World's only contractility sensor for automatic CRT optimization
SonRTM CRT-D + SonRtipTM 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.
SonRTM 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. Complications were very rare, with a 1% right atrial lead dislodgement rate.
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.
