This video illustrates how the Micra AV leadless pacemaker is delivered via catheter and enables atrioventricular (AV) synchrony. The device was cleared by the U.S. Food and Drug Administration (FDA) in January 2020, expanding the number of potential candidates who can receive leadless, catheter delivered pacemakers in the U.S.
The device is the world’s smallest pacemaker with atrioventricular (AV) synchrony. It is indicated for the treatment of patients with AV block, a condition in which the electrical signals between the chambers of the heart (the atria and the ventricle) are impaired. It is similar to the single chamber Micra TPS pacemaker that has been on the market since 2016. However, the Micra AV has several additional internal atrial sensing algorithms which detect cardiac movement, allowing the device to adjust pacing in the ventricle to coordinate with the atrium, providing “AV synchronous” pacing therapy to patients with AV block. The device senses when blood is flowing through the right ventricle.
