Our Approach and Expertise

Michael Borger, MD, PhD, Surgical Director, Aortic Surgery Program at NewYork-Presbyterian/Columbia University Medical CenterOur multidisciplinary group is dedicated to the medical and surgical management of complex aortic disease. We offer expertise in all types of acute and chronic aortic problems including:

  • Aortic root reconstruction,
  • Valve-sparing aortic root replacement,
  • Aortic valve repair,
  • Thoracic aortic aneurysms,
  • Aortic dissection,
  • Mechanical and biological valve conduits, and
  • Minimally invasive methods of aneurysm repair

At NYP/Columbia's Aortic Surgery Program, we offer cutting-edge surgical care for both elective and emergency aortic procedures. We are actively researching the causes of, and new treatment alternatives for, serious aortic disease. We offer long-term follow up care, particularly for patients with residual dissections or connective tissue disorders.

Hiroo Takayama, MDIsaac George, MDWe also offer definitive management of thoracoabdominal aortic reconstruction (endovascular stent grafting and open repair).

Facts about the Columbia Aortic Surgery Program:

  • Mortality for aortic valve replacement at NYP/Columbia is consistently well below the national average for U.S. academic medical centers.
  • The David procedure (Valve sparing root replacement): Columbia is a national leader in conducting this valve-sparing operation, in which the ascending aorta is replaced without harming the native valve. Since 2005, we have performed more than 250 valve sparing procedures with no mortalities in elective cases. Read more.
  • Surgeons in our program have developed a novel minimally invasive aortic arch replacement. This hybrid endovascular procedure involves a shortened and minimally invasive means of both surgical repair and thoracic stent grafting, and can solve complex aneurysmal problems during a single trip to the operating room. 

The Aortic Surgery Program collaborates closely with physicians in the Center for Interventional Vascular Therapy. This collaborative relationship has facilitated the development of novel procedures that are significantly improving patient care.
