Filter by:Neonates who underwent cardiac surgery with cardiopulmonary bypass almost always require non-invasive respiratory support (NIV) in relay to conventional ventilation. Current nasal interfaces do not generally allow synchronised bilevel ventilation. NIV-NAVA mode allows, through an oesophageal catheter, to record the electrical activity of the diaphragm and thereby synchronize breaths from the ventilator on the inspiratory efforts of the child. Moreover, the pressure support delivered by the ventilator may be proportional to the diaphragmatic effort developed by the child. This mode, associated with the interface Miniflow®, could increase the comfort of the child by allowing a more efficient synchronization and reducing its respiratory work. To our knowledge, this ventilation mode with this interface has not been evaluated in the postoperative period of cardiac surgery in the newborns. The purpose of this study is to evaluate the feasibility of this ventilatory mode and evaluate its influence on ventilatory parameters of this category of infants.
The purpose of this study is to evaluate performance of the Vanguard 360 revision knee system utilizing offset on either the tibial component, femoral component, or both in terms of the restoration of mechanical alignment, clinical outcomes and survivorship.
Aims: We plan to investigate how common uterine malformations are in high-risk women (with history of miscarriage or preterm delivery), by analysing different characteristics in these groups. This study will also investigate other ultrasound characteristics detected on these women. This study will point towards the possible mechanism of how uterine malformations may affect pregnancy outcomes.
Exercise intolerance is a major burden for patients with complex congenital heart disease (CHD), significantly affecting their quality of life. Cardiopulmonary exercise testing provides a reliable tool both for assessing exercise capacity of CHD patients and for risk stratification and is becoming part of the routine clinical assessment of these patients. Exercise has an effect on the muscular, metabolic and circulatory systems. While exercise training has been widely studied in chronic heart failure, its efficacy in adults with CHD remain unknown. The investigators hypothesize that structured exercise training will improve exercise intolerance, in particular peak VO2. The aim of this multicenter, randomized study is to evaluate the impact of structured exercise training on exercise intolerance in patients with complex CHD.
The aim of this single center study is to measure the impact of standardized neonatal pediatric surgeries due to gastrointestinal malformations on the children's motor and cognitive development and psycho-emotional competence. To measure the neurodevelopment, the children will be tested with the Bayley Scales of Infant Development II Assessment.
Clinical oedema is seen after open heart surgery with the use of cardiopulmonary bypass and hypothermia in children. The oedema formation is due to increased fluid transport from blood to tissue. This transcapillary fluid transport is dependent on differences in interstitial and plasma colloid osmotic pressure. The purpose of this investigation is to evaluate changes in interstitial colloid osmotic pressure before, under and after the use of cardiopulmonary bypass in children. The study hypothesis is that oedema developed during cardiopulmonary bypass and hypothermia is caused by increased micro vascular protein leakage and reduced colloid osmotic pressure gradient through the capillary membrane.
Mullerian duct anomalies (MDAs) are relatively common disorders, with a prevalence estimated to be around 2% in the general population, and 6% to 7% in women with a history of recurrent pregnancy loss. Mullerian duct anomalies are associated with recurrent pregnancy loss, intra uterine growth retardation, and preterm labor and birth. The prevalence of preterm birth and pregnancy loss varies with the type of MDA. Patients can benefit from surgery or hysteroscopic interventions like metroplasty based on the type of MDA. Therefore, to optimize patient outcomes, accurate diagnosis and description of MDAs is essential. Magnetic resonance imaging (MRI) is an excellent way of evaluating the uterus for MDAs. MRI, although costly, is less expensive than laparoscopy and hysteroscopy and is non-invasive. Pellerito et all evaluated 26 women with surgically proven MDAs and found that in 24 cases MRI was able to correctly diagnose the MDAs. Therefore MRI is generally considered as a reference standard for uterine evaluation. In a study comparing MRI and endovaginal Two-Dimensional Ultrasound (2DUS), MRI appeared to be more accurate than 2DUS with a sensitivity of 77%, specificity of 33%, and a positive predictive value of 83%. Endovaginal Three-Dimensional Ultrasound (3DUS) is a relatively new technology that creates three-dimensional volumes from a series of two-dimensional images. This technique allows the user to acquire coronal or face-on-view of the uterus which is essential in evaluating the uterus for the presence of MDAs. Kupesic and Kurjak used 3DUS to evaluate 86 patients and found that it had sensitivity of 98.38%, specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 96% in the diagnosis of septate uteri [7]. Endovaginal 3DUS is less expensive, less invasive, and less-time consuming than hysteroscopy or MRI and appears to be a very promising technology for the evaluation of MDAs. 3DUS appears to be at least as accurate as MRI in the diagnosis of MDAs. In addition, 3DUS is less expensive than MRI and in some patients better tolerated. If validated using prospective studies, 3DUS has the potential to become the reference standard for the diagnosis of MDAs.
The investigators will check the feasibility of an intraprocedural vitality diagnostics and the identification of an indication for Percutaneous transluminal coronary angioplasty (PTCA).
The objective of this study is to determine the safety, performance, and effectiveness of the SeptRx IPO PFO Closure System in the treatment of Patent Foramen Ovale (PFO) in patients who are amenable to percutaneous closure of their PFO defects.
This is a pilot study examining tendon collagen, collagen cross-linking, and markers of tendon extracellular matrix metabolism in the Achilles tendon of diabetic patients with ulcerations and amputations of the lower extremity.
