Profile Headshot


My most important goal in patient care is to advance the overall well-being of each patient. Patients who are undergoing open heart surgery are often scared and quite concerned. While my role is performing a perfect operation and I am confident, I would like to sit down and spend time with each one of these nervous patients and their families so that we develop trustworthy relationship before surgery, during surgery, and after surgery.


Dr. Hiroo Takayama is Chief of Adult Cardiac Surgery at NewYork-Presbyterian/Columbia University Irving Medical Center. He has more than 20 years of experience in treating patients with heart and vascular problems. As the Director of the Aortic Surgery Program and co-Director of the Aortic Center, the Hypertrophic Cardiomyopathy Center, and the Marfan Clinic at NYP/Columbia, Dr. Takayama has contributed to the care of over 4,000 patients by performing a variety of aortic and cardiac surgical procedures, approximately 300-350 operations every year.

Dr. Takayama is internationally recognized for his work on complex aortic surgery (minimally invasive aortic surgery, valve-sparing aortic root replacement, aortic valve repair, aortic arch and thoracoabdominal aneurysm repair), hybrid aortic surgery (thoracic endovascular aneurysm repair), myectomy for obstructive hypertrophic cardiomyopathy, and heart failure surgery.

He is a leader in outcome research in aortic diseases and heart failure. He has published more than 300-350 manuscripts in prestigious, peer-reviewed journals and has authored numerous book chapters about heart disease.

Dr. Takayama attended University of Tokyo for Medical School, did his internship at University of Tokyo, general surgery residency in University of Washington Medical Center, and cardio-thoracic surgery fellowship in New-York Presbyterian/Columbia University Medical Center.
