Vascular Medicine and Intervention

Division of Cardiology

The Vascular Medicine and Interventional program within the Division of Cardiology at the University of Colorado School of Medicine is highly involved in the care of patients with a wide spectrum of non-coronary vascular diseases.  Most of our providers are privileged at both the University of Colorado Hospital and the Denver VA Medical Center and include:  William Hiatt, MD; Judy Regensteiner, PhD; R. Kevin Rogers, MD MSc RPVI; Connie Hess, MD RPVI; Steve Waldo, MD RPVI; and Ehrin Armstrong, MD MSc RPVI.  The program at the University is supported by Mia Barbour, RN and Mary Lee Holbrook.  Laura Brannigan, NP supports the program at the Denver VAMC. 

The clinical focus of the Vascular Medicine and Intervention section currently is the outpatient care of all types of vascular disease including occlusive and aneurysmal atherosclerotic diseases (carotid, vertebral, renal, mesenteric, aortic, and peripheral), non-atherosclerotic diseases (fibromuscular dysplasia, complications from vasculitis, and popliteal entrapment), venous diseases (thromboembolic, central venous compressive disorders such as thoracic outlet syndrome and May-Thurner syndrome, and chronic venous insufficiency) and vasospastic disorders such as Raynaud’s.  Vascular Medicine and Intervention also provides inpatient consultation, both at the University of Colorado Hospital and at the Denver Veterans Affairs Medical Center.

We offer exemplary catheter-based, revascularization for a variety of acute and chronic vascular disorders and perform close to 400 endovascular interventions yearly at the University of Colorado Hospital and the Denver Veterans Affairs Medical Center.  These procedures involve the use of all contemporary endovascular devices, including atherectomy, laser, and novel stent designs, with a large proportion of revascularization procedures performed for limb salvage.  Additionally, Vascular Medicine and Intervention is active in carotid stenting, and the University of Colorado is a site for a NIH-sponsored carotid stenting registry, of which Dr. Rogers is the Principal Investigator.  Through this registry, the University of Colorado is able to offer contemporary carotid revascularization with both proximal and distal embolic protection to a wide range of patients.  Finally, the University of Colorado was the 1st site in Colorado and the Mountain West that offered catheter-based renal denervation to patients with resistant hypertension as part of a multicenter, national randomized trial.


Research efforts are led by Dr. William Hiatt, who as President of CPC Clinical Research (an affiliated clinical trials center) is instrumental in the design, execution, and reporting of numerous clinical trials related to vascular disease.   Connie Hess, MD is a clinician-scientist at the CPC, and Kevin Rogers, MD is the site PI for the University of Colorado for a large, randomized trial comparing percutaneous and surgical revascularization for criticial limb ischemia.  The Denver VAMC is a site for numerous trials in peripheral arterial disease and Drs. Armstrong and Waldo are active in outcomes research in this field.
