Background: The ultimate goal of mitral valve surgery in young women is to extend life expectancy and improve quality of life. Mitral valve replacement (MVR) prosthesis in middle-aged women is a difficult choice between the lifelong anticoagulation by mechanical prosthesis versus the limited long-term durability of bioprosthesis. The current trend towards reducing women’s age for selecting bioprosthesis over mechanical prosthesis leads to a dilemma for younger women decision making. The aim of this study was to compare the safety and freedom from complications in pregnancy and survival rate after mitral valve bioprosthesis versus mechanical prosthesis in young women for whom mitral valve repair is not feasible, or unsuitable. Methods: This single-center non randomized prospective study included all female patients undergoing MVR at our center from January 2010 to February 2020. Results: In total, 355 young women patients underwent MVR at our center, of whom 174 received a bioprosthesis and 181 received a mechanical prosthesis. The use of anticoagulation among young women with mechanical prosthesis was associated with a remarkable risk of postoperative bleeding, abortion, and increased frequency of pregnancy-related complications (P < .0001). In contrast, there was a considerable survival benefit for those who received bioprosthesis (P = .0001). Conclusion: Our data confirm that the use of mitral bioprosthesis in young women who desire to become pregnant is safe, reduces complications, and increases survival.
Background and aim: Extensive diffuse coronary artery total occlusions (CTOs) constitute a challenging surgical problem. Extensive coronary endarterectomy (CE) combined with CABG was suggested as a revascularization technique. It was claimed that previous stenting may affect outcome. The present study aimed to report the outcome of LAD endarterectomy for CTO and to determine the effect of previous stenting on this outcome. Patients and methods: The present retrospective study was conducted on 194 patients with CTO indicated for left anterior descending artery (LAD) endarterectomy. To reduce the bias related to unbalanced patients selection, propensity score matching analysis was used. According to the propensity score, 194 patients were included in the analysis. They comprised 66 patients with previous stent and 128 patients without previous stent. Patients were followed for a median (range) of 74.0 (6.0-149.0) months. The primary study outcome was LAD graft patency. Other outcome parameters included postoperative complications, hospital and ICU stay, and mortality. Results: Comparison between the studied groups regarding outcome parameters revealed no significant differences regarding graft patency (93.9% versus 89.1%; P = .27), graft survival (median [95% CI]: 134.3 months [127.0-141.5] versus 135.2 months [128.4-142.0]; P = .35), patients’ survival (93.9% versus 91.4%) and patients’ survival time (median [95% CI]: 132.3 months [125.0-139.5] versus 138.0 months [132.0-144.1]; P = .75]. Conclusion: The present study supports using CE as an adjuvant technique with CABG in patients with TCOs.

Results: Comparison between the studied groups regarding outcome parameters revealed no significant differences regarding graft patency (93.9 % versus 89.1; p=0.27), graft survival [median (95% CI): 134.3 months (127.0-141.5) versus 135.2 months (128.4-142.0); p=0.35], patients’ survival (93.9 % versus 91.4 %) and patients’ survival time [median (95% CI): (132.3 months (125.0-139.5) versus 138.0 months (132.0-144.1); p= 0.75]. Conclusions: The present study supports use CE as an adjuvant technique with CABG in patients with TCOs.
Kawasaki disease, an acute febrile illness, can cause vasculitis in the coronary arteries. It is the chief acquired cause of myocardial infarction and sudden cardiac death in infants, children, and young adults in developed countries. We report a case of chronic, silent Kawasaki disease complicated by multivessel thrombosis in a 39-year-old Egyptian woman. The patient presented with progressive, unstable angina but was otherwise asymptomatic and at negligible risk of ischemic heart disease. Coronary angiograms showed critical arterial stenosis with multiple aneurysms. During revascularization surgery, the patient's harvested left internal mammary artery was found to have occlusive lesions and aneurysmal areas that made it unfit for bypass grafting, and subsequent histopathologic examination revealed features characteristic of chronic Kawasaki disease–associated systemic vasculitis. We think that this is only the second report of Kawasaki disease in the Arabian Mediterranean region. In addition to the patient's case, we discuss the epidemiology and management of Kawasaki disease, in hopes of increasing clinicians' awareness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
