Objective To evaluate the clinical application value of epicardial transesophageal echocardiography (ETE) in cardiac surgeries. Methods Using the transesophageal multi-plane ultrasonic probe of GE company, ETE were performed for a total of 53 patients undergoing cardiac surgeries with extracorporeal circulation and heart re-beat, evaluating valvular function, left ventricular systolic function and residual shunts. Results Qualiifed ETE images were obtained in all of the 53 cases without complications of infection, bleeding and serious arrhythmia. Intraoperative regional left ventricular systolic dysfunction happened in 5 cases and was promptly handled. Residual mitral regurgitation after valvular replacement was found in one case, which was reduced by valvuloplasty. One case showed moderate tricuspid regurgitation and another two cases indicated residual shunt. All the problems in the above cases were corrected in immediate surgeries. Moreover, the pressure gradient of one hypertrophic obstructive cardiomyopathic patient fell significantly to 8 mmHg after successful myectomy (the blood flow velocity fell from 3.2 m/s to 1.4 m/s). Conclusion Epicardial transesophageal echocardiogramphic examination is easy to handle and useful in monitoring abnormalities in cardiac surgery by providing hemodynamic and anatomic information.

BACKGROUND: Many scholars adopt allograft interbody fusion for vertebral body resection and reconstruction, bone fusion time is better than autologous bone graft's, and its integration provides an early support and stabilizing, but the preparation of allogeneic bone graft material is easy to destroy b0ne-inducing factor in matrix, which is not conducive to bone growth. OBJECTIVE: To innovatively design and verify the ability of reconstructing rabbit cervical vertebrae with the compound of humeral cortical ring allograft (HCA) packed with red bone marrow (RBM) and autogenous cancellous bone (ACB). DESIGN, TIME AND SETTING: Randomized controlled animal experiment was performed at the laboratory of Orthopedic Department in Renmin Hospital of Wuhan University, between October 2004 and March 2006. MATERIALS: Sixty healthy adult New Zealand white rabbits, of either sex, body mass of 2.0-2.5 kg, were involved in this study. Twelve rabbits were used for HCA preparation, while the remaining 48 rabbits were randomly divided into 3 groups with sixteen rats in each group. Autologous RBM was extracted from the anterior superior lilac spine through puncture; ACB was obtained from td-cortical bone of rabbit iliac crest. Autologous RBM and ACB were compounded and filled in the self-made HCA. METHODS: Models of the fourth cervical vertebrae defect were created by surgery to simulate tumor resection in New Zealand white rabbits, which were divided into 3 groups randomly. Combined transplant group was treated with the compound of RBM+ACB+HCA; autologous bone transplant group with autogenous lilac crest; HCA transplant group with HCA. MAIN OUTCOME MEASURES: Vertebral reconstructions were evaluated by X-ray, histopathological observation and scanning electron microscope, as well as measurement of serum alkaline phosphates at different periods postoperatively. RESULTS: Eight weeks post-surgery, graft materials fused with the upper and lower cervical fusion, a large number of bone callus were observed in combined transplant group and autologous bone transplant group; HCA transplant group was present with a small amount of callus growth and poor fusion. Serum alkaline phosphatase levels were elevated in all groups, significantly higher in combined transplant group and autologous bone transplant group compared with HCA transplant group (P < 0.01 ). There were no significant differences of serum alkaline phosphatase levels between combined transplant group and autologous bone transplant group at 4 weeks or among 3 groups 8 weeks (P > 0.05). Histological analysis exhibited numerous mature bone matrix, bone trabecula and bone marrow cavity formed in combined transplant group and autologous bone transplant group. Scanning electron microscopy showed that many new bone formations in combined transplant group and autologous bone transplant group.CONCLUSION: The compound of RBM+ACB+HCA and autogenous lilac crest transplantation can efficiently reconstruct cervical vertebrae, RBM+ACB can improve the reconstruction efficiency of HCA, and could use as a matedal in cervical reconstruction.

Objective To assess the accuracy of three-dimensional color Doppler echocardiography (3DCDE) for measuring left ventricular stroke volume (LVSV). Methods A total of 45 patients were studied to measure LVSV by 3DCDE and two-dimensional Doppler echocardiograph(2DDE). Full-volume three-dimensional echocardiography (3DE) was also performed to measure left ventricular end systolic (LVESV) ,end diastolic(LVEDV) ,and LVSV (LVEDV-LVESV), which served as a reference standard for comparison. Results Mean values of LVSV by 3DE,2DDE,3DCDE were (79. 3 ± 22. 6)ml, (74. 0 ± 20. 6) ml,(78. 7 ±22. 6)ml. respectively. Compared with LVSV by 3DE,the correlation was excellent for 3DCDE (r = 0.96), good for 2DDE ( r =0.89). Conclusions LVSV measurement by 3DCDE is reasonably accurate. This new technology may be a valuable clinical tool for assessing cardiac function.
