Prevalence and Clinical Outcomes of Discordant Lesions Between Fractional Flow Reserve and Nonhyperemic Pressure Ratios in Clinical Practice: The J-PRIDE Registry.

Background: Limited large-scale, real-world data exist on the prevalence and clinical impact of discordance between fractional flow reserve (FFR) and nonhyperemic pressure ratios (NHPRs).

Methods: The J-PRIDE registry (Clinical Outcomes of Japanese Patients With Coronary Artery Disease Assessed by Resting Indices and Fractional Flow Reserve: A Prospective Multicenter Registry) prospectively enrolled 4304 lesions in 3200 patients from 20 Japanese centers. The lesions were classified into FFR+/NHPR-, FFR-/NHPR+, FFR+/NHPR+, or FFR-/NHPR groups according to cutoff values of 0.

Modest dilation using rotational atherectomy and drug-coated balloon for native coronary proximal lesion with patent internal thoracic artery graft.

Unlabelled: Intervention to proximal lesions should be avoided in graft-protected native coronary arteries in general, because there might be a risk for bypass-graft failure. An 81-year-old man with coronary artery bypass grafting surgery due to 3-vessel disease 17 years previously complained of worsening angina. Coronary angiography (CAG) revealed a diseased saphenous vein graft (SVG) and a probable functional occlusion in the mid left anterior descending coronary artery (LAD) concomitant with calcified severe stenosis in the left main (LM)-proximal LAD, and patent right internal thoracic artery (RITA)-LAD graft.

[Development of Image Database for Kiken-yochi Training (KYT) in Radiology Practice].

Kiken-yochi Training (KYT) has been introduced in many hospitals as medical safety education in many departments, with the exception of radiology. KYT is also not used in the contents of medical safety lectures in the education of students for radiological technologists. One of the reasons for this is that the images for KYT (KYT images) cannot be created at each hospital or easily obtained on the website.
