Abstract:

As one of the main factors limiting the survival time of patients after heart transplantation, cardiac allograft vasculopathy (CAV) and its exact pathogenesis remains to be explored, which involves vascular endothelial damage and repair response caused by a variety of immune responses and the interaction of non-immune factors. Coronary angiography is the current gold standard for the diagnosis of CAV. Furthermore, transjugular endomyocardial biopsy and intravascular ultrasound are also used to assess CAV. The surgical treatment for CAV is fairly limited. Heart retransplantation is not recommended in clinical practice because of the shortage of donor organs and high risk of complications. Percutaneous coronary intervention and coronary artery bypass grafting can only be used as restricted palliative treatment. Therefore, drug intervention is the current focus for the treatment of CAV. The pathogenesis and drug treatment of CAV will still be the key research direction of heart transplantation for some time to come.
