Coronary computed tomography angiography for clinical practice

Japanese Journal of Radiology
AbstractCoronary artery disease (CAD) is a common condition caused by the accumulation of atherosclerotic plaques. It can be classified into stable CAD or acute coronary syndrome. Coronary computed tomography angiography (CCTA) has a high negative predictive value and is used as the first examination for diagnosing stable CAD, particularly in patients ...

The influence of delayed ventricular activation on cardiac repolarization: Insights from electrocardiographic imaging

The Journal of Physiology, EarlyView.
Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, EarlyView.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.

Coronary Computed Tomography Angiography After Stress Testing

Journal of the American College of Cardiology, 2012
In the ACIC (Advanced Cardiovascular Imaging Consortium) registry, Chinnaiyan et al. ([1][1]) evaluated the correlation between stress test results and extent of coronary artery disease (CAD) on coronary computed tomography angiography (CCTA) and compared the diagnostic performance of ...

Computational model of haemodynamics during atrial fibrillation

The Journal of Physiology, EarlyView.
Abstract figure legend We developed a simplified computational model that replicates patient‐specific haemodynamics during both normal sinus rhythm and atrial fibrillation (AF). Our computational model comprises: (1) an electrical subsystem that generates unco‐ordinated atrial and irregular ventricular activation times characteristic of AF and (2) a ...

The Clinical Utility of a Precision Medicine Blood Test Incorporating Age, Sex, and Gene Expression for Evaluating Women with Stable Symptoms Suggestive of Obstructive Coronary Artery Disease: Analysis from the PRESET Registry. [PDF]

, 2019
Background: Evaluating women with symptoms suggestive of coronary artery disease (CAD) remains challenging. A blood-based precision medicine test yielding an age/sex/gene expression score (ASGES) has shown clinical validity in the diagnosis of ...

Respiratory Motion‐Corrected Model‐Based 3D Water‐Fat MRA of the Thorax at 0.55 T

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3241-3252, June 2026.
ABSTRACT Purpose The goal of this study was to develop a 5‐min 3D MRA acquisition at 0.55 T with predictable scan time, 100% data efficiency, and robust water‐fat separation. Methods For full data efficiency, the proposed method combined self‐gating with retrospective motion correction while ensuring a predictable 5‐min scan time.

Emergency PCI and TAVR for Acute Myocardial Infarction in Severe Aortic Stenosis Patients

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Transcatheter aortic valve replacement (TAVR) is a viable alternative for patients with symptomatic severe aortic stenosis. Acute myocardial infarction is a contraindication to TAVR. The efficacy of emergency TAVR combined with percutaneous coronary intervention for patients presenting with acute myocardial infarction, severe aortic stenosis ...
