Angiographic severity of coronary artery stenosis has historically been the primary guide to
revascularization or medical management of coronary artery disease. However, physiologic …

Background Imaging-guided percutaneous coronary intervention (PCI) is associated with
better clinical outcomes than angiography-guided PCI. Whether routine optical coherence …

Importance At present, the choice of noninvasive testing for a diagnosis of significant coronary
artery disease (CAD) is ambiguous, but nuclear myocardial perfusion imaging with single-…

Aims The aim of this study was to determine the diagnostic performance of single-photon
emission computed tomography (SPECT), stress echocardiography (SE), invasive coronary …

Background : The hybrid algorithm for chronic total occlusion (CTO) percutaneous coronary
intervention (PCI) was developed to improve procedural outcomes. Large, prospective …

Outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) have
improved because of advancements in equipment and techniques. With global collaboration …

Background : Fractional flow reserve (FFR) computation from coronary computed tomography
angiography (CTA) datasets (FFR CT ) has emerged as a promising noninvasive test to …

Background : Recent studies have demonstrated improved diagnostic accuracy for detecting
coronary artery disease (CAD) when myocardial blood flow (MBF) is quantified in absolute …

During left ventricular (LV) torsion, the base rotates in an overall clockwise direction and the
apex rotates in a counterclockwise direction when viewed from apex to base. LV torsion is …

Aims Lack of gadolinium-contrast wash-in on first-pass perfusion imaging, early gadolinium-enhanced
imaging, or late gadolinium-enhanced (LGE) cardiovascular magnetic resonance …
