Medical Studies and Publications

The backbone of my academic work consists of clinical studies that question the results of the techniques we apply in our clinic: minimally invasive and robotic coronary surgery, mitral valve surgery, acute type A aortic dissection, thoracoabdominal and juxtarenal aortic surgery, open surgery after failed EVAR, carotid endarterectomy and prognostic markers in peripheral interventions. Listed below in chronological order are my peer-reviewed journal articles, book chapters and congress presentations published between 2013 and 2025; article titles link to the DOI or the journal page.
