A simple transseptal approach versus the conventional left atrial approach for mitral valve procedures: a retrospective study.

Background: Having good exposure to the mitral apparatus during mitral valve replacement is a vital decision every cardiac surgeon must take. This study was conducted to compare the simple transseptal approach and the conventional left atrial approach for mitral valve procedures, to evaluate the safety and efficacy of the simple transseptal approach during open heart mitral valve procedures, as the conventional left atrial approach may not provide optimal exposure, especially in unfavorable anatomical and operative situations.

Methods: This is a retrospective study.

Cold atmospheric plasma induces the curing mechanism of diabetic wounds by regulating the oxidative stress mediators iNOS and NO, the pyroptotic mediators NLRP-3, Caspase-1 and IL-1β and the angiogenesis mediators VEGF and Ang-1.

It has been demonstrated that cold atmospheric plasma (CAP) accelerates the wound healing process, however the underlying molecular pathways behind this effect remain unclear. Thus, the goal of the proposed investigation is to elucidate the therapeutic advantages of CAP on angiogenesis, pyroptotic, oxidative stress, and inflammatory mediators during the wound-healing mechanisms associated with diabetes. Intraperitoneal administration of streptozotocin (STZ, 60 mg/Kg) of body weight was used to induce type-1 diabetes.

[Amélioration précoce de la fraction d'éjection chez les patients ayant une fraction d'éjection réduite après un pontage coronarien].

Background: Despite advancements in surgical technique, myocardial shield, and postoperative care, Coronary artery bypass grafting (CABG) among patients with reduced ejection fraction (EF) remains a surgical challenge due to their greater postoperative morbidity and mortality. This study aims to determine the early outcome of patients with reduced LVEF undergoing CABG and the improvement in the ejection fraction after revascularization.

Methods: A total of 62 patients with impaired Left Ventricular (LV) systolic function (LVEF = 35-40 %) who underwent isolated On-pump CABG at the Department of Cardiothoracic Surgery in Assiut University Hospitals and who had met the listed inclusion and exclusion criteria were eligible for the study.

Thoracic surgery in Egypt.

General thoracic surgery operations in Egypt are performed mainly by cardiothoracic surgeons and less oftenly by dedicated thoracic surgeons and general surgeons. This is mainly due to the relatively small number of thoracic surgeons in relation to population as only 210 cardiothoracic surgery specialists and 458 consultants are registered with the Egyptian Medical Syndicate (EMS) in a country with a population of more than 100 million people. Thoracic surgeons in Egypt are faced with a number of burdens, including the need to propagate the service to advanced technology infront of the obstacle of limited resources.

Endocarditis in Bovine Vein Grafts in the Pulmonary Position Placed Surgically & Percutaneously.

Infective endocarditis (IE) is one of the major complications following pulmonary valve replacement (PVR). This analysis hopes to evaluate the incidence, outcomes and possible risk factors of IE associated with trans-catheter and surgical placement of a bovine jugular vein (BJV) graft in the pulmonary position. In this single-center retrospective study, all records of trans-catheter and surgical PVR from 3/2010 to 12/2019 were reviewed.

A prospective randomized study to evaluate splanchnic hypoxia during beating-heart and conventional coronary revascularization.

Objective: Cardiopulmonary bypass (CPB) is associated with gut mucosal hypoxia, which may contribute to gastrointestinal complications. We examined gastric mucosal oxygenation together with whole-body oxygen flux in low-risk patients undergoing coronary artery bypass grafting (CABG) with and without CPB.

Methods: Fifty-four patients undergoing primary CABG by the same surgeon were randomized into either on-pump (ONCAB, n=27) or off-pump (OPCAB, n=27) groups.
