Interventional & Structural Heart Cardiologist at UCHealth
Dr. Tuttle is an interventional and structural heart cardiologist specializing in minimally invasive procedures for coronary artery disease, valvular heart disease, and other structural heart conditions. He emphasizes individualized care plans, evidence‑based therapies, and collaborative decision‑making with patients and their families.
Expertise includes complex percutaneous coronary intervention (PCI), transcatheter aortic valve replacement (TAVR), mitral edge‑to‑edge repair (MitraClip), left atrial appendage occlusion (LAAO), and advanced imaging‑guided interventions.
Catheter‑based options tailored to each patient
Balloon angioplasty, drug‑eluting stents, physiologic assessment (FFR/iFR), and intravascular imaging (IVUS/OCT) for precise, durable outcomes.
Transcatheter aortic valve replacement (TAVR), mitral edge‑to‑edge repair (MitraClip), and evaluation for tricuspid therapies as appropriate.
Left atrial appendage occlusion (LAAO), PFO/ASD closure, and catheter‑based solutions for select structural conditions.
From coronary blockages to complex valvular disease

Advancing care through innovation
Dr. Tuttle serves as Site Principal Investigator for the JOURNEY trial (NCT06455787). Patients interested in research opportunities may inquire during clinic visits to learn about eligibility and participation. View study details on ClinicalTrials.gov.
PROGRESS evaluates management of moderate aortic stenosis by clinical surveillance or transcatheter aortic valve replacement (TAVR). View study details on ClinicalTrials.gov.
Prevail Global evaluates the clinical safety and efficacy of the Prevail drug-coated balloon for in-stent restenosis and de novo small vessel coronary disease. View study details on ClinicalTrials.gov.
Helpful details before your visit
Many patients are referred by their primary care or cardiologist, but self‑referrals may be possible. Check with your insurance and the UCHealth team.
UCHealth accepts many major plans; coverage varies by service. The scheduling team can verify your benefits.
Catheter‑based procedures through small incisions — often enabling shorter hospital stays and faster recovery than open surgery.
Urgent cases are prioritized. For elective visits, availability depends on clinic location and the type of evaluation needed.
