  • Cardiac amyloidosis is one of the most common infiltrative cardiomyopathies that is characterized by the extracellular deposition of misfolded fibrillar protein. Several studies have previously found that patients with amyloid in the past have performed poorly after heart transplantation. Recent advancements in treatments have been made that have significantly improved outcomes in these patients. The study aimed to evaluate the outcomes of heart transplantation in cardiac amyloidosis. We systematically searched EMBASE, PubMed/MEDLINE, and Cochrane Library databases on 30 December 2021 following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. We identified 22 studies that examined 42,951 patients with cardiac amyloidosis of which only 1,329 patients underwent isolated heart transplantation. Seven studies reported individual patient data. The results of 123 patients have been pooled for analysis. There were 70 male patients, 45 female patients, and eight patients who did not report their gender. Among the types of amyloids, 63 (51%) patients were found to have light chain amyloidosis (AL) and 33 (27%) patients had transthyretin amyloidosis (ATTR). Only 41 patients (33.3%) reported a monoclonal component. There were 30 patients with AL that underwent autologous hematopoietic stem cell transplant (ASCT). The mean survival of 24 out of 30 patients was 4.33 years. In addition, the reported data include 13 patients requiring intra-aortic balloon pump (IABP), six with cardiac resynchronization therapy (CRT), and four with implantable cardioverter defibrillator (ICD). With the current advancements in treatments in combination with a multidisciplinary approach and careful patient selection, patients undergoing heart transplantation for amyloidosis may have encouraging results in the current era. Further studies will be needed to evaluate the outcomes of heart transplantation in amyloidosis patients now that several advances have been made in the field.
