On the 7th of December we received a very warm welcome by Professor Sebastian Debus and his team at the UKE Hamburg University Vascular Center. We are proud that one of the largest aortic centers of Europe is joining the ACTION-1 study from DLZ and Amsterdam UMC. It was impressive to receive a tour around all facilities, amazing high standards. We are looking forward to include the first patients. Thanks to Meral Ayhan and ‘Prüfarzt’ Karolina Malik as well.
