Magnetic Resonance Imaging Clinical Trial
Official title:
Morphological and Functional Changes After Heart Transplantation - Role of Noninvasive Imaging in the Early Detection of Cardiac Allograft Rejection and Vasculopathy
The cardiac allograft rejection (CAR) and cardiac allograft vasculopathy (CAV) significantly affect the prognosis of patients after heart transplantation. The aim of the present study is to investigate and differentiate the adaptive and pathological cardiovascular changes after heart transplantation using different modalities. The investigator's main purpose is to define the role of the cardiovascular imaging methods and biomarkers in the early diagnosis of CAR and CAV.
1. 12-lead ECG - Resting standard 12-lead digital ECG will be recorded. Extended analysis
will be performed according to the latest recommendations.
2. Holter ECG - 24 hour Holter ECG will be recorded. Extended Holter ECG analysis will be
performed.
3. Life quality questionnaire, patient history - Detailed questionnaire about personal and
family history, general symptoms and life quality.
4. Laboratory biochemical examination - Besides the regular routine laboratory parameters,
several specific parameters are planned to be measured, such as cardiac biomarkers.
5. Endomyocardial biopsy
6. Detailed transthoracic echocardiography including strain analysis and 3D measurement
7. Detailed cardiac magnetic resonance (CMR) examination
8. Coronary imaging - invasive coronarography and intravascular ultrasound (IVUS) and/or
optical coherence tomography (OCT)
9. Invasive pressure measurement - Measurement of coronary flow reserve (CFR) and
microcirculation resistance index (IMR)
