Expert Review of Medical Devices | Year: 2010
The number of children with congenital heart disease surviving into adulthood has increased dramatically. Refinement in surgical techniques and effective subsequent care has mainly been responsible for this change. However, many of these survivors have significant lifestyle altering symptoms associated with rhythm disorders. These may result from the primary congenital anomaly or from surgical correction. Tachyarrhythmias often result from re-entrant circuits around surgical scars in the setting of a markedly enlarged cardiac chamber. Symptomatic bradyarrhythmias may result from surgical interruption of the conduction system or from the use of antiarrhythmic medication. The management of these lifestyle altering rhythm disorders frequently involves cardiac devices, including pacemakers, antitachycardia devices, defibrillators and resynchronization devices. We review the underlying causes for common rhythm disorders and discuss the specific challenges with cardiac device use in the adult congenital heart disease population. In addition, we address pacing for improvement of ventricular function and innovations likely to impact the field. © 2010 Expert Reviews Ltd.

Congestive Heart Failure | Year: 2011
Summarizing current guidelines and advanced heart failure (AHF) clinical trials/registries, this review focuses on the current definition of AHF and emphasizes the secular trends in this definition over the last two decades. Further, clinical, imaging, hemodynamic, functional capacity and biomarker parameters that may aid clinicians to better recognize patients with AHF are reviewed. Finally, we review the limited data concerning the epidemiology of AHF which to date has been poorly characterized. © 2011 Wiley Periodicals, Inc.
