SENSOR: SonR®
World's only contractility sensor for automatic CRT optimization
SonR® CRT-D + SonRtip™ Atrial Lead
The Respond CRT system is a unique combination of a cardiac contractility sensor with an advanced optimization algorithm.
The SonR® sensor consists of a micro-accelerometer embedded in the tip of the SonRtip atrial lead.
SonR® measures the vibrations generated by the myocardium during cardiac contractions, which are correlated to LV dP/dt max.2,3,4
SonR® sensor continuously measures the contractility of the heart allowing for automatic optimization of AV and VV intervals. Optimization is performed on a weekly basis both at rest and during exercise.
This allows for cardiac resynchronization therapy to be continuously adapted to the individual needs of each patient.
SonR® optimization is as effective as echo-guided optimization.
The RESPOND-CRT trial successfully met its primary endpoint demonstrating that automatic AV & VV optimization with SonR® technology is safe and as effective as best practice AV and VV optimization using echocardiography.
75% of clinical responders in the SonR® group versus 70% in the control group (p<0.001) at 12 months.
SonRtip proven to be safe.
The rate of successful implantation of the SonRtip was 99.8% and the freedom from acute and chronic complications was 98.5% and 99.8%, respectively.
35% risk reduction in heart failure hospitalization.
The RESPOND-CRT landmark trial revealed that sensor-based CRT optimization with SonR® is associated with a 35% reduced risk in heart failure hospitalization.
