Radial Strain Imaging-Guided Lead Placement for Improving Response to Cardiac Resynchronization Therapy in Patients With Ischemic Cardiomyopathy: A Randomized Clinical Trial

Status: Completed
Location: See all (9) locations...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable

The purpose of this study is to evaluate the use of radial strain imaging using speckle tracking analysis to predict the response to CRT in patients with ischemic cardiomyopathy (ICMP) with NYHA functional class 2-4 heart failure and a standard guideline-based CRT indication. Thus assessing the value of lead localization determined by radial strain imaging in a prospective, randomized manner.

Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: No

• Patients with ischemic CMP based on evidence of prior MI by history, coronary angiography/revascularization or imaging

• AHA ACC or ESC EHRA Guideline-based indication (Class I or II) for CRT and NYHA class II-IV heart failure
