Objective:To investigate the predictive value of echocardiography hemodynamic parameters on 30-day survival rate after veno-arterial extracorporeal membrane oxygenation in refractory cardiogenic shock.Methods:A total of 44 patients with refractory cardiogenic shock who passed VA-ECMO weaning trial were retrospectively analyzed from September 2014 to February 2021. According to their 30-day survival outcomes after VA-ECMO removal, these patients were divided into the survival group (32 cases) and the death group (12 cases). Baseline data and the change rate of echocardiographic parameters between the first day of VA-ECMO and the day on VA-ECMO removal were compared, and the ultrasonic indicators affecting the survival of VA-ECMO within 30 days after withdrawal were determined.Results:The change rate of left ventricular ejection fraction(ΔLVEF%), the change rate of velocity time integral of the left ventricular outflow tract(ΔLVOT-VTI%), the change rate of ΔSa% and the change rate of right ventricular fractional area change(ΔRVFAC%) were improved significantly in the survival group ( P<0.05). The correlation coefficients between ΔLVEF% and ΔLVOT-VTI%, ΔLVEF% and ΔSa%, ΔLVEF % and ΔRVFAC% were 0.885, 0.861, 0.675, respectively( P<0.001); The correlation coefficient between ΔLVOT-VTI% and ΔSa was 0.918( P<0.001). ROC curve showed that the cut off values of ΔLVEF%, ΔLVOT-VTI%, ΔSa% and ΔRVFAC% to predict 30-day survival rate were 23.6%, 20.1%, 22.8% and 23.2% respectively, the sensitivity was 89.5%, 93%, 89.5% and 74.6% respectively, specificity was 66.7%, 66.7%, 66.8% and 75% respectively, the area under ROC curve (AUC) was 0.841, 0.867, 0.841 and 0.768, respectively. Conclusions:ΔLVEF%, ΔLVOT-VTI%, ΔSa% and ΔRVFAC% are predictive indicators of VA-ECMO withdrawl in patients with refractory cardiac shock. ΔLVOT-VTI% is the most valuable indicator of predicting 30-day survival rate after VA-ECMO withdrawl. Patients who meet two or more VA-ECMO echocardiographic indicators are more likely to succeed in VA-ECMO withdrawl. The improvement of right ventricular systolic function is a prerequisite for survival after 30 days of VA-ECMO withdrawal, while LVEF is an important criterion for survival after 30 days of VA-ECMO withdrawal.

Methods:A total of 10 subjects underwent three-dimensional transesophageal echocardiography (3D-TEE) and proved to be without mitral diseases were collected as mitral normal group from February 2017 to December 2018 in Renmin Hospital of Wuhan University, 10 mitral stenosis patients were collected as mitral stenosis group, and 10 mitral regurgitation patients were collected as mitral regurgitation group. Hemodynamic parameters of velocity (peak E), pressure gradient were obtained by two-dimensional transthoracic echocardiography in three groups, and the degree of mitral valve stenosis and regurgitation were also evaluated. Then 3D-TEE was performed to obtain the 3D volume image of mitral valve. After image post-processing and 3D modeling, the valve mold was printed with soluble material polyvinyl alcohol (PVA). The mixture of human skin silicone, silicone oil, starch and curing agent were poured into the mitral valve mold in a certain proportion to make flexible silicone mitral valve model. Then, the compliant valve model was placed in mock circulatory system (MCS), regularly opening and closing as it in vivo in the heart cycle. The hemodynamic parameters of mitral valve were measured again in vitro and the degree of stenosis and regurgitation was also evaluated respectively. Paired t test was used for statistical analysis of in vivo and in vitro measurements in two groups, and the consistency test was performed. Results:The mitral valve 3D-TEE images of all patients were successfully post-processed, mitral valve molds were printed and flexible models were made. In vitro hemodynamic tests were all completed. The opening and closing state of the valve model in vitro was similar to that in vivo. Mitral valve regurgitation was detected in mitral regurgitation group in vitro, with degree to that in vivo. There were no statistically significant differences in hemodynamic parameters measured in vivo and in vitro models (all P>0.05), with a high consistency ( r=0.76). Among the 10 patients with mitral stenosis and 10 patients with mitral regurgitation, 18 patients were evaluated as same degree as in vivo. Conclusions:3D printing of compliant mitral valve model based on ultrasound image is feasible, which reproduced hemodynamic features of mitral valve in vitro, setting foundation for further surgery simulation and clinical decision-making.
