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 CT-angiography].

Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 2008
Recent advances in computed tomography (CT) has made noninvasive imaging of the coronary arteries possible. Multidetector-CT (MDCT)-scanners capable of visualizing the coronary arteries will be available in most Norwegian hospitals within a few years. If the examinations have acceptable quality, diagnostics of coronary pathology could to some extent be

Progressive Rapid Atherosclerotic Plaque Formation and Early Stent re‐Stenosis in an Untreated CLL Patient; A Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT A 66 year‐old male with a history of hypertension and poor follow‐up for chronic lymphocytic leukemia (CLL) experienced two episodes of non‐ST elevation myocardial infarction (NSTEMI) within a 6 month period. Initial coronary angiography showed two‐vessel disease, and percutaneous coronary intervention (PCI) was performed on the left anterior ...

Prognostic Value of Coronary CT Angiography

JACC: Cardiovascular Imaging, 2013
We read with interest the paper from Andreini et al. ([1][1]) that provided more evidence on the prognostic value of cardiac computed tomography angiography (CTA) in patients referred for evaluation of possible coronary artery disease (CAD), an area of research in need of long term follow up ...

Vertebral Artery Occlusion With Ipsilateral Weakness Due to Ischemic Stroke at the Medulla–Cervical Spinal Cord Junction: A Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Posterior circulation strokes can present with diverse neurological deficits, some of which challenge conventional localization principles. We report a case of a 74‐year‐old male with a history of prior right medullary infarct who presented with recurrent symptoms and was found to have a new medullary acute ischemic stroke in the setting of ...

Coronary cross-sectional area stenosis severity determined using coronary CT highly correlated with coronary functional flow reserve: a pilot study

Scientific Reports
Fractional flow reserve (FFR) is the gold standard for assessing the physiological significance of coronary stenosis. We examined the potential correlation between digitally measured coronary cross-sectional area stenosis using coronary computed ...
