Right Ventricular and Left Atrial Strain Predict Volumetric Response to Cardiac Resynchronization Therapy.

ABSTRACT:

Background

While left-bundle-branch-block-related contraction patterns as well as echocardiography-derived strain are variably associated with the volumetric response to cardiac resynchronization therapy (CRT), the role of CMR-derived strain parameters is unexplored.

Methods

A total of 50 patients receiving CRT implantation were retrospectively analyzed, all of whom had undergone CMR imaging within one year before, and echocardiography within 6 months before and 6-12 months after CRT implantation. We assessed CMR-derived morphological and functional parameters with regard to the echocardiographic response, defined as a reduction in the left ventricular end-systolic volume of ≥15%.

Results

Among the standard CMR parameters, the indexed right ventricular volumes in end-
