Comparative Analysis of the Feasibility of Myocardial Blood Flow Index Versus CT-FFR in the Diagnosis of Suspected Coronary Artery Disease

Reviews in Cardiovascular Medicine
Background: Using fluid dynamic modeling, noninvasive fractional flow reserve (FFR) derived from coronary computed tomography angiography (CCTA) data provides better anatomic and functional information than CCTA, with a high diagnostic and discriminatory

Comparison of Fractional Flow Reserve and Myocardial Perfusion Imaging in Saphenous Vein Grafts

Catheterization and Cardiovascular Interventions
ABSTRACTBackgroundRevascularization decision‐making for saphenous vein grafts (SVGs) relies on angiographic lesion severity estimation, as studies on fractional flow reserve (FFR) for detecting ischemia in SVGs are scarce.AimsTo compare FFR and quantitative coronary angiography (QCA) of SVGs against myocardial perfusion imaging (MPI) and to establish ...

Diagnostic Agreement and Threshold Correspondence Between Resting Full‐Cycle Ratio and Nicorandil‐Based Fractional Flow Reserve in Intermediate Coronary Stenosis: A Prospective Single‐Center Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background RFR has shown good aggregate agreement with FFR, including in prior Asian cohorts using intracoronary nicorandil. Where RFR‐FFR disagreement is concentrated relative to the FFR 0.80 decision boundary, and how the two binary thresholds correspond, remain incompletely characterized. Methods In a prospective single‐center registry, 300

Cangrelor Dosing, Administration, and Clinical Outcomes for Patients Undergoing Complex and High‐Risk Percutaneous Coronary Interventions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Cangrelor reduces thrombotic events in patients undergoing percutaneous coronary intervention (PCI), with the advantage of rapid onset and offset. However, premature discontinuation may increase the risk of acute thrombosis for patients undergoing complex/high‐risk PCI (CHIP).

Fractional flow reserve calculation optimized by myocardial computed tomography perfusion information

Quantitative Imaging in Medicine and Surgery
Current computed tomography angiography-derived fractional flow reserve (CT-FFR) diagnosis leaves room for improvement in diagnosing coronary heart disease. In this study, the computed fluid dynamics boundary condition optimization method was used to calculate CT-FFR aiming to improve the diagnostic accuracy of CT-FFR for coronary heart disease.The two

One‐Year Clinical Outcomes of Paclitaxel‐Coated Balloon Angioplasty in Patients With and Without Acute Coronary Syndrome: The ALLIANCE Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Real‐world data after percutaneous coronary intervention (PCI) using drug‐coated balloons (DCBs) in acute coronary syndrome (ACS) are limited. Aims We compared 1‐year clinical outcomes after PCI with paclitaxel DCBs between the ACS and non‐ACS patients.

High-resolution magnetic resonance myocardial perfusion imaging at 3.0-Tesla to detect hemodynamically significant coronary stenoses as determined by fractional flow reserve

, 2010
OBJECTIVES: The objective of this study was to compare visual and quantitative analysis of high spatial resolution cardiac magnetic resonance (CMR) perfusion at 3.0-T against invasively determined fractional flow reserve (FFR).

The difficult discussion on the deactivation of implantable cardioverter devices at the end of life: a systematic review

ESC Heart Failure, Volume 12, Issue 2, Page 733-760, April 2025.
Abstract Implantable cardioverter defibrillators (ICDs) reliably prevent death due to life‐threatening arrhythmias; this may become less relevant in people with more severe heart failure who are reaching the end of life (EOL). This review aimed to explore the ICD deactivation process and identify ethical issues, especially around the initiation of ...

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].
