Dr. Ikonomidis’ research interests include myocardial protection and intraoperative interrogation of the myocardium for enzyme and signaling activity. In addition, Dr. Ikonomidis holds NIH grant funding for the study of a murine model of thoracic aortic aneurysms which has led to valuable insights with regard to the signaling and protease milieu present within the developing aneurysm. In addition, Dr. Ikonomidis holds NIH grant funding for the study of a multi-institutional ascending thoracic aortic aneurysm tissue bank, housed at MUSC, which is currently yielding valuable insights regarding the etiology of thoracic aortic aneurysms in patients with different risk factors.
