Methods The data of 1 704 CABG cases were analyzed. 25 patients required LVAD after CABG (1. 5% ,25/1704). Results About 78% of 25 patients were weaned off LVAD, and 48% of them were discharged. IABP was used in 88% of patients. The major complications were MOF,lung disease,renal insufficiency/ failure, arrhythmia, coapulopathy, and infection. The causes of death were MOF, pump failure, renal failure, venticular fibrillation, respiratory failure, bleeding. Conclusion LVAD is a very useful tool in salvaging left ventricular failure. LVAD should be used as early as possible. Before weaning, trials should be madeat decreasing flow rates. 11 refs,2 tabs.展开更多

Methods From Sept. 2001 to May, 2002,90 cases underwent CABG. Among them, 40 cases with off-pump beating heart (OPCAB) and 50 with conventional coronary bypass grafting. All graft patency were verified intraoperatinlly with TTFM. The flow value of left internal mammary artery (LIMA) in 30 cases was also detected by the same way before grafting to left anterior descending (LAD). Results There was no operative death and severe complications. The mean flow value of LIMA in 30 cases was (42. 9 ± 33. 0) ml/min. The actual blood flow value, measured simultaneously by exsanguination was (37.4 ± 28. 8)ml/ min. Excel-lent correlation was demonstrated. The mean pulsatility index value (PI) was 1. 00 ± 0. 04. The flow curve showed both diastolic and systolic filling. The mean flow value of LIMA to LAD.saphenous vein graft (SVG) or radial artery (RA) to circumflex coronary artery (LCX)展开更多

Methods From June, 1999 to May,2000,45 children (30 male, 15 female) undergoing correction of cardiac defects were divided into three groups randomly: group Ⅰ no myocardial ischemia,group Ⅱ myocardial ischemia less than 60 minutes, group Ⅲmyocardial ischemia 】 60 minutes. There were no significant differences in the three groups in age, sex ratio, C/T ratio, or left ventricular function. Blood samples for analysis were collected before skin incision and at time intervals up to 6 days postoperatively. Analysis of creatine kinase MB.LDH and cardiac-specific troponin I was used for the detection of myocardial damage. Meantime, the ECG was checked for myocardial infarction. After the reperfusion, myocardial tissue was obtained from the free wall of right ventricle myocardial structure studies. Results The level of cTnI was increased展开更多

Methods Group 1 ( n = 25 ): mitral or/and arotic valve insufficiency, group 2 ( n = 17): valve stenosis and group 3 ( n = 14): simple congenital heart diseases. The load- independent index-end systolic elastance (Ees), pre-load recruited stroke work ( PRSW ), and the quantitive analyses of myocardial ultrastructure were observed and analyzed pre- and post-operatively. Results Ees was lower after operation than before operation in group 1, and it was a bit lower after operation in group 2. PRSW was significantly lower after operation than before operation in group 1, and it was similar before and after operation in group 2. The pre-load before operation and after-load after operation in group 1 increased. Vc%, Vvmyo% and Vvmit% were significantly lower in group 1 than in group 2.
