Objective To compare the mid-term results of video-assisted pulmonary veins isolation and box-lesion for lone atrial fibrillation.Methods Between June 2010 to November 2012,80 lone atrial fibrillation(LAF) patients underwent minimally invasive surgical ablation in Beijing Anzhen Hospital,and all of them received left atrial appendage excision and Marshall ligament break in the surgery.Among them,37 cases were performed two epicardial ablation lines in order to created box-lesion based on PVI(14 paroxysmal AF and 23 persistent AF).Follow-up was finished after discharge.Results Mean follow-up was(18.8 ± 7.4) months,and 2 patients were died with non-cardiac disease.The success rate is 78.8％ (Paroxysmal AF 87.9％;Persistent AF 72.3％).In the paroxysmal AF patients,the success rate for PVI and Box lesion treatment was 84.6％ (11/13) and 92.9％ (13/14),P =0.45;in the persistent AF patients,the success rate for PVI and Box-lesion was 58.3％ (14/24) and 87.5％ (14/16),P =0.04.Conclusion Addition of epicedial ablation lines might increase the cure rate for lone AF therapy,especially for persistent AF.

Objective To conclude the preliminary results of aortic valve repair with autopericardium.Methods After routine median sternotomy the pericardium was isolated and immersed into the 0.6% glutaraldehyde immersion for 10 minutes, then rinsed off before use.Conventional extracorporeal circulation was established and diseased aortic valves were removed.The curves lengths between three commissures measured with the specific sizers.The corresponding size of the pericardial patchs was used to cut the new aortic leaflets.The continuous Johnson Prolene 4-0 sutures were used to fixed the new aortic valve leaflets to the anulus.Another new 4-0 prolene suture were used to fix the new three commissures outside the aortic wall with mat.The new mat stripes were used to fix the sinus in condition with the aortic sinus dilation or bileaflets malformation.Results Since 2015 October total 27 patients received aortic valve repair with autologous pericardium.The age was in the range of 27 to 60 years old including 18 female and 9 male.There were 7 cases diagnosed as aortic valve stenosis and 20 cases aortic insufficiency.And there were 3 cases bileaflets aortic valve deformity.The mean bypass time is(104±25)mins.Postoperative esophageal ultrasound showed good coaptation of the aortic valve without significant regurgitation.The mean transvalve gradient was(8.5±3.2)mmHg(1 mmHg=0.133 kPa).In the early stage one case diagnosed with aortic valve stenosis and regurgitation received monocusp repaired with autologous pericardial leave.But there was still moderate aortic regurgitation and had to receive the aortic valve replacement.All patients recovered well and were treated with Aspirin for 6 months.The followed up lasted for 3 to 13 months.Mean aortic occlusion time was(104±25) minutes.The patients were followed up for 3-13 months, the cardiac function and aortic valve function were stable, and no gradient increased.Conclusion It is relatively simple to perform the aortic valve repair with individual autologous pericardial sizer technique and the primary clinic results are satisfactory.It is worthy of further study and long-term follow-up.

Objective To investigate the clinical results of extracorporeal membrane oxygenation (ECMO) technique during the peri-operative heart transplantation. Methods The clinical data of heart transplantations supported by the ECMO were retrospectively analyzed, including during the bridge to transplant, working as routine bypass in the operation room, and supporting the heart failure after surgery. Results Three 3 cases were supported with ECMO to extend the waiting time: 2cases died of multi organ failure during the waiting, and the third one received the heart transplant and the ECMO was successfully removed. Totally 12 cases of heart transplantation received the modified open style ECMO techniques replacing the routine bypass. The ECMO was removed after assistance for (38 ± 14) h. All the recipients except one death recovered well without right ventricular failure or obvious tricuspid regurgitation which was common after heart transplantation. Ten cases received ECMO support for the heart failure after the transplant. The initial application time ranged from 2 h to 2 days and lasted 43～176 h. One died of infection and two died of multi organ failure nothing to do with ECMO application and other 7 discharged with NYHA Ⅰ/Ⅱ cardiac function. Conclusion Early use of ECMO could safely bridge the heart failure patients to the transplant. Replacing the routine with ECMO techniques in the heart transplantation could get good myocardial protection results even with long cold ischemic time and improve the cardiac function recovery. For the heart failure patients after the surgery the ECMO could afford good support effect.

Objective To establish a three- dimensional hindlimb gait data toolkit (THGT) for healthy and spinal cord injured (SCI) non-human primate (rhesus monkey) based on Matlab to realize upload of original data, automatic gait division, calculation and drawing of multiple gait parameters, etc. Methods Vicon system was used to collect three-dimensional hindlimb gait data of healthy and SCI (after 6 weeks) rhesus monkey to obtain the kinematics data of both hindlimbs in continuous strides. It was analyzed with THGT to process the gait division, calculation and drawing of multiple gait parameters. Results THGT read the data, distinguished cycles of gait, calculated 140 kinds of gait parameters and drew graphs of the results. Conclusion THGT extends the universality of the Vicon data, realizes automatically gait division and friendly interactive interface, and puts out the visible results.

Objective To summarize the clinical experiences in setting up cardiopulmonary bypass(CPB)using extracorporeal membrane oxygenation(ECMO)circuit and turning CPB to ECMO after open heart operations in 16 cases.Methods In the group of 16 cases,the annulations were via femoral vessels:by Medtronic ECMO machine and membrane oxygenator was used in all patients.All patients accepted A-V bypass.Results CPB was running smoothly during the operations,and converted to ECMO after the surgeries without complications,and the rate of ECMO withdraw was 93.75%.Mortality was 18.5%,and 81.25%of patients were discharged.Conclusion ECMO is an effective device for cardio and pulmonary support.Many patients with severe cardiac diseases and marginal cardiac function will need mechanical support after surgery.For these patients,setting up CPB using ECMO circuit during the operation and converting it to ECMO after surgery can prevent patients from additional exposure to a standard CPB circuitry.It helps decrease the inflammatory response,avoid dilution of patient's volume of cells and factors,and reduce expenses.

OBJECTIVETo present a method of quantitative diagnosis of craniofacial skeleton deformities based on three-dimensional computed tomography (3D CT).

METHODS20 cases with facial asymmetric deformities underwent 3D CT and the 3D images were reconstructed by Mimics 10.0 (Belgium). Anatomical landmarks were located and the coordinate of the landmarks obtained. Axial images of 1 patient with Romberg disease was used as representative case. The differences in the distance between the right landmarks and the left were calculated and analyzed.

RESULTSThe measurement results were not significantly different between two stages with an interval of 4 weeks ( P > 0.05), showing a reproducible resutls. The deviation of landmarks at facial midline increased gradually from upward to downward, reaching (2.63 +/- 0.54) mm at menton point. Paired landmarks showed asymmetry in three dimensions, especially gonion point on the left side, which was deviated 10.21 mm inward, 9.26 mm forward, 6.30 mm upward, compared to the opposite side.

CONCLUSIONSThe method of 3D CT quantitative analysis can provide precise information in the diagnosis and treatment planning of facial asymmetry deformity.
