Background: Remote follow-up of implanted implantable cardioverter defibrillators (ICDs) may offer a solution to the problem of overcrowded outpatient clinics, and may also be effective in detecting clinical events early. Data obtained from remote follow up systems, as developed by all major device companies, are stored in a central database system, operated and owned by the device company. A problem now arises that the patient's clinical information is partly stored in the local electronic... Abstract

International journal of cardiology, Volume 168, Issue 3, 18 3 2013, Pages 2487-2493 Heart failure admissions in adults with congenital heart disease; risk factors and prognosis. Zomer AC, Vaartjes I, van der Velde ET, de Jong HM, Konings TC, Wagenaar LJ, Heesen WF, Eerens F, Baur LH, Grobbee DE, Mulder BJ
Background: Heart failure (HF) is a serious complication and often the cause of death in adults with congenital heart disease (CHD). Therefore, our aims were to determine the frequency of HF-admissions, and to assess risk factors of first HF-admission and of mortality after first HF-admission in adults with CHD. Methods: The Dutch CONCOR registry was linked to the Hospital Discharge Registry and National Mortality Registry to obtain data on HF-admissions and mortality. Risk factors for both HF-a... Abstract

With recent advances in medical and surgical management, most patients with congenital heart disease (CHD) survive to reproductive age. Current guidelines recommend counseling about inheritance and transmission of CHD to offspring. We evaluated whether adult CHD patients recalled having received information about the inheritance of their CHD, patients' knowledge about inheritance and their concerns in this regard. A questionnaire was sent to 486 non-syndromic CHD patients aged 20-45 years.... Abstract
