Vegetation Formation and Aortitis as a Possible Sequela of COVID-19 in a Patient with an Aortic Stent: A Case Report.

Bacteria, especially staphylococcal groups, cause aortic graft infection. Infection stems from synthetic materials that repair aneurysms or artery blockages. Aortic stent infection and vegetation formation are rare, and heterogeneous presentations and ambiguous findings in routine diagnostic modalities render the diagnosis challenging.

Novel Aortic Valve Replacement Technique for Reducing Complete Heart Block.

Background: Aortic valve replacement (AVR) may complicate conduction abnormalities and require permanent pacemaker (PPM) implantation. New techniques that lessen this challenge may lead to the development of new approaches. Our objective was to evaluate the contemporary incidence of early postoperative PPM implantation in patients undergoing isolated AVR and root disease with the standard AVR surgical technique compared with the novel suture AVR technique.

Massive primary pulmonary artery rhabomyosarcoma: A case report.

Background: Pulmonary artery sarcomas (PAS) are rare tumours causing an insidiously progressive obstruction of the pulmonary circulation. The clinical presentation is often indistinguishable from chronic thromboembolic pulmonary hypertension (CTEPH). However, the atypical appearance of a heterogeneous filling defect in CT pulmonary angiography (CTPA) should prompt further investigation.

Laser-Produced Cavitation Bubble Behavior in Newtonian and Non-Newtonian Liquid Inside a Rigid Cylinder: Numerical Study of Liquid Disc Microjet Impact Using OpenFOAM.

This study employs OpenFOAM to analyze the behavior of a single laser-produced cavitation bubble in a Newtonian/non-Newtonian fluid inside a rigid cylinder. This research aimed to numerically calculate the impact of liquid disc microjet resulting from the growth and collapse of the laser-produced bubble to the cylinder wall to take advantage of the cavitation phenomenon in various industrial and medical applications, such as modeling how to remove calcification lesions in coronary arteries. In addition, by introducing the main study cases in which a single bubble with different initial conditions is produced by a laser in the center/off-center of a cylinder with different orientations relative to the horizon, filled with a stationary or moving Newtonian/Non-Newtonian liquid, the general behavior of the bubble in the stages of growth and collapse and the formation of liquid disk microjet and its impact is examined.

The effect of conjugated linoleic acid supplementation on oxidative stress markers: A systematic review and meta-analysis of randomized controlled trials.

The present systematic review and meta-analysis aimed to investigate the effect of CLA supplementation on oxidative stress parameters.

Methods: We searched PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar databases until September 2021 to identify randomized controlled trials (RCTs) assessing CLA supplementation effects on oxidative markers including malondialdehyde (MDA), 8-isoprostanesF2α (8-iso-PGF2α), and glutathione peroxidase (GPx).

Carotid artery stenting prior to coronary artery bypass grafting in patients with carotid stenosis: Clinical outcomes.

Objectives: Management of patients undergoing coronary artery bypass grafting (CABG) with obstructive disease of the carotid arteries is still a matter of debate. We compared the results of staged carotid artery stenting (CAS) before CABG in patients with carotid lesions.

Materials And Method: Patients with significant carotid artery disease who were deemed to simultaneously suffer from an obstructive coronary artery disease requiring CABG from 2008 to 2018 were screened and enrolled in this study.

Outcome of Surgery for Chronic Thromboembolic Pulmonary Disease without Pulmonary Hypertension.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious condition that results from incomplete resolution of thromboemboli in pulmonary arteries. Symptomatic patients with chronic thromboembolic disease may have normal hemodynamic at rest. The aim of this study is to evaluate the outcome of pulmonary endarterectomy (PEA) in symptomatic patients with chronic thromboembolic pulmonary disease (CTEPD) in the absence of pulmonary hypertension as currently defined (mean pulmonary artery pressure [mPAP] < 20 mm Hg).

A novel inflammatory signaling pathway in patients with slow coronary flow: NF-κB/IL-1β/nitric oxide.

Purpose: The slow coronary flow (SCF) was identified as delayed opacification of epicardial coronary arteries in the absence of stenotic lesion. Metabolic syndrome (MetS), oxidative stress, and inflammation may be possible known insulting factors for the pathogenesis of SCF. This investigation aimed to assess the relationship between some inflammatory markers, oxidative stress parameters and MetS components with SCF phenomenon.

Construction and Development of a Cardiac Tissue-Specific and Hypoxia-Inducible Expression Vector.

Cardiovascular gene therapy is a sophisticated approach, thanks to the safety of vectors, stable transgene expression, delivery method, and different layers of the heart. To date, numerous expression vectors have been introduced in biotechnology and biopharmacy industries in relation to genetic manipulation. Despite the rapid growth of these modalities, they must be intelligently designed, addressing the cardiac-specific transgene expression and less side effects.

The frequency of initial misdiagnosis of acute aortic dissection in the emergency department and its impact on outcome.

We determine the frequency of initial misdiagnosis and inappropriate treatment with antiplatelets/anticoagulants in the emergency department (ED) and the resultant clinical outcomes in patients with acute type A aortic dissection (AAOD). Medical records of patients with a final diagnosis of AAOD admitted from March 2004 through October 2015 to our tertiary-level heart hospital were evaluated. Patients with suspected dissection in ED were compared to those with initial misdiagnosis regarding demographics and clinical presentation, laboratory and echocardiographic findings.

Electrocardiography changes in acute aortic dissection-association with troponin leak, coronary anatomy, and prognosis.

Methods: We retrospectively analyzed the electrocardiograms of patients with AAOD admitted from March 2004 to March 2015. The frequency of ECG findings and their prognostic value on hospital and follow-up mortality were investigated.

Simultaneous operation of hydatid cyst of the heart and liver: a case report.

Primary echinococcosis of the heart is exceptionally uncommon and is reported 0.5% to 2% of all hydatid cyst sites in comparison with liver (70%) or lung (20%) involvement. Hydatid disease of the heart is caused by the cestode tapeworm echinococcosis granulosis or alveolaris.

Evaluation of Early and Intermediate Outcomes of Cryo-MazeProcedure for Atrial Fibrillation.

Introduction: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in patients with mitral valve disease affecting 50% of patients undergoing mitral valve surgery, contributing to increased risks of systemic embolization, anticoagulant- related hemorrhage and mortality. The maze procedure is an effective way to treat AF. Over the last several years, cryoablation was substituted for atrial incision in many reports to simplify the maze procedure.
