Influence of Anesthetics on Clinical Outcome in Mitral and Aortic Valve Replacement in Adults
Mitral Valve InsufficiencyAortic Valve InsufficiencyAbstract Anaesthetic support for cardiac surgery significantly influences the course of the intraoperative period and the success of the postoperative period. Total intravenous anaesthesia and inhalation anaesthesia are the traditional methods of anaesthesia in cardiac surgery. However, there are few studies assessing the effectiveness of surgical aggression protection in cardiac surgery. Objectives: To study the effect of anesthetics on clinical outcome after mitral and aortic valve replacement in adults. Methods. The data of 75 patients operated in the Cardiosurgery Department of the Medical Center Hospital of the Presidential Administration of the Republic of Kazakhstan were included in the study. All patients underwent mitral, aortic valve replacement/plasty under cardiopulmonary bypass (CPB) conditions. All patients were divided into 3 groups according to the type of anaesthesia: the first (1) group patients anaesthetised with propofol (P), the second group with sevoflurane (S), and the last one is with isoflurane (I). To maintain anaesthesia in Group 1 propofol was used as anaesthetic in a dose of 6 mg/kg/h intravenously on perfusion. In Group 2 the anaesthetic used was sevoflurane in a dose of 1.7-1.9 MAC. Group 3 used isoflurane in the dose of 1.1-1.2 MAC as anaesthetic. Statistical analysis was done by the method of single factor analysis of variance and Kruskal Wallis criterion.
Safety and Efficacy of TP10, a Complement Inhibitor, in Adult Women Undergoing Cardiopulmonary Bypass...
Myocardial IschemiaCoronary Arteriosclerosis2 moreThe purpose of this study is to determine if the study drug (TP10), which blocks complement release, can reduce such side effects of complement inflammation as chest pain or heart attacks and be taken safely in women who undergo cardiopulmonary bypass surgery.
The Effects of Sevoflurane, Isoflurane and Propofol During Cardiac Surgery
Coronary Artery DiseaseMitral Valve Insufficiency1 moreAbstract Anaesthetic support for cardiac surgery significantly influences the course of the intraoperative period and the success of the postoperative period. Total intravenous anaesthesia and inhalation anaesthesia are the traditional methods of anaesthesia in cardiac surgery. However, there are few studies assessing the effectiveness of surgical aggression protection in cardiac surgery. Objectives: To study the effectiveness of body protection against surgical aggression by TIVA and inhalational anaesthesia in cardiac surgery. Materials and methods. The examination and treatment data of 89 patients were included in the study. All patients underwent coronary artery bypass grafting, mitral valve replacement/plasty, aortic valve replacement cardiopulmonary bypass conditions. The patients were divided into 2 groups according to the type of disease: the first (1) group with coronary heart disease. The second (2) group with valvular heart disease. There were 65 patients in the first group and 22 in the second. Both groups were divided into 3 subgroups according to the type of anaesthesia: patients anaesthetised with propofol, with sevoflurane, with isoflurane.
Effect of Anesthetics on Troponin I and С-reactive Protein
Mitral Valve InsufficiencyAortic Valve Insufficiency1 moreAbstract Troponin is one of the cardiac biomarkers and its high level correlates to high risk of cardiac myocytes damage. C-reactive protein (CRP) in cardiosurgery participates in the Systemic Inflammation Response Syndrome, and heart-lung apparatus is a powerful stimulator of the systemic inflammatory reaction. Objective: To assess effect of anesthetics on troponin I and СRP in mitral, tricuspid and aortic valve replacement/plastic in adult. Methods. Single-center prospective randomized controlled clinical study. A total of 95 patients were assigned randomly into three groups according to the type of anesthesia: the first group of 32 patients with propofol, the second group with sevoflurane - 32 patients, and the last - 31 patients were with isoflurane. Levels of the cardiac troponin I were calculated in ng/ml с using a portable fluorometric analyzer I-CHROMAII, manufacture of BoditechMedInc (South Korea). Normal range: <0.04 ng/ml. CRP concentration in plasma has been determined using a biochemical analyzer Biosystems BA-200 (Spanish company, Barcelona) according to the manufacturer's instructions. The normal level of CRP is less than 5 mg/l.
Evaluate the Transcatheter Artificial Aortic Valve and Transcatheter Artificial Heart Values Delivery...
Severe Aortic StenosisAortic RegurgitationThe purpose of this study is to demonstrate that transcatheter artificial aortic valve and transcatheter artificial heart values delivery system is associated with a reduction of all-cause mortality in severe aortic stenosis or insufficiency patients who are high risk or ineligible for aortic valve replacement.
Enable I Long-term Follow-up Study
Aortic Valve StenosisAortic Valve InsufficiencyThis was a prospective, non-randomized, multi-center, non-interventional post-market study. The study was a post-market long-term follow-up study based on the same cohort of patients (148 patients) enrolled in a previous investigational study from March 2007 to December 2009 (ATS 3f Enable™ Aortic Bioprosthesis Model 6000, number S2005) involving 10 European sites. Patient follow-up took place on a yearly basis up to 10 years after the implant/enrollment. The primary objective of this study was to evaluate the safety and effectiveness of the Medtronic ATS Enable Aortic Bioprosthesis during long-term follow-up. As this was an observational study, safety and efficacy data were summarized and described. There was no statistically powered study hypothesis.
Transcatheter Aortic Valve Replacement With Extracorporeal Life System Support
Aortic StenosisAortic Regurgitation1 moreTranscatheter aortic valve replacement (TAVR) has a high risk and a high mortality rate in the treatment of aortic stenosis/regurgitation patients with cardiac insufficiency. The investigators aim to discuss the clinical efficacy of extracorporeal life support system(ECLS) during TAVR procedure in severe aortic lesion under very low ejection fraction (EF).
Conduction Disease After Transcatheter Aortic Valve Replacement
Aortic StenosisHeart Block1 moreThis is a prospective single center Cardiology department observational study. The study aim is to better understand the predictors of high grade conduction abnormalities associated with TAVR such that a more robust evidence-based and universal strategy to manage cardiac conduction disturbances in these patients, which has been elusive, can be developed.
Extravalvular Procedure for Surgical Treatment of Ascending Aorta Aneurism
Ascending Aorta AneurismAortic InsufficiencyThe investigators expect that the using of prothesis with sinuses has more benefits for long term competence and condition of aortic valve than the using of straight prothesis.
