Summary

The investigators studied the relations between coronary angiography (CAG), intravascular ultrasound (IVUS) and fractional flow reserve (FFR) in coronary ostial lesions.

Detailed description

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.

Conditions

• Coronary Artery Stenosis

Interventions

Type	Name	Description
DEVICE	Fractional flow reserve	Fractional flow reserve measured by pressure wire
DEVICE	IVUS	intravascular ultrasound :IVUS was performed in a standard fashion using an automated motorized pullback system (0.5mm/s) with commercially available imaging catheter
