Dr. Koo is an interventional cardiologist and his main research interest is imaging and physiology of coronary artery disease. Dr. Koo is a principal investigator of many domestic and international studies. He has published more than 400 papers in major journals. He was a course director of TCT-AP and is a course co-director of ENCORE course. He has performed series of studies on bifurcation lesions and coronary physiology/imaging which provided important insights in this field. His recent researches on non-invasive hemodynamic assessment using coronary CT angiography and computational fluid dynamics enables the assessment of FFR without invasive procedures and has started a new chapter in the diagnosis of coronary artery disease. This innovation has now been expanded to non-invasive treatment planner and non-invasive assessment for the risk of ACS.
