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

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 ...

Thoracic Aortic Plaque Burden and Prediction of Cardiovascular Events in Patients Undergoing 320-row Multidetector CT Coronary Angiography
CONCLUSIONS: We found that comprehensive non-invasive evaluation of TAPB and CAD has prognostic value in MACE risk stratification for suspected CAD patients undergoing CCTA.PMID:37704429 | DOI:10.5551/jat.64251

Natural History and Sequelae of Penetrating Aortic Ulcer
A man in his 70s with history of tobacco use and hypertension presented for transesophageal echocardiography after a recent diagnosis of ischemic stroke. This demonstrated a moderate right-to-left shunt on Valsalva release and no left atrial appendage thrombus. Assessment of the thoracic aorta revealed a complex penetrating aortic ulcer and saccular aneurysm with thrombus in the distal arch and proximal descending thoracic aorta (Figure). Computed tomography angiography confirmed the presence of multiple penetrating ulcerations with large saccular aneurysms.

Effect of mechanical thrombectomy with and without intravenous thrombolysis on the functional outcome of patients with different degrees of thrombus perviousness
ConclusionPatients with thrombi of lower perviousness were recommended to undergo intravenous alteplase followed by endovascular thrombectomy, and those with thrombi of higher perviousness could undergo thrombectomy alone.

Comparing 5G mobile stroke unit and emergency medical service in patients acute ischemic stroke eligible for t ‐PA treatment: A prospective, single‐center clinical trial in Ya'an, China
ConclusionsOur findings indicate that 5G MSU care significantly reduces the time from symptom onset to stroke diagnosis and intravenous thrombolysis in patients with AIS, resulting in improved functional outcomes compared to EMS care. As China continues its deployment of 5G technology and other digital infrastructures, the adoption of 5G MSU care on a broader scale may eventually supplant traditional stroke treatment approaches.

E-164 Symptomatic developmental venous anomaly thrombosis associated with covid-19 infection
We describe a milder case of DVA thrombosis in the setting of COVID-19 infection presenting with unilateral hemiparesis requiring medical management alone. A 41-year-old female with hypertension who presented with left hemiparesis. Non-contrast computed tomography (CT) of head revealed linear calcifications in the right centrum semiovale consistent with DVA. Magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the right corona radiata adjacent to the vascular abnormality. Extensive workup for other causes of ischemic stroke was unrevealing. Cerebral angiography ruled out arteriovenous shunting and did not ...

Direct current cardioversion practices following percutaneous left atrial appendage closure
DiscussionThere is a widely varied practice pattern of TEE, CCTA, and OAC use with DCCV after LAAC, with a 6% rate of LAT/DRT. LAA imaging before DCCV appears prudent in all cases, especially within 1 year of LAAC, to assess for device position, PDL, and LAT/DRT.

Noninvasive In Vivo Thrombus Imaging in Patients With Ischemic Stroke or Transient Ischemic Attack
CONCLUSIONS: 18F-GP1 positron emission tomography and computed tomography angiography is a novel noninvasive method of identifying in vivo cerebrovascular thrombosis, which holds major promise in understanding the role and origin of thrombosis in stroke.REGISTRATION: URL: https://www.CLINICALTRIALS: gov; Unique identifier: NCT03943966.PMID:37439259 | DOI:10.1161/ATVBAHA.122.318204
