However, the complications and outcomes of new devices have not been studied enough. Hence, the purpose of this study is to evaluate the midterm results of the Core Valve and Evolute R self-expandable (SE) devices versus the Edwards SAPIEN balloon-expandable (BE) devices. Methods and Material: This was a quasi-experimental study conducted in Tehran, Iran, from May 2012 to June 2017. SAS patients who were not ideal candidates for surgery were randomly assigned to either SE or BE groups. For each patient, a questionnaire, including four sections comprised of Basic characteristics, echocardiographic, angiographic, and Computed Tomography (CT) scan data was filled. TAVI was followed by echocardiography a week later and after three months they were reevaluated by another questionnaire. Results: The total number of patients was 60. The mean ages of patients undergoing the procedure with SE or BE devices were 81.2 ± 8 and 79.8 ± 7, respectively. Mortality occurred in 20% of the patients (5 cases in the SE group and 7 cases in the BE);mortality causes were 66.6 % cardiac and 33% non-cardiac. Moderate to severe Paravalvular leakage in both groups did not differ significantly. The mortality rate was 5 (41.6%) in the SE group versus 7 (58.3%) in the BE group (P > 0.05). Conclusion: In conclusion, the BE group did not experience fewer paravalvular leaks in comparison with the SE. Morbidity and mortality between the BE and the SE groups did not differ significantly.展开更多
文摘研究加速康复理念在TAVI术患者护理配合中的临床价值分析。方法 选取我院2023年1月~2024年1月期间收治行TAVI术患者60例,按照其采用的疗法分为对照组和观察组,每组各30例患者,对照组采用常规干预,观察组在此基础上采用加速康复理念。观察并分析两组患者的简易智能精神状态检查量表(Mini-Mental State Examination, MMSE)评分、镇静催眠评分警觉/镇定评分(observer’s assessment of alertness/sedation,OAA/s)及不良反应发生率。结果 经干预治疗,两组患者评分均有大幅提高,观察组表现更优秀(P<0.05);干预后,观察组的镇定催眠评分明显高于对照组(P<0.05);观察组不良反应发生率明显低于对照组(P<0.05)。结论 临床对TIAV治疗患者采用加速康复策略理念干预,以保障手术的成功、提高患者的精神及镇定警觉评分、降低其不良反应,有助于促进术后恢复。
