Pericardial SCUBE1 levels may help predict postoperative results in patients operated on for coronary artery bypass graft surgery.

Cardiovasc J Afr 2021 Jul 5;32:1-5. Epub 2021 Jul 5.

Cardiovascular Surgery Department, Trakya University, Edirne, Turkey.

Introduction: Signal peptide-CUB epidermal growth factorlike domain-containing protein (SCUBE1) is a newly described, secretable and measurable cellular surface protein associated with atherosclerotic lesions in humans, which may be involved in hypertension and cardiovascular pathologies. We aimed to detect normal SCUBE1 levels in pericardial fluid and investigate the effects of SCUBE1 values on postoperative outcomes after coronary artery bypass surgery.

Methods: Between February 2016 and March 2017, 184 consecutive patients were included in the study. Read More

Cardiac Surgery Unit, Department of Experimental and Clinical Medicine, University of Florence, Firenze, Italy.

Ischemic stroke after coronary artery bypass (CABG) has been often linked to aortic manipulation during surgery. The objective of the study was to estimate the rate of postoperative ischemic stroke within 30 days from CABG by surgical risk factors alone or in combination. The multinomial propensity score for multiple treatments was used to create six models with a total of 16,255 consecutive patients undergoing isolated CABG. Read More

Right aortic arch with mirror image branching found incidentally during coronary surgery.

SAGE Open Med Case Rep 2021 9;9:2050313X211030014. Epub 2021 Jul 9.

Department of Cardiothoracic Surgery, Heart Hospital, Doha, Qatar.

Right aortic arch with a left innominate (brachiocephalic) artery with mirror image branching (RAMI) is a rare congenital anomaly, and it is unusual to diagnose it in adulthood. There are very few cases of cardiac surgery being performed for acquired cardiac disease on a congenital RAMI patient.

Radial artery as a second conduit gains momentum: The RAPCO trial.

Glob Cardiol Sci Pract 2021 Jun 30;2021(2):e202110. Epub 2021 Jun 30.

Cardiac Surgery Department, Aswan Heart Centre, Aswan, Egypt.

In coronary artery bypass grafting (CABG), the use of an internal mammary artery (IMA) to graft the left anterior descending coronary artery (LAD) improves survival and reduces the need for repeat revascularization. The other IMA, radial artery (RA), and saphenous vein (SV) have contested to complete the surgical revascularization. For that purpose, SV remains the most commonly used conduit despite current evidence in favor of arterial grafts. Read More

Department of Cardiovascular Diseases, Research Unit of Cardiac Surgery, University Hospitals Leuven, Herestraat 49, 3000, Leuven, Belgium.

Background: Poor glycemic control has been associated with an increased risk of wound complications after various types of operations. However, it remains unclear how hemoglobin A1c (HbA1c) and preoperative glycemia can be used in clinical decision-making to prevent sternal wound complications (SWC) following off-pump coronary artery bypass grafting (OPCAB).

Timing of Nonculprit Percutaneous Coronary Intervention after ST-Elevation Myocardial Infarction.

Cardiology 2021 Jul 20:1-10. Epub 2021 Jul 20.

Department of Cardiology, Rabin Medical Center, Petach Tikva, Israel.

Introduction: Complete revascularization of ST-elevation myocardial infarction (STEMI) patients with multivessel disease (MVD) has recently shown to reduce risk of adverse cardiovascular events, including cardiovascular death. Optimal timing of revascularization of nonculprit lesions remains controversial. We aimed to measure cardiac outcomes related to duration between primary percutaneous coronary intervention (pPCI) of the culprit lesion and staged PCI (sPCI) of nonculprit lesions. Read More

A Fluorescence Assay for Evaluating the Permeability of a Cardiac Microvascular Endothelial Barrier in a Rat Model of Ischemia/reperfusion.

J Vis Exp 2021 Jun 30(172). Epub 2021 Jun 30.

State Key Laboratory of Cardiovascular Disease, Department of Cardiology, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College;

Revascularization therapies for culprit arteries, regardless of percutaneous coronary intervention and coronary artery bypass grafting, are considered the best strategy for improving the clinical prognosis of patients with acute coronary syndrome (ACS). Nonetheless, myocardial reperfusion following effective revascularization can trigger significant cardiomyocyte death and coronary endothelial collapse, known as myocardial ischemia/reperfusion injury (MIRI). Usually, endothelial cells and their intercellular tight junctions cooperatively maintain the microvascular endothelial barrier and its relatively low permeability but fail in reperfusion areas.
