvular cardiomyopathy patients referred for defibrillator implantation for primary prevention. The aim of the present study was to describe the outcomes of this cardiomyopathy subgroup.

Methods: This multicenter retrospective study included consecutive patients referred for defibrillator implantation to 15 Spanish centers in 2010 and 2011, and to 3 centers after 1 January 2008.

[Electrical storm in patients with prophylactic defibrillator implantation].

Introduction: Little is known about the prevalence of electrical storm, baseline characteristics and mortality implications of patients with implantable cardioverter defibrillator in primary prevention versus those patients without electrical storm. We sought to assess the prevalence, baseline risk profile and survival significance of electrical storm in patients with implantable defibrillator for primary prevention.

Methods: Retrospective multicenter study performed in 15 Spanish hospitals.
