Ensemble machine learning to predict futile recanalization after mechanical thrombectomy based on non-contrast CT imaging.

Objectives: Despite successful recanalization after Mechanical Thrombectomy (MT), approximately 25 % of patients with Acute Ischemic Stroke (AIS) due to Large Vessel Occlusion (LVO) show unfavorable clinical outcomes, namely Futile Recanalization (FR). We aimed to use a Machine Learning (ML) Non-Contrast brain CT (NCCT) imaging predictive model to identify FR in patients undergoing MT.

Materials & Methods: Between July 2022 and December 2022, 70 consecutive patients with LVO undergoing a complete recanalization (eTICI 3) with MT within 8 h from onset at our Centre were analyzed.

The role of cardiac computed tomography in diagnostic and prognostic assessment of pregnancy related spontaneous coronary artery dissection: a case report.

Spontaneous coronary artery dissection (SCAD) is the most common cause of myocardial infarction during pregnancy or the postpartum period and has a major impact on cardiovascular morbidity and death in pregnant women. A 38-year-old woman with sudden cardiac arrest ten days postpartum urgently underwent coronarography, which showed an intraparietal hematoma of the left anterior descending (LAD) artery. Two days later, coronary computed tomography angiography (CCTA) was performed, which showed the evidence of SCAD in the mid-distal tract of LAD and the presence of transmural ischemic infarction in the apex and mid antero-septal wall in delayed acquisition.

The Impact of Nitroglycerin on the Evaluation of Coronary Stenosis in Coronary-CT: Preliminary Study in 131 Patients.

Background: The sublingual administration of short-acting nitroglycerin (NTG) before coronary computed tomography (CCT) improves the visualization of coronary arteries, causing vasodilatation. The aim of this study was to evaluate whether and how nitroglycerin can influence the concordance between radiologists and cardiologists in the evaluation of vessel stenosis measured in CCT by the former and during the following coronarography by the latter.

Methods: We conducted a retrospective analysis of 131 patients who underwent CCT for cardiac symptoms in 2022, followed by coronarography performed six months later because of significant stenosis revealed by the CCT.

Incidental findings of acute myocardial infarction detected during ECG-gated and nongated thoracic CTA: A report of four cases.

Worldwide, myocardial infarction is a leading cause of mortality and disability. The phrase ``myocardial infarction'' refers to ischemia, which is the outcome of an imbalance in perfusion between supply and demand and results in the death of cardiac myocytes Myocardial ischemia is often diagnosed based on the patient's medical history and electrocardiogram (ECG) findings. Potential ischemic symptoms include a variety of chest, upper extremity, jaw, or epigastric pain or discomfort that typically lasts at least 20 minutes, is diffuse, not positional, not localized, not dependent on movement of the area, and may be accompanied by syncope, dyspnea, or nausea.
