Intravascular Ultrasound-Derived Virtual Fractional Flow Reserve for the Assessment of Myocardial Ischemia

Circulation Journal, 2018
Fractional flow reserve (FFR) is widely used for the assessment of myocardial ischemia. Intravascular ultrasound (IVUS) is an intracoronary imaging method that provides information about lumen and vessel morphology. Previous studies on the expanded use of IVUS to identify functional ischemia have noted an association between anatomy and physiology, but

Hemodynamic Evaluation of Coronary Artery Lesions after Kawasaki Disease: Comparison of Fractional Flow Reserve during Cardiac Catheterization with Myocardial Flow Reserve during ¹³N-Ammonia PET

Journal of Cardiovascular Development and Disease
Coronary artery lesions (CALs) after Kawasaki disease present complex coronary hemodynamics. We investigated the relationship between coronary fractional flow reserve (FFR), myocardial flow reserve (MFR), and myocardial blood flow volume fraction (MBF ...

Impact of incomplete percutaneous revascularization in patients With multivessel coronary artery disease: a systematic review and meta-analysis [PDF]

, 2016
Background: Up to half of patients undergoing percutaneous coronary intervention have multivessel coronary artery disease (MVD) with conflicting data regarding optimal revascularization strategy in such patients.

Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High‐Definition Intravascular Ultrasound in Non‐ST‐Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).

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

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Revascularization 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. Aims To compare FFR and quantitative coronary angiography (QCA) of SVGs against myocardial perfusion imaging (MPI) and to ...

A case of sepsis‐induced cardiomyopathy successfully treated with venoarterial extracorporeal membrane oxygenation

IJU Case Reports, Volume 6, Issue 1, Page 26-29, January 2023., 2023
Introduction Sepsis with concomitant acute pyelonephritis, secondary to urolithiasis, is common. We report a case of sepsis‐induced cardiomyopathy with acute pyelonephritis, successfully managed with venoarterial extracorporeal membrane oxygenation. Case presentation A 64‐year‐old woman presented with fever and disturbed consciousness.

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Reduced exercise capacity is associated with left ventricular systolic dysfunction in long‐term survivors of allogeneic hematopoietic stem‐cell transplantation

Journal of Clinical Ultrasound, Volume 51, Issue 1, Page 5-15, January 2023., 2023
Exercise intolerance is a common complication in long‐term survivors of allogeneic hematopoietic stem‐cell transplantation. In this study, we found reduced oxygen uptake (VO2peak) by cardio‐pulmonary exercise tests to be associated with left ventricular systolic dysfunction by echocardiography.
