Active clinical trials for "Congenital Abnormalities"

Multi-center, prospective, non-randomized study to evaluate Symphony™ Posterior Cervical System in the setting of surgical treatment of adult cervical deformity.

Evaluate surgical treatment outcomes and identify best practice guidelines for complex adult spinal deformity (ASD) patients treated with minimally invasive approach, including radiographic and clinical outcomes, surgical and postoperative complications, risk factors for and revision surgery rates, and the role of standard work to improve patient outcomes and reduce surgical and postoperative complications.

Acquired heart diseases continue to remain one of the most common causes of cardiac mortality and morbidity. In the Russian Federation, open surgery treatment of acquired valvular heart diseases (AVHD) is performed in more than 40 regions by specialists from 92 healthcare organizations. Treating aortic or mitral valve disease using the "UniLine" biological prosthesis is expected to improve survival rates. Supposedly, in vivo the "UniLine" biological prosthesis will show optimal hemodynamic characteristics and high resistance to structural valve degeneration and infectious damage, thus lowering the risk of dysfunction. Moreover, the risk of repeated intervention due to dysfunction of the "UniLine" bioprosthesis should not exceed the risk of the primary implantation. Supposedly, in the case of dysfunction of "UniLine" bioprosthesis it would be possible to perform repeated replacement using valve-in-valve technique. The aim of the study is to assess the effectiveness, safety, durability of the "UniLine" epoxy-treated prosthesis and the long-term outcome of the treatment of isolated mitral and aortic valve diseases using this prosthesis. In accordance with the objectives and hypothesis, the following data will be analyzed: actuarial and linear survival rates (general and cardiac), non-lethal prosthesis-associated complications, prosthetic dysfunction and repeated interventions. Moreover, in vivo hemodynamic parameters of the prosthesis will be assessed: the area of the effective opening surface, peak and mean gradient of pressure and blood flow velocity. The study will be conducted at the Research Institute of Complex Issues of Cardiovascular Diseases. Study protocol received sponsorship approval and approval by Local Ethics Committee of the Research Institute and Research Coordinating Committee. The study will enroll patients who underwent isolated mitral or aortic valve replacement; transthoracic echocardiography will be conducted in all patients available for in-person visit.

Arteriovenous malformation (AVM) is a tangle of abnormal vessels that can progress through life and cause significant bleeding, deformity, pain, and deficits in day-to-day activities. Surgery is a common treatment option for patients with AVMs where the goal is to safely remove the entire AVM without causing complications. While any surgery has its potential risks, most of the potential modifiable risk factors relate to the AVM's structure, such as the AVM size or presence of high risk structural features seen on scans. The purpose of this pilot study is to see whether taking an oral medication called Trametinib can improve upon the AVM structure in adult patients before their scheduled surgery.

This study is to evaluate the amount of correction of torsional deformity in Blount's disease after coronal plane deformity correction by 8 plate hemiepiphysiodesis.

Implant devices are important tools - their use is essential across a number of orthopaedic indications, including hip conditions, trauma and limb deformity. Given the vital role fixation devices play in maintaining alignment, promoting healthy bone healing and preventing joint degeneration, it is essential to understand the expected lifetime outcomes of these implants, and evaluate their safety and efficacy. Prospective implant efficacy and safety registries are needed to support this endeavour, especially considering new regulatory requirements from the European Union Medical Devices Regulation (EU MDR) in relation to post-market clinical follow-up (PMCF).

Anesthesia-related neurotoxicity in the developing brain is still a concern although evidence in humans is debatable. Moreover, it is unclear whether repeated and/or prolonged exposures are harmless and whether their effects are more pronounced in newborns and infants with brains more vulnerable to injury. One such specific group of patients is children with congenital heart disease (CHD). Nearly, half of the school-age survivors with CHD exhibit neurodevelopmental symptoms. It is thus important to elucidate whether any plausible neurotoxicity of the commonly used anesthetic agents can be observed in this population, and whether specific neuroprotective strategies can be demonstrated within the frame of a randomized controlled trial (RCT). Animal data have shown that dexmedetomidine (DEX) induces neuroprotective effects only at well-adjusted doses. One major issue with trials of anesthetic neurotoxicity is the latency between the conduct of these studies and the assessment of neurodevelopmental outcome. In contrast, the use of biomarkers of neuronal injury could be extremely valuable. Serum Neurofilament Light (NfL) has been shown to be a sensitive and specific marker of neuronal injury and is associated with neurologic outcome of children with various pathologies. The investigators hypothesize that in congenital heart surgery, use of DEX as main anesthetic agent in conjunction with low dose sevoflurane results in less release of serum NfL and is thus potentially less neurotoxic compared to the current standard of care. The hypothesis is tested with a RCT including patients between 0 - 3y undergoing surgery with cardiopulmonary bypass. To avoid any neurotoxicity due to anesthetic overdose, intraoperative burst suppression will be avoided. In addition to postoperative comparison of serum NfL, postoperative electroencephalogram and neurodevelopmental outcome of both groups will be compared taking into consideration the genetic background.

Vaginal aplasia is a congenital anomaly characterized by congenital absence of the vagina with an incidence approximately 1:4,500-6,000. It carries an emotional, sexual, and social embarrassing effect on those women, The primary aim of treatment is creation of a neo vagina for restoration of the ability for vaginal intercourse. There are several techniques for neo vaginal construction with variable satisfaction rates. Most of these procedures are either invasive and technically demanding or require long duration in a very motivated patient

During treatment, cancer patients may experience side effects related to their disease but also to the different treatments they receive. Currently, adverse effects and toxicities are well codified in the oncology community, notably via the NCI CTCAE criteria. Unlike objective data such as a blood sample or a CTscan, a major bias in patient assessment is the subjective assessment of the physician or its team at a given time, which may not reflect the overall situation (for better or worse). Several studies had already highlighted the discrepancies between medical and patient data collection. Self-assessment of symptoms is one way to overcome this bias. Moreover, there are now a large number of solutions that allow to perform these self-assessments at home. Thanks to these tools, there are now two situations, the scheduled evaluation (before a chemotherapy treatment, or after a surgical procedure for instance) and the unscheduled situations, where it is the patient himself who can trigger an evaluation form. These new evaluation methods also allow to take a quality of life approach. Patient-reported outcomes (PROs) is now a valid evidence-based assay to detect patient's symptoms and therefore provide helpful clinical information to healthcare providers. The goal of this study is to go one step further than the previous PROs studies and evaluate the ability to train a machine learning algorithm to detect at-risk situations and lay the foundation for a viable solution for future prospective and randomized trials.

A transitional Urology database was created in parallel with National Spina Bifida registry to follow patients with complex congenital urogenital anomalies and be able to prospectively evaluate them. The investigators obtained the standardized questionnaires to collect long-term data regarding patients' genitourinary status including urine and fecal continence, sexuality, fertility, and pelvic health.
