Objective To evaluate the accuracy of preoperative diagnosis on the anatomy of coronary artery of patients with arterial switch operation(ASO) using echocardiography, to conclude the diagnostic methods. Methods From March 2007 to March 2008,50 patients were performed ASO after the diagnosis with eehoeardiography. Prior to the operation, evaluation was conducted to all of anatomical pattern of the coronary artery,and the comparison was made to the observation in the operation. There were 23 patients with complete transposition of great artery(TGA), 20 patients with double outlet of right ventricle of abnormal great artery(DORV), 2 patients with corrected transposition of the great arteries(CTGA), 1 patients with double outlet of left ventricle of abnormal great artery (DOLV), 2 patients with TGA complicated with total anomalous pulmonary venous connection (TGA + TAPVC), 2 patients with TGA complicated with pulmonary valve stenosis(TGA + PS). Results Among 50 patents,there were 40 patients with normal coronary artery,and 10 patients with abnormal coronary arteries. Except for 2 patients failing to being successfully diagnosed due to bad condition of image,48 patients could be revealed the origin and the direction of the major coronary arteries, the visibility proportion was 96.0%. Compared to the observation in the operation,the total echocardiography accuracy for 48 patients was 95.8%. Among the 40 patients with normal coronary arteries,39 patients were diagnosed accurately except 1 patient failed to be showed clearly by echo. In the 10 patients with abnormal coronary arteries,4 patients with single abnormal coronary artery, 2 patients with 2 coronary artery originating from the same coronary sinus, 2 patients with left anterior descending coronary artery originating from right coronary artery, 2 patients with 2 coronary artery originating from two adjacent coronary sinus. One patient failed to be diagnosed by echo for the bad image,2 patients was misdiagnosed by echo, the accuracy of echo was 77.8%. Conclusions Through multi-section scanning,echocardiography can accurately diagnose anatomical pattern of coronary artery for most of ASO,thus providing comprehensive and accurate diagnosis information for ASO.

Objective To investigate the efficacy of normative ankle balance training on chronic ankle instability (CAI).Methods Ninety patients were randomized into control group (17 males,28 females;13-26 years,mean 19.6 years) and experiment group (18 males,27 females;14-27 years,mean 20.3 years) according to the random number table.There were 19 left ankles and 26 right ankles injured in control group,and 19 left ankles and 26 right ankles injured in experiment group.Patients in control group only completed routine muscle strength training.Besides the routine muscle strength training,balance training (rubber band,spongy cushion,balance pedal,rubber balance ball and jump ball) were added in experiment group.The two groups were compared with respect to foot and ankle disability index (FADI),anterior,posterior-median and 45° to posterolateral direction reach distance of star excursion balance test (SEBT) and visual analogue score (VAS).Results After training,comparison of experiment and control groups showed significant differences in FADI (35.16 ± 3.23 and 22.33 ± 1.36),SEBT distance in posterior median direction [(78.59 ± 7.22) ％ and (71.89 ±7.11)％],SEBT distance in 45° to posterolateral direction [(75.79 ± 8.27)％ and (68.95 ±8.03) ％] and VAS [(3.01 ± 0.91) scores and (3.42 ± 1.02) scores] (P ＜ 0.05).For intragroup comparison,FADI,SEBT and VAS in experimental group showed significant differences before and after training (P ＜ 0.05),but only FADI in control group differed significantly before and after training (P ＜0.05).Conclusion Normative balance training can improve CAI patients' self-feelings of dynamic balance and instability with satisfactory therapeutic efficacy,and is worthy to be popularized.

Objective To explore the value of echocardiography on diagnosis and differential diagnosis of aortico-left ventricular tunnel(AOLVT).Methods Echocardiographic features of 9 patients with AOLVT were reviewed and analyzed.The diagnosis methodology was summarized;the reasons for missed diagnosis and misdiagnosis by echocardiography were analyzed.Results Among 9 patients with AOLVT,one was diagnosed through CT examination prior to the operation and died from the cardiac arrest.The others all received the surgical operation and were diagnosed as AOLVT.Five patients were accurately diagnosed by echocardiography prior to the operation,4 patients were misdiagnosed,in which 3 patients were diagnosed as aortic valve regurgitation,one patient was diagnosed as aortic dissecting aneurysm.The diameter of left ventricle(LV)decreased and LV ejection fraction increased distinctively for 7 operated patients(P＜0.001)in six months after operation.Only one operated patient failed to recover from the LV dysfunction and died of aortic valve perivalvular leak in two monthes.Conclusions The diagnosis of the AOLVT mainly depends on the echocardiography.By enhancing the understanding on such disease and investigating on the structure and hemodynamics will be contributive to the accurate diagnosis of echocardiography.
