Pullback Pressure Gradient (PPG) Global Registry
The purpose of this study is to determine the predictive capacity of the Pullback Pressure Gradient (PPG) index for post-PCI FFR and to determine the impact of the PPG index on clinical decision making about revascularization and on clinical outcomes.
Functional ComprEhensive AssessmenT by IVUS Reconstruction in Patients With Suspected IschEmic Heart Disease (FEATURE)
Investigating the diagnostic accuracy of online Ultrasonic Flow Ratio (UFR) assessment to identify hemodynamically significant coronary stenosis in patients with suspected ischemic heart disease using angiography-derived fractional flow reserve (FFR) as a reference standard.
The Role of Cardiovascular Magnetic Resonance in Patients With Non-ST- Elevation- Myocardial Infarction
The goal of this prospective study is to evaluate the role of cardiovascular magnetic resonance (CMR) in patients with suspected non-ST elevation myocardial infarction (NSTEMI). The main endpoint is the reclassification rate, defined as the number of patients in whom the information provided by pre-angiography CMR affects the revascularization strategy …
A Validation Study of Nitroglycerin Induced Acute Drop of Pd/Pa (NTG-Pd/Pa) in Clinical Practice
Hyperemia with adenosine was an elemental process in FFR examination. Adenosine injection will induce some discomfort, and increase cost expenditure. Nitroglycerine will induce an acute drop of Pd/Pa, and this lowest Pd/Pa was determined as NTG-Pd/Pa. NTG-Pd/Pa has a linear relationship with FFR value and has a good diagnostic accuracy …
Myocardial Injury in Treatment of AAA
Comparison of elective infrarenal aneurysm surgery with open and endovascular technique, respectively, for subclinical ischemic myocardial injury detectable with troponin T and/or 3-channel Holter ECG with ST analysis
GENOSS Coronary Stent Clinical Trial
This study aims to evaluate the efficacy and safety of abluminal biodegradable polymer ultrathin sirolimus-eluting stent (Genoss stent) as compared with a durable-polymer everolimus-eluting stent (Xience stent) in patients with coronary artery disease.
Impact of Dynamic CoROnary RoADmap System for Guidance of Instantaneous Wave-Free Ratio or Fractional Flow Reserve
In patients with 50-90% stenosis of the coronary artery, the coronary roadmap (dynamic roadmap) is performed when the conventional fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are performed. coronary roadmap system) to confirm the effectiveness of the function.
European Registry On Plaque ModifiCAtion in the STEMI Population (ROCA-STEMI)
This is an European prospective cohort study from February 2023 until February 2024. The investigators want to analyze the clinical success, efficacy and safety of consecutive patients who presented with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) for de novo heavily calcified culprit lesion using plaque modification …
A Study of Pressure Waveform Analysis in Coronary Artery-II
The goal of this observational study is to test the feasibility of intracoronary adenosine administration during coronary flow reserve(CFR) and index of microcirculatory resistance(IMR) assessment in a population with angina. The main questions it aims to answer are Repeatability of CFR and IMR assessment while hyperemia with intracoronary adenosine was …
Safety and Clinical Performance of the Yukon Choice PC, Yukon Chrome PC & Yukon Choice Flex Stents in Routine Practice
The goal of this observational study is to collect safety and performance information in the setting of a large-scale clinical registry. Patients meeting the selection criteria will be included, in chronological order of their implantation. This registry does not require any additional procedures, follow-up interventions, or ionizing radiation for patients. …
