Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The ICONIC-M study is a multicenter randomized controlled study to assess patient response to CRT comparing ECGI map guided left ventricular lead placement with empirical lead placement.

The hypothesis of the investigation is to demonstrate that CRT LV lead implantation guided by a map obtained with the Amycard 01C System and showing LV Latest Electrical Activated Site (LEAS) in combination with a CT cardiac venogram improves CRT outcome. An improved CRT outcome is defined as a ≥30% increase in LVESVi reduction compared to empiric CRT LV lead implantation.

The sample size will be 136 in the Control arm and 194 in the Active arm. A total of 330 subjects.

The study follows an adaptive design, in where one interim analysis at 70% enrollment will be performed. The sponsor may stop enrollment when either one of the following conditions apply:

* Statistical significant difference between groups in the primary endpoint has been reached confirming a difference in reduction of the LVESVi of ≥30% in the Active arm compared to the Control arm
* There is no trend or reason to believe statistical significance will be reached with a higher sample size.

Statistical significance (primary endpoint) is reached at interim (70%) or at total (100%) of enrollment with a significance value P lower than 0.025.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study is conducted at European sites as a Post-Market Clinical Follow-Up study of a CE marked device (Amycard 01C). Its aim is to strengthen clinical evidence by assessing whether the use of this device for CRT planning improves clinical outcome in a statistically significant number of patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

The CRT device is implanted according to clinical practice, without pre-implantation planning. The outcome of the procedure is assessed via echography as per clinical practice.

In addition to clinical practice, the subjects are required to fill in a quality-of-life questionnaire and are subject to an ECG mapping procedure with the Amycard 01C device, including non-contrast CT, to assess the distance between left ventricular lead placement and the latest electrical activation site in the absence of planning information.

Intervention Type DEVICE

ECGi mapping using the CE marked Amycard 01C device and a non-contrast CT

Active

A pre-implantation ECG mapping with the Amycard 01C device, including CT, is performed prior to the CRT device implantation. The resulting target area for the left ventricular lead placement is communicated to the implanting physician, who will attempt to reach a point close to the target, using the available venous access. At six-month follow-up, response to the therapy is assessed using echocardiography, and a second ECG mapping with Amycard 01C is performed, to assess the distance between actual implantation site and target in the presence of pre-implantation planning information.
