BACKGROUND & AIMS: Obesity surgery induces beneficial effects in metabolic and cardiovascular parameters. Adiponectin increase might be associated with some of these changes. However, direct comparison between different surgical techniques has not been extensively performed. METHODS: We studied 20 obese women submitted to laparoscopic Roux en Y gastric bypass (RYGB) and 20 to sleeve gastrectomy (SG). Twenty control women matched for age and baseline metabolic profiles were also included...

Mesenchymal stem cells (MSCs) are attractive tools for regenerative medicine because of their multi-differentiation potential and immunomodulation capacity. In congenital heart defect surgical correction, replacement grafts lacking growth potential are commonly used. Tissue engineering promises to overcome the limitations of these grafts. In this study, we hypothesized that human thymus derived MSCs are a suitable tool to tissue engineer a living vascular graft with good integration and patency once implanted in vivo...

Cardiovascular disease remains the number one cause of mortality in the United States. There are numerous approaches to treating these diseases, but regardless of the approach, an in vivo model is needed to test each treatment. The pig is one of the most used large animal models for cardiovascular disease. Its heart is very similar in anatomy and function to that of a human. The ameroid placement technique creates an ischemic area of the heart, which has many useful applications in studying myocardial infarction...

Vascular xenografts are widely used in cardiovascular surgery as an alternative to autologous vessels and vascular allografts. Calcification is one of the main drawbacks of vascular grafts, especially among young patients and children. Among different anticalcification approaches, chitosan emerges as a highly promising candidate due to its versatility, natural origin, and biocompatibility. We investigated the anticalcification efficacy of globular chitosan ("Chitozol") as it demonstrated the improved rate of water solubility as compared with conventional linear macromolecules of chitosan...

Iatrogenic aortic dissection caused by axillary arterial cannulation or perfusion becomes a fatal complication of cardiopulmonary bypass when surgeons do not recognize it in the surgical field of view immediately during surgery. Therefore, we routinely monitor the aorta using 'triple ultrasonography' during cardiovascular surgery. An 85-year-old woman underwent partial arch replacement for chronic type A aortic dissection. During cardiopulmonary bypass, acute aortic dissection was observed in the aortic arch from the right axillary artery on real-time transoesophageal echocardiography...

OBJECTIVES: Numerous studies have shown that elevated red cell distribution width (RDW) is associated with poor outcomes in patients with cardiovascular diseases such as coronary artery disease, peripheral artery disease or stroke. The usefulness of the RDW as a predictor of perioperative stroke in patients with valve disease undergoing valve surgery is currently unknown. The aim of the study was to evaluate the prognostic value of RDW for stroke in the early postoperative period in patients undergoing valve replacement or repair surgery...

Aircrew are responsible for safe and reliable aircraft operations. Cardiovascular disease accounts for 50% of all pilot licences declined or withdrawn for medical reasons in Western Europe and is the most common cases of sudden incapacitation in flight. Aircrew retirement age is increasing (up to age 65) in a growing number of airlines and the burden of subclinical, but potentially significant, coronary atherosclerosis is unknown in qualified pilots above age 40. Safety considerations are paramount in aviation medicine, and the most dreaded cardiovascular complications are thromboembolic events and rhythm disturbances due to their potential for sudden incapacitation...

A 55-year-old morbidly obese woman [body mass index (BMI) 51.2] developed acute type A aortic dissection, and she also presented with significant hypoxemia and hypercapnia. She underwent a successful emergency total arch replacement, but severe hypoxemia persisted and Pao2/Fio2 lowered to 71.9 mmHg. We therefore applied high frequency jet ventilation (HFJV), which soon improved the hypoxemia without hemodynamic compromise. HFJV was discontinued three days later, when her Pao2/Fio2 improved to 170.0 mmHg. Weaning from the respirator was initiated on postoperative day 13...

The number of patients requiring hemodialysis is continuously increasing around the world. Hemodialysis affects patient quality of life and it is also associated with a higher risk for cardiovascular events. In addition to traditional risk factors for cardiovascular events such as hypertension, hyperlipidemia, and diabetes, hemodialysis is associated with hyperphosphatemia, chronic inflammation, vascular calcification, and anemia which accelerate atherosclerosis, vascular stiffness, and cardiac ischemia. Treatment strategy for coronary revascularization in this progressive disease remains controversial...
