Newly Designed LVAD Helps Ailing Hearts Beat Better
 
A new implantable pulsatile left ventricular-assist device (LVAD) provides more physiologic assistance to patients suffering from severe heart failure.

The BestBeat system operates automatically in synchronous counterpulsation with the native left ventricle, thereby unloading the heart and optimizing tolerance to exercise and increased metabolic needs. The system allows variation of the left ventricular (LV) afterload, adapting the degree of assistance to the patient’s needs while synchronous counterpulsation and full-flow through the device are maintained. These characteristics make the system especially suitable as both a transplant bridge for chronic assistance and as a recovery bridge, since the counterpulsation allows the cardiac muscle to rest completely. The adjustable load allows the clinician to control the weaning phase, maintaining synchronous counterpulsation without decreasing blood flow.

The BestBeat system is being developed by NewCorTec (Rome, Italy) with technical assistance by et medical devices (Cavareno, Italy). The BestBeat system is an investigational device currently undergoing clinical trials in France and Germany.
