INTRODUCTION Conventional coronary artery bypass graftin(CCABG) with cardiopulmonary bypass (CPB) habeen accepted as an effective and safe treatment fomulti-vessel coronary heat disease. CPB may stilcontribute to the operation field because of threlatively easier technical requirement; but it alscauses a serious systematic inflammatory reactiowhich will lead to dysfunction of important organand higher cost for the patients. Off-pump coronarartery bypass grafting (OPCABG) has r… 相似文献

Objective： To evaluate the surgical clinical results of hypertrophic obstructive cardiomyopathy. Methods： We retrospectively collected data on 24 patients who underwent surgical management in the past ten years in two hospitals in China and Madras Medical Mission in India. Myomectomy was carried out on all patients. Among them 3 patients underwent mitral valve replacement; 2 patients underwent mitral valve repair （anterior mitral leaflet plication）; 2 patients underwent aortic valve replacement; 1 patient underwent aortic valve repair; 2 patients underwent aortic root replacement; 1 patient underwent Bentall＇s procedure and 1 patient underwent coronary artery bypass grafting because of a breached muscle bridge, Results： One patient died of post-operative heart failure. The mean follow-up time was 4.3 years, There was significant improvement in the symptomatic status. Sixteen patients were asymptomatic with good effort tolerance and only four patients had New York heart association （NYHA） Classes Ⅰ-Ⅱ due to associated valvular lesions, Conclusion： Our experience proved that symptomatic hypertrophic obstructive cardiomyopathy or non-symptomatic hypertrophic obstructive cardiomyopathy with combined heart disease is indication for surgery as surgical intervention could get better clinical results in this kind of patients compared with other non-surgical method because it beneficially reduces the systolic anterior motion （SAM） of the mitral valve leaflet, which could not be avoided by other non-surgical treatment. 相似文献

利用磁控溅射技术在玻璃基片上分别沉积ZnOx薄膜、TiO2-y薄膜和TiO2-y/ZnOx双层透明薄膜,改变薄膜沉积过程中的氩气(Ar)和氧气((O2)的比例,获得具有不同氧含量的ZnOx薄膜和TiO2-y薄膜.采用椭偏仪测定所有样品的折射率,仔细研究薄膜中氧含量对折射率的影响.分别选择具有较大的折射率TiO2-y薄膜和具有较小的折射率ZnOx薄膜的生长条件,制备TiO2-y/ZnOx双层薄膜,获得光密媒质/光疏媒质双层结构,并观察到He-Ne激光从ZnOx薄膜入射到TiO2-y/ZnOx界面上发生的全反射现象.研究成果适用于大学生物理实验中的研究型实验或大学创新实验. 相似文献

To evaluate the clinic outcome of off-pump coronary bypass grafting (OPCABG) of patients with coronary heart disease and chronic obstructive pulmonary disease, we collected and analyzed 1998-2002 data on 28 patients with these two diseases who had received off-pump coronary bypass operation in our hospital, and compared with data on those who also had the same two diseases but received on-pump coronary artery bypass at same time. There were no operation-related death;one died of respiratory failure 14 days after operation while staying in hospital; there were more respiratory complications in the conventional coronary artery bypass grafting group (CCABG) than in the OPCABG group; and the PaO2/FiO2 in the CCABG group was higher than that in the OPCABG group during operation because of CPB, but lower than that in the OPCABG group 6-12 hours after operation. OPCABG seemed more suitable than CCABG for coronary artery disease patients with chronic obstructive pulmonary disease due to less damage to their oxygen-exchange capability and the fewer respiratory complications. 相似文献
