In this episode I visit with Dr. John Gorcsan, an expert in echocardiography and strain imaging, to discuss the utility of ejection fraction. We discuss how EF came to be used in clinical practice, the importance of it in heart failure and the variation in measurement. We introduce strain imaging and what that adds to ejection fraction, particularly in the setting of severe mitral regurgitation.
