Sorin Introduces SonR CRT Optimisation System Equipped with Hemodynamic Sensor

Medical company Sorin has announced that it has acquired the CE approval and is ready to launch the SonR Cardiac Resynchronisation Therapy (CRT) optimisation system, which uses the SonR hemodynamic sensor. This sensor has been incorporated in the Paradym RF SonR CRT-D device and the SonRtip atrial pacing lead.

CRT is a method of treatment for heart failure patients under which timed electrical pulses are sent to the heart chambers in order to help the heart function in a normal manner. However past studies have shown that conventional clinic-based echocardiography is not effective in most heart failure patients. CRT through other devices also involves time consuming processes and do not show effective results. It is important to customise the therapy according to the needs of each patient so that the times at which the electric impulses are sent are programmed correctly. All the current CRT procedures which are used to determine the timings of electric pulses are manual and can be done only once on the patient and particularly when the patient is taking rest.

The CRT optimisation system’s SonR sensor which has been developed through 10 years of clinical research measures the vibrations of the heart muscle during the daily activities of the patient. This data is then transmitted to the CRT-D device and based on the data the system adjusts automatically every week to provide the ideal time setting for the patient. The sensor’s measurements are equivalent to the LVdP/dtmax which is the standard for tracking contractility of the left ventricle. This concurrence means that the system is reliable and can provide CRT settings while the patient is resting or performing an activity.
