Medtronic Gives Heart Docs Something to & #039;MARVEL & #039; At

Study results published this week in the Journal of the American College of Cardiology: Clinical Electrophysiology show that an investigational set of algorithms in Medtronic's Micra transcatheter pacing system (TPS) significantly improves synchrony and cardiac function in patients with impaired electrical conduction between the chambers of the heart, a condition called atrioventricular (AV) block. The results from the MARVEL 2 study are expected to be presented Nov. 16 at the American Heart Association's annual scientific sessions. Medtronic said that based on positive results from both its MARVEL and MARVEL 2 studies, the company has submitted a PMA supplement to expand the indicated population of the Micra pacemaker to patients with AV block and normal sinus rhythm. Touted as the world's smallest pacemaker, Micra was the first leadless pacemaker to win FDA approval in 2016. “While leadless pacing has many advantages compared to traditional pacemakers - including fewer infection-related complications - leadless pacemakers are currently only capable of single-chamber ventricular sensing and pacing,” said Larry Chinitz, MD, a co-principal investigator of the MARVEL 2 study, a cardiac electrophysiologist, and director of New York University's Langone’s Heart Rhythm Center. “Our investigation shows that accelerometer-based atrial-sensin...
