Heart Failure After Heart Transplantation Due to Chronic Rejection — AVALON  

Cardiac Allograft Vasculopathy Clinical Trial

Official title: Allograft Vasculopathy and Unexplained Graft Dysfunction During Long-term Follow-up After Heart Transplantation

Status Recruiting

Clinical Trial Summary

This study will investigate the prevalence of allograft vasculopathy and unexplained graft dysfunction during long-term follow-up after heart transplantation. Risk factors as well diagnostic approaches will be investigated.

Clinical Trial Description

During long-term follow-up heart transplant recipients are at risk of developing different complications that are likely to affect quality of life and survival. The most common cause of death during the later stages after heart transplantation is cardiac allograft vasculopathy, followed by unexplained graft dysfunction. In this study, advanced imaging techniques will be used to describe the frequency of these two complications, examine possible risk factors and study consequences on functional capacity and quality of life. Further, the investigators will investigate whether it is feasible to screen for these conditions with non-invasive imaging methods. By studying patients that have performed cardiac transplantation between 10 and 20 years ago, the investigators expect to have a significant proportion of patients with these pathological conditions. Methods that will be used include cardiac magnetic resonance imaging, coronary flow velocity reserve assessment, right heart catheterization and coronary imaging with angiography and optical coherence tomography. ;
