A comparative study of thoracoscopic left atrial appendage clipping versus stapled resection
CONCLUSIONS: The clipping group demonstrated a higher rate of complete LAA closure compared to the stapled resection group. Close monitoring of patients with residual LAA stumps is essential. Further research with larger cohorts is needed to elucidate impact of residual LAA stump on thromboembolic events.PMID:37734642 | DOI:10.1016/j.athoracsur.2023.09.010

Fibromuscular dysplasia incidentally identified with computed tomography angiography
A 78-year-old woman had presented to the emergency room with altered mental status after the inadvertent consumption of a cannabis product. A stroke workup was initiated, including computed tomography angiography, which demonstrated severe tortuosity and a beaded appearance of her bilateral internal carotid arteries (A/Cover and B). The radiographic imaging findings, including alternating areas of bulging and narrowing, were consistent with fibromuscular dysplasia (FMD; C). The patient denied any history of transient ischemic attack, cerebrovascular accident, amaurosis fugax, or chronic kidney issues.

How to improve the description of superior mesenteric artery occlusions in acute mesenteric ischemia: A new computed tomography anatomic segmentation
Acute mesenteric ischemia (AMI) is an intestinal vascular emergency and one of the most severe ischemic syndromes. For stroke or myocardial infarction, arterial segmentations were proposed as early as 1938 and 1975, respectively. These segmentations - used on a daily basis - made it possible to harmonize practices and standardize neurovascular and coronary studies. There is no such standardization in AMI, but the vital and functional prognostic challenge is of the same order. In addition, the lack of a standardized description of superior mesenteric artery (SMA) lesions limits the interpretation and comparability of the studies.

Primary Aldosteronism
Am Fam Physician. 2023 Sep;108(3):273-277.ABSTRACTPrimary aldosteronism is the underlying cause of hypertension in primary care settings in approximately 6% of cases, and it is even more common in patients with resistant hypertension. However, it is estimated that only about 2% of patients who have risk factors for primary aldosteronism have been formally tested or diagnosed. The first step in the diagnosis of primary aldosteronism is case detection and involves testing patients who are at risk, including individuals with resistant hypertension, as well as those with well-controlled hypertension and a first-degree relative...

Computed tomography angiography-based radiomics model to identify high-risk carotid plaques
CONCLUSIONS: The combined model of the radiomics features of carotid plaques and PVAT and the traditional CTA features significantly contributes to identifying high-risk carotid plaques compared with traditional CTA model.PMID:37711840 | PMC:PMC10498225 | DOI:10.21037/qims-23-158

Clot-based time attenuation curve as a novel imaging predictor of mechanical thrombectomy functional outcome in acute ischemia stroke
ConclusionsThrombus TAC on CTP were found to be a promising new imaging biomarker to predict the outcomes of MT in AIS.Clinical relevance statementThis study revealed that clot-based time attenuation curve based on admission perfusion CT could reflect the permeability and composition of thrombus and, also, provide valuable information to predict the clinical outcomes of mechanical thrombectomy in patients with acute ischemia stroke.Key Points• Two time-attenuation curves distributions achieved strong correlations (|r|= 0.627, p < 0.001) with histopathological results.• The unimodal time-attenuation curve was ...

Development and validation of a nomogram for the risk prediction of malignant cerebral edema after acute large hemispheric infarction involving the anterior circulation
ConclusionOur nomogram based on LASSO-logistic regression is accurate and useful for the early prediction of MCE after LHI. This model can serve as a precise and practical tool for clinical decision-making in patients with LHI who may require aggressive therapeutic approaches.

Association of Coronary Artery Calcium Detected by Routine Ungated CT Imaging With Cardiovascular Outcomes
CONCLUSIONS: Incidental CAC ≥100 was associated with an increased risk of all-cause death and adverse cardiovascular outcomes, beyond traditional risk factors. DL-CAC from routine non-ECG-gated CTs identifies patients at increased cardiovascular risk and holds promise as a tool for opportunistic screening to facilitate earlier intervention.PMID:37704309 | DOI:10.1016/j.jacc.2023.06.040
