Localization of CRT According to Echocardiography: LOCATE-Pilot Study

Currently, the majority of heart failure patients who qualify for and receive a cardiac resynchronization therapy (CRT) device feel better than before their implant. However, there are some patients who do not improve after the implant. Michigan Heart is sponsoring a research study called LOCATE-Pilot to help understand whether the information from an echocardiogram, performed before implanting the CRT device, improves patients' responses to CRT. This is being done by evaluating your heart's function with an echocardiogram, to measure your heart's response during therapy. The study hypothesis is that response to CRT may be optimized by guiding left ventricular lead placement to the maximally delayed, viable basal segment of the left ventricle.
