- Remote monitoring (RM) of cardiac implantable devices is rapidly becoming the standard of care for implantable cardiac device follow-up.
- Three incisions in the chest are necessary for implantation of the entirely subcutaneous implantable cardioverter-defibrillator (S-ICD). The superior parasternal incision is a possible risk for infection and a potential source of discomfort. A less invasive alternative technique of implanting the S-ICD electrode—the two-incision technique—avoids the superior parasternal incision.
- Advances in cardiac care of the young have given rise to a growing and aging population of patients with congenital heart disease. Despite remarkable improvements in overall survival, sudden cardiac death remains the most common cause of late mortality. As a result, implantable cardioverter-defibrillators (ICDs) are increasingly used in this heterogeneous patient population. Tetralogy of Fallot and transposition of the great arteries are the most prevalent subtypes of congenital heart disease in ICD recipients.
- The progressive understanding of the diseases associated with significant risk for sudden cardiac death has fostered the development of early diagnosis and risk stratification. Thus, instead of starting from either a sudden death victim or a survivor of a cardiac arrest, it has become relatively common for cardiologists to identify individuals at high risk for sudden death, often after an arrhythmic nonlethal cardiac event such as syncope. Besides ischemic heart disease, it has also been recognized that children and young adults can be affected by arrhythmogenic disorders of genetic origin with a high propensity for lethal arrhythmias.
- Implantable cardioverter-defibrillator (ICD) usage has increased dramatically over the past decade. In part this is due to improved patient survival after myocardial infarction, but principally this is due to the increased number of implants for primary prevention. While the salutary effects of ICD therapy in this population of patients are generally accepted, complications from ICD implantation have become a common and pressing issue. First among these complications, both in terms of frequency and impact on quality of life, is inappropriate ICD therapy.
