Prevalence of anomalies and variants of coronary arteries: A single center study by coronary CT angiography.
Clin Imaging
December 2024
Mersin University, Faculty of Medicine, Department of Anatomy, Mersin, Turkey.
Purpose: It has been demonstrated that the coronary artery anomalies (CAAs) are generally asymptomatic. However, some cases can cause severe life threatening events. As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative to invasive coronary angiography for the evaluation of coronary anatomy, the prevalence of CAAs in CCTA may more closely reflect the true prevalence in the general population.

December 2024
Department of Echocardiography, State Key Laboratory of Cardiovascular Disease, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, 100006 Beijing, China.
Background: Quantitative flow ratio (QFR) can identify functionally significant coronary disease non-invasively. Myocardial contrast echocardiography (MCE) is a non-invasive and effective procedure for detecting abnormalities in hemodynamic coronary artery stenosis. Currently, there is no research confirming the correlation between MCE and QFR.

December 2024
Department of Radiology, Shaoxing Second Hospital, Shaoxing, Zhejiang, China.
Introduction: Retroperitoneal hematoma with ongoing hemorrhage is a rare but critical condition following blunt abdominal trauma, requiring urgent evaluation and management. This case details a large retroperitoneal hematoma in the right iliac fossa caused by a rupture of the deep circumflex iliac artery (DCIA), successfully treated with transcatheter arterial embolization.
Case Description: A 66-year-old female presented to our hospital six hours after an electric tricycle accident with dizziness, fatigue, hypotension (80/50 mmHg), and tachycardia (105 beats/min).
Differences in coronary microcirculation measurements during regadenoson vs. adenosine - induced hyperemia.
Cardiol J
December 2024
Department of Cardiology and Cardiovascular Interventions, University Hospital, Krakow, Poland.
Background: Little is known about the similarity of microcirculation assessment outcomes performed with regadenoson and adenosine. The aim of the current study was to compare coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) assessment using adenosine and regadenoson, and to evaluate predictors regarding the size of differences.
Methods: 44 patients were enrolled and diagnosed between 2021 and 2023.
Combining computed tomography features of left atrial epicardial and pericoronary adipose tissue with the triglyceride-glucose index to predict the recurrence of atrial fibrillation after radiofrequency catheter ablation: a machine learning study.
Quant Imaging Med Surg
December 2024
Department of Radiology, The Affiliated Hospital of Xuzhou Medical University, Xuzhou, China.
Background: Radiofrequency catheter ablation (RFCA) represents an important treatment option for atrial fibrillation (AF); however, the recurrence rate following surgery is relatively high. This study aimed to predict the recurrence of AF after RFCA using interpretable machine learning models that combined the triglyceride-glucose (TyG) index and the quantification of left atrial epicardial and pericoronary adipose tissue.
Methods: This retrospective study included 325 patients with AF who underwent their first successful RFCA, among whom 79 had confirmed recurrence.
