Objective: Advanced age has traditionally been considered a contraindication for heart transplantation because of the reported adverse effect of increased age on long-term survival. However, as the field of transplantation continues to evolve, the criteria regarding the recipient's upper age limit have been expanded and older patients are being considered as potential candidates. We analyzed the outcome of heart transplantation in patients 70 years of age and older and compared these results with those in younger patients (<70 years) over a 4-year period.
Method: We retrospectively analyzed the results of 15 patients 70 years of age and older who underwent heart transplantation between November 1994 and May 1999 and compared them with results in 98 younger patients undergoing transplantation during the same period
Results: The older age group had a higher preoperative left ventricular ejection fraction (P =.02), higher incidence of female donors (P =.02), and longer cardiac allograft ischemic time (P =.01). No differences were found regarding incidence of diabetes mellitus, donor age, donor/recipient weight ratio, and mismatch (<0.80). The 30-day or to-discharge operative mortality was similar in both groups (0% in the older vs 5.1% in younger patients). Actuarial survival at 1 year and 4 years was not statistically different between the older and younger patients (93.3% +/- 6.4% vs 88.3% +/- 3.3% and 73.5% +/- 13.6% vs 69.1% +/- 5.8%, respectively). The length of intensive care unit stay and total post-transplantation hospital stay, incidence of rejection, and incidence of cytomegalovirus infection were similar between the groups.
Conclusions: Heart transplantation in selected patients 70 years of age and older can be performed as successfully as in younger patients (<70 years of age) with similar morbidity, mortality, and intermediate-term survival. Advanced age as defined (> or =70 years) should not be an exclusion criterion for heart transplantation. The risks and benefits of transplant surgery should be applied individually in a selective fashion.

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.

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.

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.
