CT Coronary Angiography and Computational Fluid Dynamics
CT Coronary Angiography and Computational Fluid Dynamics
Angiographically obtained fractional flow reserve(FFR) could provide functional and clinical
 information about stenotic lesion, but the invasiveness and measuring difficulty of FFR make
 it unfamiliar to perform. CT coronary angiography is non-invasive tool to evaluate lesion
 severity and lately developing computational fluid dynamics could provide functional
 information. The investigators build a patient specific model of computational fluid dynamics
 by CT coronary angiography and evaluate the functional significance by measuring fractional
 flow reserve via CT coronary angiography and computational fluid dynamics, and investigate
 its long-term prognostic implications.
