Multicenter InSync Randomized Clinical Evaluation - MIRACLE (Pacing Study)


The goal of the MIRACLE trial was to compare the effect of cardiac resynchronization therapy (CRT) versus no CRT on the quality of life and functional capacity in patients with chronic heart failure (CHF) and ventricular dysynchrony, as well as to assess the safety of CRT using the Medtronic InSync® System in patients with CHF.
