The investigators studied the relations between coronary angiography (CAG), intravascular ultrasound (IVUS) and fractional flow reserve (FFR) in coronary ostial lesions.
Angiographic evaluation for ostial lesions is reported to be inaccurate in the assessment of the functional and clinical significance of a lesion. The investigators studied the relations between coronary angiography (CAG), intravascular ultrasound (IVUS) and fractional flow reserve (FFR) in coronary ostial lesions.
