Heart transplantation is an accepted treatment for select patients with end-stage heart failure. Improvements to immunosuppressive therapies and patient management have increased the half-life of heart transplant patients to over 10 years.
Donor and recipient characteristics (age, sex, height, weight, and body mass index [BMI]), in particular, donor-recipient mismatches of these characteristics, are associated with cardiac MRI–derived measures of edema and/or inflammation, interstitial expansion and/or fibrosis, and systolic and diastolic dysfunction, suggesting the importance ...
Results: Sex-influenced cardiac MRI measures of myocardial tissue and function are as follows: Female HTx recipients demonstrated increased precontrast T1 ( P = .002) and reduced systolic peak long-axis velocities ( P = .015).
27 Αυγ 2018 · The diagnosis of acute rejection in cardiac transplant recipients requires invasive technique with endomyocardial biopsy (EMB) which has risks and limitations. Cardiovascular magnetic resonance imaging (CMR) with T2 and T1 mapping is a promising technique for characterizing myocardial tissue.
20 Φεβ 2024 · Graft dysfunction (GD) after heart transplantation (HTx) can develop without evidence of cell- or antibody-mediated rejection. Cardiac magnetic resonance imaging (CMR) has an evolving role in detecting rejection; however, its role in biopsy-negative GD has not been described.
8 Φεβ 2019 · This article highlights expected imaging findings after transplant surgery and procedure- and treatment-related complications in the early, intermediate, and late posttransplant periods, to help radiologists identify imaging abnormalities, guide therapy, and affect patient outcomes.
11 Ιαν 2022 · A systematic review and meta-analysis found T2 mapping had the highest noninvasive diagnostic accuracy for evaluating acute cardiac transplant rejection. The study findings were published in JACC: Cardiovascular Imaging.
