NCT03125720

Brief Summary

CRT response will be significantly better using image fusion of SPECT MPI and fluoroscopy venogram to guide LV lead placement at the latest activation segment without scar than standard-of-care implantation.

Outcome Measures

Primary Outcomes (1)

  • Changes in LVESV

    Changes in LVESV between baseline and 6-month follow-up (a continuous variable): LVESV will be assessed by echocardiography (Simpson's rule). Changes in LVESV will be compared between the two groups.

    6-month follow-up

Secondary Outcomes (4)

  • CRT response rate

    6-month follow-up

  • Changes in LVEF

    6-month follow-up

  • Composite clinical response rate

    6-month follow-up

  • All-cause mortality and composite clinical endpoints

    6-month follow-up

Study Arms (2)

GUIDED group

EXPERIMENTAL

Image fusion of SPECT MPI and fluoroscopy venography to guide LV lead placement for improved CRT response in the guided group.

Other: Image fusion of SPECT MPI and fluoroscopy venography

Control group

NO INTERVENTION

No Image fusion of SPECT MPI and fluoroscopy venography to guide LV lead placement for improved CRT response.

Interventions

In this study, MPI-Fluoro Fusion tool is used to help the implanting physicians to precisely implant LV lead to the optimal/suboptimal venous segments in the guided group.
