Patterns and Risk Factors for Rehospitalizations Within the First 90 Days Following Discharge After Heart Transplantation.

Background: Heart transplantation (HT) recipients are at risk for urgent rehospitalizations following discharge. However, data on prevalence, risk factors and clinical outcomes associated with post-HT rehospitalization are limited.

Methods: This study aims to describe patterns of urgent rehospitalizations in HT recipients at a cardiology reference center in Brazil.

Necropsy findings in heart transplant recipients with or without primary graft dysfunction.

Background: Primary graft dysfunction (PGD) is the leading cause of death in the first year after heart transplant (HT), but pathophysiology and histology are not completely understood. This study describes and compares morphological findings of hearts of patients with and without PGD.

Methods: We included adult patients submitted to HT in a single center who died within the first 14 days after HT and were submitted to necropsy.

Survival of Heart Transplant Patients with Chagas' Disease Under Different Antiproliferative Immunosuppressive Regimens.

Chagas' disease (CD) is an important cause of heart transplantation (HT). The main obstacle is Chagas' disease reactivation (CDR), usually associated to high doses of immunosuppressants. Previous studies have suggested an association of mycophenolate mofetil with increased CDR.

Characteristics and Outcomes of Heart Transplant Recipients With Coronavirus-19 Disease in a High-volume Transplant Center.

Background: Heart transplant (HT) recipients may be at higher risk of acquiring SARS-CoV-2 infection and developing critical illness. The aim of this study is to describe characteristics and outcomes of HT recipients infected by SARS-COV-2, from a high-volume transplant center.

Methods: We have described data of all adult HT recipients with confirmed coronavirus disease 2019 by RT-PCR in nasopharyngeal samples from April 5, 2020, to January 5, 2021.

Epipericardial fat necrosis as cause of chest pain in patient after heart transplantation.

Epipericardial fat necrosis is an uncommon clinical condition of unknown etiology. It typically presents as acute pleuritic chest pain and should be differentiated from acute pulmonary embolism and acute coronary syndrome. This condition is diagnosed by characteristic chest computed tomography findings of an ovoid mediastinal fatty lesion with intrinsic and surrounding soft-tissue stranding.

Bone Metabolism Impairment in Heart Transplant: Results From a Prospective Cohort Study.

Background: Data on the prevention of fractures after heart transplant (HTx) are controversial in the literature. Understanding the effects of HTx on bone may guide appropriate treatments in this high-risk population.

Methods: Seventy adult HTx patients were followed for 12 months.
