One of the main causes of death beyond the first year after heart transplantation is cardiac allograft vasculopathy (CAV). This review summarises the current understanding of its complex pathophysiology, detection and treatment, including the available data on non-invasive imaging modalities used for screening and diagnosis. A better understanding of this entity is crucial to improving the long-term outcomes of the growing population of patients with a heart transplant.

Is it time to adopt angiotensin receptor-neprilysin inhibitors (ARNI) therapy as standard of care for the management of hypertension?

Heart transplantation is the gold standard in patients with end stage heart failure, offering vastly improved survival, mortality and quality of life. However, hypertension occurring after cardiac transplantation is a serious issue, with the incidence ranging from 50 to 80% of patients. The pathophysiology of the hypertension encompasses a more varied and unique set of causes than those identified in non-organ transplant patients, particularly related to the use of calcineurin inhibitors (CNIs) especially cyclosporine. An in-depth understanding of hypertension after heart transplantation remains a critical issue that necessitates further clarification, due to its deleterious long-term consequence such as impaired graft survival, cardiac allograft vasculopathy (CAV), and overall survival. This article provides a comprehensive review of the prevalence, risk factors, etiology, complications, and management of hypertension after heart transplantation.
