Diagnostic accuracy of non-invasive cardiac imaging modalities in patients with a history of coronary artery disease: a meta-analysis.

Background: The diagnostic performance of non-invasive imaging techniques for detecting obstructive coronary artery disease (CAD) in patients with a history of myocardial infarction or percutaneous coronary intervention has not been comprehensively evaluated. This meta-analysis assesses the diagnostic value of coronary CT angiography (CCTA), CCTA combined with CT perfusion (CCTA+CTP), cardiac MRI (CMR) and single-photon emission CT (SPECT) compared with invasive reference standards.

Methods: We systematically searched PubMed, Embase, Web of Science and the Cochrane Library from 2005 to September 2022 for prospective, blinded studies including populations with ≥50% prior CAD.

The mode of delivery after operative fixation of pelvic ring fractures-a retrospective observational study.

Purpose: The purpose of this study is to investigate whether retained hardware after surgical treatment for a pelvic fracture prior to pregnancy affects the choice of delivery method. The study aims to provide insights into the rates of vaginal delivery and caesarean sections, understanding whether the mode of delivery was influenced by patient preference or the recommendations of obstetricians or surgeons, and examining the rate of complications during delivery and postpartum.

Methods: All women of childbearing age who underwent surgical fixation for a pelvic ring fracture between 1994 and 2021 were identified.
