Provider Bio

BCH's director of thoracic and cardiovascular surgery, Dr. Bryan Mahan specializes in adult heart disease, including these cardiac conditions and treatments:

  • Aortic aneurysms
  • Aortic root replacement and repair
  • Aortic dissection (successful treatment of this urgent condition)
  • Aortic valve replacement and repair
  • Coronary artery bypass graft (CABG)
  • Complex re-operative surgeries (for instance, a second open heart surgery)
  • Heart infections
  • Lung cancer and other chest diseases requiring surgery
  • Mitral valve replacement and repair
  • Surgical ablation of atrial fibrillation (AFib) - advanced Cox-Maze IV procedure
  • Tricuspid valve replacement and repair

Additional information: Dr. Mahan offers extensive expertise in these innovative cardiac treatments:

Hybrid ablation for difficult-to-treat AFib. Dr. Mahan is one of a handful of heart surgeons in the state performing this advanced, minimally invasive procedure. In this cutting-edge collaborative procedure, the heart surgeon creates scar tissue on the outside of the heart while the electrophysiologist does the same on the inside. The resulting scar tissue blocks damaged electrical pathways that cause AFib's characteristic irregular heartbeat. Patients experience only three small incisions in the chest and a few small punctures in the groin, and generally go home after just one or two nights in the hospital.

Thoracic endovascular aortic repair (TEVAR) for aortic aneurysms. TEVAR repairs the aorta using a stent-graft, a flexible metal coil that seals off the weak part of the aorta and protects it from growing any larger. Since TEVAR only requires small groin incisions, it typically leads to shorter hospital stays and quicker recovery times compared to traditional surgical approaches.

Experience and education: Prior to his arrival in Boulder, Dr. Mahan spent 16 years at Memorial Hospital in Colorado Springs, most of those as director of cardiovascular and thoracic surgery. He also practiced at McLaren Northern Michigan Hospital for 11 years, most of those as director of thoracic and cardiac surgery. Dr. Mahan received his medical degree from Kirksville College of Osteopathic Medicine and completed his residency in cardiovascular and thoracic surgery at Detroit Osteopathic Hospital. He also completed a senior fellowship in cardiac surgery at Cleveland Clinic.
