Can Global Longitudinal Strain Predict Response to Cardiac Resynchronization Therapy?

Cardiac resynchronization therapy (CRT) can be a powerful treatment for patients suffering with heart failure (HF) resulting in reversing the myopathic process, improving symptoms and extending survival. Although a clear requirement for CRT efficacy is a component of electrical delay, many unanswered questions remain regarding patient selection and CRT response. In this journal issue, an important article by Khidir et al. demonstrates the striking prognostic information that left ventricular (LV) global longitudinal strain (GLS) may provide for patients undergoing CRT.
