Brief Summary

The aim of the mCAV study is a comprehensive characterization of the genetic, morphological and functional phenotype of isolated microvascular graft vasculopathy (mCAV) after orthotopic heart transplantation (OHT). The utilized methods include dynamic echocardiography, magnetic resonance imaging, invasive microvascular resistance measurements, histology, cellular calcium-signaling and magnetocardiography as well as molecular genetic expression analysis (miRNA based).
