Background: Tissue-tracking mitral annular displacement (TMAD) by speckle-tracking echocardiography provides rapid and simple assessment of left ventricular (LV) longitudinal deformation. The purpose of this study was to evaluate the value of TMAD for the assessment of LV longitudinal deformation in patients with severe AS and preserved LV ejection fraction (LVEF).
Methods: We studied 44 patients with severe AS preserved and LVEF in whom TMAD was assessed.
Background: Application of speckle-tracking echocardiography (STE) provides rapid assessment of tissue-tracking mitral annular displacement (TMAD). We investigated the value of TMAD for the assessment of decreased LV longitudinal deformation in asymptomatic patients with severe or moderate-to-severe mitral regurgitation (MR) and preserved LV ejection fraction (LVEF).
Methods: We retrospectively studied 50 patients with severe or moderate-to-severe organic MR and preserved LVEF (>60%) in whom global longitudinal strain (GLS) was successfully measured by STE.
Article Synopsis
- This study aimed to evaluate how well optical coherence tomography (OCT) can match histopathology results in identifying healed coronary plaques (HCPs) in human arteries and to look at the prevalence of these plaques in real patients.
- In an ex vivo analysis of 144 cross-sections from arterial samples, OCT showed high sensitivity (81%) and specificity (98%) in detecting HCPs, while the clinical study found that 77% of patients had OCT-derived HCPs.
- The findings suggest that OCT is effective for identifying HCPs in both lab settings and in patients, highlighting its potential as an imaging tool for assessing coronary health in stable ischemic heart disease.
Background: Although about half of patients with spontaneous coronary artery dissection (SCAD) face ongoing necrosis, conservative therapy is recommended due to a high complication rate in angiography-guided percutaneous coronary intervention (PCI). The aim of this study was to investigate clinical outcomes of SCAD treated by optical coherence tomography (OCT)-guided PCI.
Methods: This study consisted of consecutive 306 patients with acute coronary syndrome (ACS) who underwent OCT-guided PCI.
Objectives: The aim of this study was to determine the best threshold of postintervention minimum stent area (MSA) assessed by optical coherence tomography (OCT) to predict long-term in-stent restenosis (ISR) for 2.5 mm-diameter everolimus-eluting stents (EES).
Background: Percutaneous coronary intervention (PCI) for small coronary arteries remains challenging.
