Measurement of Instantaneous Wave-free Ratio through a Diagnostic Catheter: Comparison of the Results between 4Fr and 5Fr

Artery Research, 2020
Background: Clinical evidence of coronary pressure assessment through a diagnostic catheter is limited. The aim of this study was to assess the difference, safety, and rate of successful measurement of Instantaneous Wave-free Ratio (iFR) through 4Fr and ...

Novel Humanized Biosimulator to Predict Coronary Obstruction in High-Risk Valve-in-Valve Procedures

JACC: Case Reports, 2023
We developed humanized biosimulator to predict the risk of coronary obstruction among high-risk patients undergoing valve-in-valve (ViV) procedures. In this case, based on unchanged instantaneous wave-free ratio values measured during a ViV simulation ...

Change in instantaneous wave-free ratio in the donor artery in multivessel coronary disease: a case report

Российский кардиологический журнал, 2022
Patients with multivessel coronary artery disease require an individual approach when choosing tactics for myocardial revascularization. In some cases, additional methods for assessing the stenosis significance should be used, such as measuring the ...

Reliability of Instantaneous Wave-Free Ratio (iFR) for the Evaluation of Left Main Coronary Artery Lesions. [PDF]

J Clin Med, 2019
The assessment of the left main coronary artery (LMCA) by coronary angiography has several limitations. The fractional flow reserve (FFR) is useful for the functional evaluation of LMCA stenoses.
