Background: Because conventional echocardiographic parameters have several limitations, strain echocardiography has oftenbeen introduced in clinical practice. However, there are also obstacles in using it in clinical practice. Therefore, we wanted to findthe current status of awareness on using strain echocardiography in Korea. Methods: We conducted a nationwide survey to evaluate current use and awareness of strain echocardiography from the membersof the Korean Society of Echocardiography. Results: We gathered total 321 questionnaires from 25 cardiology centers in Korea. All participants were able to perform orinterpret echocardiographic examinations. All participating institutions performed strain echocardiography. Most of our studyparticipants (97%) were aware of speckle tracking echocardiography and 185 (58%) performed it for clinical and research purposes. Two-dimensional strain echocardiography was the most commonly used modality and left ventricle (LV) was the most commonlyused cardiac chamber (99%) for clinical purposes. Most of the participants (89%) did not think LV strain can replace LVejection fraction (LVEF) in their clinical practice. The common reasons for not performing routine use of strain echocardiographywas diversity of strain measurements and lack of normal reference value. Many participants had a favorable view of the future ofstrain echocardiography. Conclusion: Most of our study participants were aware of strain echocardiography, and all institutions performed strain echocardiographyfor clinical and research purposes. However, they did not think the LV strain values could replace LVEF. The diversityof strain measurements and lack of normal reference values were common reasons for not using strain echocardiography inclinical practice.
