INTRODUCTION: Obstructive Sleep Apnea syndrome (OSA) is the most serious consequence of adenoid hypertrophy (AH) and it is one of the most common reasons of nocturnal hypoxia in children. There is some information about the relationship between childhood OSA and atherosclerosis or cardiac diseases. In this study, we evaluated the relationship between, neutrophil-lymphocyte ratio (NLR) and AH which is the most frequent cause leading OSA in children. AIM: Thus we aimed to contribute about subject of preoperative and postoperative NLR values in patients undergoing adenoidectomy that there is limited information...

OBJECTIVES: The use of stem cells in cardiac regeneration is still limited due to low cellular integration and engraftment rates. Consequently, there has been a spurt in research on developing alternative regenerative therapies. Hyaluronic acid (HA) is a major component of the extracellular matrix that is non-immunogenic, and has been implicated in various wound-healing functions such as angiogenesis and inflammation modulation, making it an ideal candidate for regenerative biomaterials...

We report a unique case of a 4-year-old boy with intermediate-type atrioventricular septal defect, cor triatriatum sinister, persistent left superior vena cava, unroofed coronary sinus, and absent right superior vena cava. Persistent left vena cava draining into the unroofed coronary sinus was demonstrated easily using the agitated saline-contrast echocardiography. After conformation with angiographic evaluation, surgery was performed at a single session. Roofing of the coronary sinus with polytetrafluoroethylene patch, mitral cleft repair, tricuspid annuloplasty, atrioventricular defect repair with pericardial patch, and resection of the membrane in the left atrium was succeeded without complication...

BACKGROUND: Brain natriuretic peptide (BNP) is produced in the heart in response to stretching of the myocardium. BNP levels are negatively correlated to obesity, and in obese subjects, a reduced BNP responsiveness has been described. Diet-induced weight loss has been found to lower or to have no effect on BNP levels, whereas gastric banding and gastric bypass have reported divergent results. We studied obese patients undergoing gastric bypass (GBP) surgery during follow-up of 1 year...

BACKGROUND: Preoperative atrial fibrillation (preop-AF) has been associated with poorer early and late outcomes after cardiac surgery. Few studies, however, have evaluated the impact of preop-AF on early and late outcomes after isolated aortic valve replacement (AVR). METHODS: Data obtained prospectively between June 2001 and December 2009 by the Australian and New Zealand Society of Cardiac and Thoracic Surgeons National Cardiac Surgery Database Program was retrospectively analyzed...

UNLABELLED: Five percent of patients on dual antiplatelet therapy after coronary artery stent implantation will need non-cardiac surgery within the first year of therapy, and many more will need surgery later on. A function assay that evaluates platelet reactivity and inhibition by drug therapy is beneficial for such patients. Platelet Mapping assay (PM) using the TEG analyzer was tested in surgical patients. After IRB approval, 60 patients on combined aspirin and clopidogrel therapy were consented and enrolled...

A total of 25 patients undergoing coronary artery bypass grafting (CABG) were included in the study. Patients received statin (20 mg daily) postoperatively for 2 weeks. All analyses were performed at 2 different time points: preoperatively (group 1) and 2 weeks after operation (group 2). Interleukin (IL)-6, IL-8, plasminogen activator inhibitor 1 (PAI-1), tumor necrosis factor α (TNF-α), tissue plasminogen activator (t-PA) levels, and tissue factor pathway inhibitor (TFPI) were evaluated. Statin treatment caused a significant reduction in the plasma level of PAI-1 (preop: 15...

A hemodialysis access may lead to cardiac overload (CO) or hand ischemia [hemodialysis access induced distal ischemia (HAIDI). Surgical banding restricts access flow and promotes distal perfusion. Aim of the study was to investigate short- and long-term clinical success of banding in these patient groups. After evaluation using a standard protocol, banding procedures (n = 19) were performed in patients (n = 17) with a hemodialysis access flow > or =2 l/minute or with refractory HAIDI. Various parameters including access flow, digital brachial index (DBI), and symptomatology of hand ischemia using a standard scoring system were determined before and after the operation...

On-pump cardiac surgery is accompanied by complex alterations of hemostasis. The excessive postoperative bleeding has been attributed to acquired platelet dysfunction, impaired plasmatic coagulation, and increased fibrinolysis. The characterization of the hemostatic defects responsible for bleeding is crucial for specific treatment and optimal clinical management of the patient. For rapid determination of platelet-dependent primary hemostatic capacity (PHC), the Platelet Function Analyzer PFA-100 system is available...

OBJECTIVE: Expansion of potential donor pool may be facilitated by using cardiac allografts with long ischemic time. Early graft failure and potential relation to transplant coronary artery disease remains a concern. We sought to evaluate outcomes of heart transplantation in recipients of donor allografts with prolonged ischemia time. METHODS: The study group consisted of 46 (mean age, 52 years) consecutive patients at UCLA from 1994 to 2002 that underwent heart transplantation with ischemia time > 300 min...

PURPOSE: To assess aortic wall compliance as a portent of rupture risk in patients with abdominal aortic aneurysms. METHODS: In this pilot study, 38 patients (32 men; median age 78 years, range 63-95) underwent an ultrasound scan: 20 pre-repair and 24 post-repair (18 endovascular [EVR] and 6 open). Six patients from the pre-repair group were included in a post repair study after EVR. Cine loop images were analyzed offsite using wall tracking software, which measured aortic diameter changes during cardiac cycles...

BACKGROUND: Postoperative (postop) atrial fibrillation (AF) occurs in up to 60% of patients after cardiac surgery, leading to longer hospital stays and increased healthcare costs. Recently, B-type natriuretic peptide (BNP) has been reported to predict occurrence of nonpostoperative AF. This study evaluates whether elevated preoperative (preop) plasma BNP levels predict the occurrence of postop AF. METHODS AND RESULTS: One hundred eighty-seven patients with no history of atrial arrhythmia who had a preoperative BNP level and had undergone cardiac surgery were identified...

The management of patients with coexisting severe carotid and coronary artery disease continues to be controversial. To evaluate the actual risks we have reviewed our experience of 92 patients that underwent simultaneous cardiac surgery and carotid thrombendarterectomy (TEA) over a 10 year period. The mean age was 65 +/- 7 year (41-80), 75% were men. There were 11 REDO cardiac procedures. There were 15 symptomatic and 77 asymptomatic carotid artery stenosis, including 21 with bilateral carotid disease. Mean preop...

Children with foregut cysts of the mediastinum can present at any age with nonspecific respiratory symptoms or dysphagia. Chest radiograph and barium esophagram are recommended for initial evaluation, but they fail to identify some lesions. In other cases, an obvious mass may be confused with a solid neoplasm. We have operated upon 34 infants and children with mediastinal bronchogenic cysts and esophageal duplications from 1968 through 1985. This review of their clinical course and radiographic imaging studies emphasizes some of the diagnostic pitfalls that lead to operative delay...
