CRT-P or CRT-D in Dilated Cardiomyopathy

key information

study id #: NCT04139460

condition: Cardiomyopathy, Dilated, 3B

status: not yet recruiting

purpose:

The ICD-Reality study is a non-commercial, investigator-led, multicenter, prospective, randomized, controlled trial. We aim to determine the effect of CRT-D or CRT-P implantation in non-ischemic cardiomyopathy and heart failure patients.

The reason why we initiated this trial is the lack of evidence-based treatment for the significant number of these patients. In these patients, 5-year mortality remains as high as 20% despite recent therapeutic advances. Based on currently available evidence, because of a significant decrease in mortality due to modern pharmacotherapy, it is not certain which of these patients should receive a CRT-P and who should receive a CRT-D. No dedicated and adequately powered trial has addressed this important question.

We hypothesize that patients with symptomatic HF, LVEF =<35%, without left ventricular mid-wall fibrosis on LGE-CMR, will not benefit from CRT-D implantation compared with CRT-P only implantation.

If our hypothesis is confirmed, this could provide evidence for the management of these patients with a significant impact on common daily praxis and health care expenditures.

We aim to enroll 600 patients in the trial. 924 patients are needed to be screened for these 600 patients to be randomized.

Patients with non-ischemic HF visiting an out-patient department and possibly eligible for the trial will have their pharmacotherapy optimized.

Patients with a significant amount of fibrosis will be excluded from the study and treated according to local practice with an emphasis on ICD implantation to prevent SCD.

After fulfilling all eligibility criteria, including maximally tolerated pharmacotherapy, subjects will be randomized by the physicians who enrolled them in a 1:1 ratio to receive CRT-D or CRT-P implantation.

All patients will be followed-up for at least 3 years after the implantation.
