However, heart transplant patients lack nerve connections in the transplanted heart and therefore usually do not notice any symptoms. For this reason, routine examinations are performed using traditional coronary angiography at one, three, and six years after transplantation, sometimes with the addition of coronary ultrasound.\n\nA new technique, photon-counting computed tomography, has now been developed and may potentially replace both traditional coronary angiography and intravascular ultrasound. In this study, we aim to investigate how well this method works in diagnosing coronary artery changes compared to the established methods.",[73],"Cardiac Allograft Vasculopathy",[75,76,77,78,79],"Heart transplantation","Cardiac allograft vasculopathy","photon counting computed tomography","Invasive coronary angiography","Intravascular ultrasound","NOT_YET_RECRUITING","2025-06-05",{"date":83,"type":84},"2025-06-13","ACTUAL",{"date":86,"type":68},"2025-09-01",{"date":88,"type":68},"2027-08-31",{"name":5,"class":6},1]
