What this trial studies

This study aims to evaluate the feasibility of a personalized approach to cardiac resynchronization therapy (CRT) implantation by utilizing a cloud-based roadmap that integrates 3D images from ECG activation sequences and coronary venous anatomy from cardiac CT scans. The roadmap will guide the placement of the left ventricular lead in areas of the heart that are electrically delayed. The hypothesis is that at least 75% of patients will experience a significant reduction in left ventricular end-systolic volume after the procedure, assessed at six months post-implantation.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with left bundle branch block and symptomatic heart failure who meet specific clinical guidelines for CRT.

Not a fit: Patients with a history of persistent atrial fibrillation or those who have previously undergone pacemaker or ICD implantation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved outcomes for patients with chronic heart failure by optimizing CRT lead placement.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in improving CRT outcomes through advanced imaging techniques.
