There are about 1062 clinical studies being (or have been) conducted in Latvia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The objective of the study is to evaluate the safety and performance of the ARTO System in patients with mitral valve regurgitation (MR) associated with congestive heart failure (CHF).
meriT-V is a Prospective,active control open lable clinical trial to compare safety & efficacy of BioMime Sirolimus stent Vs. Xience family of Everolimus stent by random assignment for treatment of coronary artery disease at multiple multinational centres.
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. But patients may have more than one narrowing and studies have shown that not all narrowings need to be treated. To identify the narrowings that need treating cardiologists sometimes quantify the extent of the narrowing by measuring fractional flow reserve (FFR, the ratio of the pressure in the aorta to the pressure downstream of the narrowing).This technique requires the administration of drugs that add cost and time to the procedure and in some countries are simply unavailable. As a result despite the clear health and healthcare costs benefits of FFR its use is limited to less than 5% of procedure. We have developed a new technique called the instantaneous wave-free ratio (iFR) that does not require the administration of drugs for its accurate assessment. It has been approved for use in this indication. This study aims to compare clinical outcomes of patients whose treatment has been guided by iFR to those whose treatment has been guided by FFR. If iFR is found to provide the same clinical outcomes as FFR its adoption will permit the clear benefits of this approach of identifying the coronary narrowings that really need treatment to be applicable to a much larger patient population and further improve healthcare costs.
This registry has been designed as a multicenter, single arm, open label, post-market registry study with consecutive, eligible patient enrollment at each site. All subjects undergoing the Endovascular Aneurysm Sealing System (EVAS) with the Nellix®-System. Subjects will be followed up to discharge discharge, and as per institutional standard of care thereafter through to 5 years (total follow-up commitment). This registry of the Nellix System, which has received the market authorization of the European Union (Conformité Européenne, CE-certification) in a "real world" patient population treated in a multicenter setting will provide an assessment of the generalizability of the approach and System. Up to 300 patients diagnosed with abdominal aortic aneurysm (AAA) who are considered candidates for Endovascular Repair, in up to 30 international centers will be enrolled in the study.
Many elderly patients undergoing surgical procedures already have impaired cognitive (memory/concentration) status. Patients with pre-existing cognitive impairment, or dementia, may benefit from modified anesthesia techniques. It is estimated that one in eight people age 65 and older has Alzheimers disease. More so, nearly half of people that are 85 years or older have Alzheimers disease. Currently, both spinal (regional) and inhalational (general) anesthesia, are used in patients undergoing common urological, orthopedic, and general surgical procedures. Inhalational anesthesia has been associated with higher risk of memory impairment in experimental (animal) and human studies. However, currently, there are simply no large or good enough studies to be sure that inhalational anesthesia is responsible for causing dementia and Alzheimers disease.The proposed study investigates if elderly patients (65 years and older) undergoing spinal anesthesia (patient is awake or slightly sedated) are less likely to develop dementia and Alzheimers disease for up to 2 years after surgery, when compared to inhalational anesthesia (patient is kept asleep with gas anesthetic). The investigators will also test all patients for the presence of apolipoprotein (ApoE-Îμ4 type of gene that is present in 15-20% of patients), and beta-amyloid tau protein (present in cerebrospinal fluid) that are known risk factors for Alzheimers disease. The particular strength of this study is that it takes into account whether the frequency and/or severity of dementia and Alzheimers disease is different in patients with and without these markers. The investigators believe that this study will make a major contribution to better understanding of development of Alzheimers disease.
Patients with stenosis in one or more coronary artery are often treated with a percutaneous coronary intervention (PCI). As part of the PCI treatment a stent is often placed to keep the vessel open over time. The Combo-Stent is a novel stent for use during percutaneous angioplasty. In short, the Combo stent combines a drug eluting technique and an endothelial cell attracting layer. The drug coating is designed to prevent re-narrowing of the stent. The endothelial cell attracting layer is designed to ensure rapid coverage of the stent struts with vascular wall cells. The REMEDEE REGISTRY evaluates the long-term safety and performance of the Combo stent in routine clinical practice. In total 1000 patients will be registered and followed for five years.
The study is designed to confirm safety and efficacy of the SD01 ICD (implantable cardioverter-defibrillator) lead.
This registry is a clinical post-market evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES).
The purpose of this study is to evaluate the benefit of panitumumab in addition to best supportive care compared to best supportive care alone in patients with chemorefractory wild-type KRAS (Kirsten rat sarcoma viral oncogene homolog) metastatic colorectal cancer.
The purpose of this study is to compare the BIOTRONIK Orsiro Drug Eluting Stent System with the Abbott Xience Prime™ Drug Eluting Stent System with respect to in-stent Late Lumen Loss in a non-inferiority study in de novo coronary lesions at 9 months.
