8 of 122 patients receiving an implantable cardioverter defibrillator (ICD) in our department since 1985 for the treatment of ventricular tachyarrhythmias were considered candidates for cardiac transplantation. In 6 of 8 patients, at least one successful ICD discharge (range 1-378 discharges) was documented in the follow up time until transplantation. These therapies included cardioversions/defibrillations as well as overdrive stimulation in sustained monomorphic ventricular tachycardia. 1 patient died shortly before receiving a compatible organ. The remaining 7 patients survived successful heart transplantation undertaken 7-34 months after implantation of the cardioverter defibrillator. Cardiac transplantation was not complicated in any of these patients by the previous ICD management. Our results show the high efficacy of ICD as "bridge to transplant" therapy unit cardiac transplantation.

Screening for cardiac sarcoidosis: diagnostic approach and long-term follow-up in a tertiary centre.
Neth Heart J
January 2025
Department of Cardiology, Thorax Centre, Cardiovascular Institute, Erasmus Medical Centre, Rotterdam, The Netherlands.
Background: Cardiac sarcoidosis (CS) is associated with poor prognosis, making early diagnosis and treatment important. This study evaluated the results of a diagnostic approach in patients with known sarcoidosis and suspected cardiac involvement in a tertiary centre and their long-term outcomes.
Methods: We included 180 patients with sarcoidosis and a clinical suspicion of CS.
Preservation of Cardiac Xenografts in a Model of Infant Human Cardiac Transplantation.

Introduction: There is no standard protocol for management of organ preservation for orthotopic, life-sustaining cardiac xenotransplantation, particularly for hearts from pediatric sized donors. Standard techniques and solutions successful in human allotransplantation are not viable. We theorized that a solution commonly used in reparative cardiac surgery in human children would suffice by exploiting the advantages inherent to xenotransplantation, namely the ability to reduce organ ischemic times by co-locating the donor and recipient.

Impact of Heart Transplant Allocation Changes on Waitlist Mortality and Clinical Practice in Pediatric and Adult Patients With Congenital Heart Disease and Cardiomyopathy.
Circulation

Division of Cardiology, Children's Hospital of Philadelphia and Department of Pediatrics (L.W., M.J.O., H.A., J.E., K.Y.L., C.W.-W., J.R., J.B.E.), University of Pennsylvania, Philadelphia.
Background: The United Network of Organ Sharing made changes to the priority for allocation of hearts for transplantation (HT) in 2016 for pediatric patients and 2018 for adult patients. Although recent work has evaluated the impact of the revised allocation systems on mechanical circulatory support practices and waitlist outcomes, there are limited data that focus more specifically on the impact of the allocation changes on patients with congenital heart disease (CHD) or cardiomyopathy and how these relationships might differ in pediatric and adult patients.
Methods: The United Network of Organ Sharing database was queried for pediatric (<18 years of age) and adult (18-50 years of age) patients with a CHD or cardiomyopathy diagnosis listed for HT.
