Knowledge of whole heart anatomy is a prerequisite for many clinical applications. Whole heart segmentation (WHS), which delineates substructures of the heart, can be very valuable for modeling and analysis of the anatomy and functions of the heart. However, automating this segmentation can be chall...

Magnetic resonance (MR) imaging has unparalleled soft-tissue imaging capabilities. The presence of devices such as pacemakers and implantable cardioverter-defibrillators (ICDs), however, was historically considered a contraindication to MR imaging. We summarize the potential hazards of the device-MR...

Regional wall motion abnormalities (RWMA) detected by intraoperative transesophageal echocardiography (TEE) are thought to be sensitive markers of myocardial ischemia. To assess the prognostic significance of RWMA as compared with other less costly technologies such as electrocardiography (ECG) and ...

Objectives The aim of the study was to determine whether left ventricular hypertrophy has an independent adverse effect on survival. Background Left ventricular hypertrophy is considered to be a significant risk factor for coronary heart disease mortality; however, the impact of coexisting coronary ...

Intraoperative segmental wall motion abnormalities (SWMA) detected by transesophageal echocardiography (TEE) are sensitive, but not always specific, markers of myocardial ischemia. To determine their incidence, characteristics, and relation to postoperative cardiac morbidity, we continuously recorde...

Prognosis and therapeutic decisions are often based on left ventricular ejection fraction (LVEF), which means the LVEF needs to be accurately measured. Many imaging modalities can measure LVEF. Each of these modalities is subject to measurement errors that can lead to the inaccurate calculation of L...

UNLABELLED: Iodine-123-free fatty acid analogs, such as beta-methyliodophenylpentadecanoic acid (BMIPP), allow for myocardial metabolic studies with SPECT. The goal of this investigation was to determine whether BMIPP uptake can be used to differentiate viable myocardium from scar tissue soon after ...

Background Patients with chronic kidney disease (CKD) have a high prevalence of coronary artery calcification, suggesting that CKD itself is a risk factor for its occurrence. Existing studies are confounded by the inclusion of patients who may not have CKD by means of diagnostic criteria and by fail...

Hemodynamic parameters have been identified as a significant determinant in the development and progression of plaque, which leads to coronary artery disease (CAD). This study aims to use computational modeling to investigate how geometrical variations influence intravascular and near-wall hemodynam...

Plaque rupture is related to the mechanical stress it suffered. The value and distribution of the mechanical stress in plaque could help on assessing plaque vulnerability. To look into the stress conditions in the coronary artery, a patient-specific coronary model was created by using optical cohere...

Since the four working groups of the Chinese Society of Cardiology issued first expert consensus on coronary microvascular diseases (CMVD) in 2017, international consensus documents on CMVD have increased rapidly. Although some of these documents made preliminary recommendations for the diagnosis an...

Objective To investigate the effect of image quality of coronary CT angiography (CCTA) on the diagnostic performance of a machine learning-based CT-derived fractional flow reserve (FFR CT ). Methods This nationwide retrospective study enrolled participants from 10 individual centers across China. FF...

OBJECTIVE: Our aim was to assess the inter- and intraindividual variability of the attenuation threshold used to identify coronary artery calcification on electron beam CT and to illustrate a new threshold method. MATERIALS AND METHODS: We measured the soft-tissue attenuation of regions surrounding ...

BACKGROUND: To determine whether waist-to-height ratio correlates with coronary artery disease (CAD) severity better, than the body mass index (BMI) as assessed by coronary angiography in Bangladeshi population. METHODS: This cross sectional study was done on patients in Department of Cardiology in ...

Objective The objective was to determine the extent to which effectiveness of cardiac and diabetes treatment strategies varies by patient age. Background The impact of age on the effectiveness of revascularization and hyperglycemia treatments has not been thoroughly investigated. Methods In BARI 2D,...
