To obtain the true status of quality control for transthoracic echocardiography image archiving and reports in medical institutions of all levels in various regions of China, in order to provide guidance for quality control work.

The "Cardiac Ultrasound Quality Control Working Group" conducted a nationwide survey questionnaire on the quality control of transthoracic echocardiography image archiving and reports.

The two-dimensional views with an image archiving rate of over 80% in conventional transthoracic echocardiography included apical four chamber view (A4C; 98.97%), parasternal long-axis view of the left ventricle (PLAX-LV; 98.65%), parasternal short-axis view of the aortic valve (PSAX-AV; 96.66%), parasternal long-axis view of the pulmonary artery (PLAX-PA; 87.96%), apical five chamber view (A5C; 87.19%), and parasternal short-axis view of the mitral valve (PSAX-MV; 83.63%). The Doppler sections with an image archiving rate of over 80% included the flow and spectrum of A4C-MV (94.45%), A4C-TR (92.55%), A5C-AV (89.50%), A4C-MR (87.77%), PV (86.26%), A5C-AR (85.36%), PSAX-AV (85.07%), and PLAX-LV (83.63%), which can meet the basic requirements for displaying the structure of heart cavities and evaluating the hemodynamics of each valve. The image archiving rates of tissue Doppler imaging for the septal wall of the mitral annulus, the lateral wall of the mitral annulus, and the right ventricular free wall of the tricuspid annulus were 84.40%, 64.75%, and 25.91%, respectively, reflecting that some ultrasound physicians did not pay enough attention to the evaluation of left and right ventricular systolic function. The most common suggestions for image archiving and reporting of transthoracic echocardiography were the lack of standards for image archiving and reporting of transthoracic echocardiography for different cardiovascular diseases, as well as the need for standardized training.

This large scale research provides an important basis for the implementation of quality control work. The "Cardiac Ultrasound Quality Control Working Group" will carry out work from multiple aspects such as hardware equipment development, clinical training, cardiac single disease ultrasound quality control, and structured report templates simultaneously.
