An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart.
A meta-analysis of 11 comparable studies with approximately 20,000 non-overlapping patients in different indications was published by Nguyen et al. [49] They found an overall mortality rate of 1.4%, a VT/VF rate of 2.6% and a VT/VF-related mortality rate of only 0.2% across all patients. 1.7% of the patients (9.1 patients/100 patient years) had ...
Defibrillators can be external, transvenous, or implanted (implantable cardioverter-defibrillator), depending on the type of device used or needed. [5] Some external units, known as automated external defibrillators (AEDs), automate the diagnosis of treatable rhythms, meaning that lay responders or bystanders are able to use them successfully ...
It remains unknown if surgery is superior to optimal medical therapy. The STICH trial (Surgical Treatment for IschemiC Heart Failure) will examine the role of medical treatment, coronary artery bypass surgery and left ventricle remodeling surgery in heart failure patients. Results are expected to be published in 2009 [needs update] and 2011. [56]
The trial provided clinical evidence of improved survival rates and quality of life for a broad range of patients. [ 53 ] [ 54 ] Eighteen-month follow up data on 281 patients who had either reached the study end-point or completed 18 months of post-operative follow-up showed improved survival, less frequent adverse events and greater ...
An implantable cardiac defibrillator may be recommended in those with certain types of irregular heartbeat. [7] Surgery, in the form of a septal myectomy or heart transplant, may be done in those who do not improve with other measures. [7] With treatment, the risk of death from the disease is less than one percent per year. [9]
