Background and Objectives: We assessed the ability of portable echocardiography (with contrasts) to clearly delineate the cardiacstructure, and evaluated the impact of its use on the diagnosis and management of critically ill patients in Korea. Subjects and Methods: We prospectively enrolled 123 patients (mean age 66±16 years), who underwent portable transthoracicechocardiography (with contrast) for image enhancement at 12 medical centers. The quality of the global left ventricular (LV) images, thenumber of the regional LV segments visualized, the ability to visualize the LV apex and the right ventricle (RV), and any changes in thediagnostic procedure and treatment strategy were compared before and after the contrast. Results: Of the 123 patients, 52 (42%) were using mechanical ventilators. The amount of poor or uninterpretable images decreased from48% to 5% (p<0.001), after the contrast. Before the contrast, 15.6±1.1 of 16 LV segments were seen, which improved to 15.9±0.6segments (p=0.001) after the contrast. The ability to visualize the LV apex increased from 47% to 94% (p<0.001), while the inability toclearly visualize the RV decreased from 46% to 19% (p<0.001). Changes in the diagnostic procedure (for example, not requiring othertypes of imaging studies) were observed in 18% of the patients, and the treatment plan (medication) was altered in 26% of patients afterthe contrast echocardiography. Conclusion: The use of a contrast agent during the portable echocardiography, in intensive care settings, can improve the image qualityand impact the diagnostic procedures and treatment for Korean patients.
