What this trial studies

The ICONIC-M study is a multicenter randomized controlled trial designed to evaluate the effectiveness of cardiac resynchronization therapy (CRT) guided by advanced non-invasive cardiac mapping compared to traditional lead placement methods. The study utilizes the Amycard 01C System to identify the optimal left ventricular lead placement based on the latest electrical activation site. By comparing outcomes in a total of 330 participants, the study aims to demonstrate a significant improvement in heart function as measured by left ventricular end-systolic volume index (LVESVi). An interim analysis will be conducted to assess the efficacy of the intervention during the trial.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with heart failure who are in sinus rhythm and are suitable for CRT device implantation.

Not a fit: Patients with previous cardiac device implants or those with contraindications to CT scanning or body surface ECG mapping may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved heart function and quality of life for patients with heart failure.

How similar studies have performed: Previous studies have shown promising results with similar mapping techniques, suggesting potential for success in this novel approach.
