Comparative Study to Examine Whether Echocardiography Performed During Cardiac Resynchronization Therapy Device Implantation Can Improve the Response Rate

NCT01014000 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Summary

Empirical implantation of the left ventricular lead is the prevailing practice in cardiac resynchronization therapy device implantation. The response rate to the therapy has been uniformly 70% only despite various methods to screen patients before device implantation. This study tested the hypothesis that echocardiography to assess acute resynchronization of the left ventricle during device implantation may improve the response rate to the therapy.
