The Echo Seoul & Cardiac Imaging 2025 Symposium was held from Friday, September 19 to Sunday, September 21, 2025, at the Eun-Myeong Auditorium of Yonsei University Severance Hospital. Over the past 25 years, this symposium has established itself as an important academic forum for sharing the latest knowledge and clinical experience in the field of cardiac imaging, including echocardiography. This symposium was a great success, filled with meaningful moments made possible by the active engagement and support of all our attendees.

The symposium offered an in-depth exploration of the latest cardiovascular imaging techniques and their practical clinical applications, centered on a wide spectrum of cardiac conditions including cardiomyopathy, valvular heart disease, ischemic heart disease, myocarditis, congenital heart disease, and pulmonary hypertension. In particular, left ventricular diastolic function, which is a parameter of critical importance in understanding the symptoms and prognosis of heart disease, was systematically examined from its fundamentals through to the most current evidence. The "Diastology Stress Test Symposium" sparked lively discussion on the clinical potential and practical applications of diastolic function assessment.

The symposium was further distinguished by the participation of internationally renowned invited speakers — Otto A. Smiseth, Sherif Nagueh, and Bogdan Popescu — whose lectures provided attendees with direct access to cutting-edge global perspectives and a wealth of clinical expertise. Each session fostered vibrant discussions that transcended generational and experiential boundaries, allowing participants to explore practical and substantive answers to the real-world challenges encountered in clinical practice.

Echo Seoul & Cardiac Imaging 2025 came to a successful close, establishing itself as a significant venue for scholarly exchange where participants explored the present landscape and envisioned the future of cardiac imaging. We look forward to the continued growth of this symposium as a premier academic forum that contributes to the advancement of cardiovascular imaging and treatment, while providing practical support for both clinical and research fields.
