BACKGROUND/PURPOSE - Layered pattern (presumed to be healed plaque after a thrombotic event) can be observed by optical coherence tomography (OCT). We sought to assess the ability of OCT-detected plaque composition to predict acute side branch (SB) occlusion after provisional bifurcation stenting. METHODS - This is a retrospective observational study using pre-intervention OCT in the main vessel to predi...

BACKGROUND - The use and clinical outcomes of fractional flow reserve (FFR) measurement in patients with stable ischemic heart disease (SIHD) are uncertain, as prior studies have been based on selected populations. OBJECTIVES - This study sought to evaluate contemporary, real-world patterns of FFR use and its effect on outcomes among unselected patients with SIHD and angiographically intermediate stenose...

BACKGROUND - Mitral leaflet enlargement has been identified as an adaptive mechanism to prevent mitral regurgitation in dilated left ventricles (LVs) caused by chronic aortic regurgitation (AR). This enlargement is deficient in patients with functional mitral regurgitation, which remains frequent in the population with ischemic cardiomyopathy. Maladaptive fibrotic changes have been identified in post-myocardial infarction (MI) mitra...

Transcatheter left atrial appendage occlusion is an increasingly used alternative to oral anticoagulation in selected patients with atrial fibrillation. Pre-procedural imaging is a prerequisite to a successful intervention, with transesophageal echocardiography as the current gold standard. However, cardiac computed tomography offers improved imaging with high-quality multiplanar and 3-dimensional reconstructed images. Nevertheless, the lack of a standardiz...

OBJECTIVES - The aim of this study was to examine whether hospital surgical aortic valve replacement (SAVR) volume was associated with corresponding transcatheter aortic valve replacement (TAVR) outcomes. BACKGROUND - Recent studies have demonstrated a volume-outcome relationship for TAVR. METHODS - In total, 208,400 fee-for-service Medicare beneficiaries w...

OBJECTIVES - The authors used the British Cardiovascular Intervention Society (BCIS) national percutaneous coronary intervention (PCI) database to explore temporal changes in the use of intravascular imaging for unprotected left main stem PCI (uLMS PCI), defined the associates of imaging use, and correlate clinical outcomes including survival with imaging use. BACKGROUND - Limited registr...

Coronary CT Angiography in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome
Clinical Trial | By JJ Linde, H Kelbæk, KF Kofoed et al.
BACKGROUND- In patients with non–ST-segment elevation acute coronary syndrome (NSTEACS), coronary pathology may range from structurally normal vessels to severe coronary artery disease. OBJECTIVES- The purpose of this study was to test if coronary computed tomography angiography (CTA) may be used to exclude coronary artery stenosis ≥50% in patients with NSTEACS. MET...

OBJECTIVES - The aim of this study was to investigate the long-term impact of SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score (SS) on differential outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main coronary artery (LMCA) disease. BACKGROUND - The very long term prognostic effe...
