Objective To evaluate the application valve of intraoperative device closure secundum atrial sepetal defect (ASD) associated with deficient rims inducted by transoesophageal echocardiography (TEE). Methods Twenty-three patients with ASD were diagnosed by transthoracic echocardiography (TTE) ,and underwent an attempted intraoperative device closure through a right antierior minithoraetomy. The positon, type and size and rim of ASD were defined by TEE in preoperation, the placement of the device inducted and evaluated by TEE intraoperation,and followed by TTE after one week. Results Twenty-three patients with ASD were closed excellently. There were not shunt of atrial level in 20 patients, trivial shunt in 3 patients. However,follow-up after one week TTE indicated that all patients had no shunt,and the diameter of right atrium and right ventricle was decrease significantly (P <0.05), and pulmonary artery pressure was less than before (P <0.05). Conclusions It is very important that TEE induct the closure of ASD associated with deficient rims in micro-operative room.

Objective To investigate left ventricular rotation in heahhy subj ects and patients with hypertrophy cardiomyopathy(HCM). Methods Twenty-five healthy subjects and 41 patients with HCM were enrolled. Two-dimensional standard echocardiography were performed and analyzed using Siemens Sequoia C512 system and velocity vector imaging 2.0 version. Left ventricular end diastollc volume(EDV).end systolic volume(ESV),left ventricular ejection fraction(LVEF),systolic peak rotation velockv and displacement of endocardium and epicardium of basal and apical part of left ventricle were measured.Difference of basal and apical rotation velocity and displacement between endoeardium and eDicardium(DVbase,DVape,DDbase,DDape) were calculated. Results Left ventricle rotated clockwise at basal part and counterclockwise at apex during systole. It rotated stronger at apex(P<0.05 or P<0.001)than at basal part and stronger in endocardium than in epicardium(P<0.01 or P<0.001). The rotation velocitv time curve consisted of a peak during systole and two peak during diastole,while the rotation displacementtime curve was composed of a smaller diastolic peak and a larger systolic peak. There was asvmmetricalhypertrophy at the basal part of HCM patients,and DVbase and DDbase were significantly increased(P<0.01 or P<0.001) in the significant hypertrophy segment. Conclusions Velocity vector imaging can assess left ventricular rotation effectively. HCM patients acquire mismatch of endocardium and epicardiuIn rotation.

Objective:To evaluate the influence of transcatheter aortic valve replacement (TAVR) on left atrial strain by two-dimensional speckle tracking echocardiography.Methods:Thirty-five patients, who were admitted for TAVR in Zhongshan Hospital of Fudan University from September 2015 to July 2018, were recruited. Echocardiography was performed 1 day before and 12 months after TAVR. Traditional ultrasound results, including aortic valve area (AVA), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), left atrial volume index (LAVI), peak velocity of tricuspid regurgitation (Vtr), peak velocity of the lateral wall of mitral annulus in early diastolic period (e′) and the ratios of peak mitral orifice velocity in early diastolic period to e′ (E/e′), were recorded. Two-dimensional speckle tracking imaging derived left atrial strain, which included reservoir (LASr), conduction (LAScd) and contraction (LASct), were recorded as well. The differences between pre-operation and post-operation were analyzed.Results:Compared to pre-operation, aortic valve area was increased ( P<0.001). Left ventricular systolic function was improved significantly (LVEDV and LVESV were decreased, LVEF was increased, all P<0.001). As to the left ventricular diastolic function, although LAVI and Vtr were decreased (both P<0.05), e′ and E/e′ were hardly changed (both P>0.05). Meanwhile, left atrial strain, including LASr, LAScd and LASct, were improved significantly 1 year post-TAVR (all P<0.01). Conclusions:Left atrial strain is able to evaluate the left atrial function of reservoir, conduction and contraction.Left atrial strain can be a promising tool of assessing left atrial function in patients underwent TAVR.
