Morphological Parameters of In-stent RESTenosis Assessed and Identified by OCT
The statistical risk of intrastent stenosis has fallen considerably with the emergence of latest generation coated stents (drug-eluting stents: DES). The number and clinical lifespan of stents implanted over the last twenty-five years, however, explain the fact that restenosis remains a not unusual clinical problem which is expressed as a …

Asian Diabetes Outcomes Prevention Trial
The aim of this study is to identify patients with DM at high risk of CVD using elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels (>125pg/mL), and (2) intensify therapy using renin-angiotensin system (RAS) antagonists, beta-blockers and sodium glucose co-transporter-2 inhibitors (SGLT2i) for primary prevention of cardiovascular events in this high-risk …

Complete Functional Assessment of Intermediate Coronary Artery Stenosis Before and After Transcatheter Aortic Valve Implantation (TAVI) in Patients With Severe Symptomatic Aortic Valve Stenosis (CHOICE-FR)
The purpose of the current study is to assess complete coronary physiology (FFR, RFR, CFR, IMR, and CT-FFR) in TAVI candidates with intermediate coronary artery stenosis before and 6 months after TAVI. This aims to determine how TAVI affects coronary blood flow and coronary microcirculatory function after longer-term follow-up, and …

Resting Full-cycle Flow Ratio (RFR) Versus Angiography to Guide Revascularization Strategy in Patients Undergoing Coronary Artery By-pass Grafting (CABG)
Experience learns that grafts placed on vessels with hemodynamically non-significant stenosis often occlude due to competitive antegrade flow. Resting full-cycle Flow Ratio (RFR) is a measurement performed to evaluate the hemodynamic severity of coronary stenosis.

Full Metall Jacket Multilevel Segment
Hypothesis: "Total" endovascular revascularization of a multistory lesion of the iliac-femoral-popliteal segment is safer and a better quality of life is achieved in comparison with hybrid intervention. The lack of damage to the skin avoids complications in the postoperative and remote periods of observation, thereby improving the quality of life
