Relationship Between Coronary Angiography Findings and Fractional Flow Reserve After Balloon Angioplasty

Korábbi kezelés

• Prior coronary artery bypass surgery

Más betegség

• Clinically unstable or ST-segment elevation myocardial infarction
• Myocardial infarction in the region supplied by the target vessel
• Accompanying primary valve disease requiring treatment
• Accompanying primary heart disease such as dilated cardiomyopathy, hypertrophic cardiomyopathy, or restrictive cardiomyopathy
• Congenital heart disease

Laborértékek

• Left ventricular ejection fraction (EF) less than 30%
• Most recently measured eGFR is less than 30 right before the procedure

Egyéb

• Target lesion with stenosis of less than 50% or greater than 90% of the internal diameter
• Procedure for restenosis within the stent
• Pre-dilation performed on the target lesion before the coronary artery fractional blood flow reserve test
• Target vessel is a blood vessel that supplies collateral circulation for occlusion of other blood vessels (not applicable when the need for collateral circulation has been resolved due to the opening of another vessel occlusion)

• Patients with clinically stable coronary artery disease
• Patients undergoing balloon angioplasty as an interventional procedure (FFR-guided PCI) using coronary artery fractional blood flow reserve for de novo lesions with a standard vessel diameter of 2.25 mm or more under percutaneous coronary angiography (hereafter referred to as coronary angiography)
  • (Note) If there are other lesions in the proximal area and the FFR of the distal lesion is collected, it is included in the selection target regardless of whether or not the proximal lesion was operated on.
