一種新型可植入搏動左心室輔助設備(LVAD)，能夠為嚴重心臟衰竭患者提供更加符合生理狀態的輔助。

這種BestBeat系統自動操作，與原來的左心室同步反搏，從而解除心臟負荷，提高心臟對運動以及代謝增加的耐受性。該系統允許左心室(LV)后負荷的變異，在同步反搏的同時適應患者不同程度的需求，并全流程維持設備。這些特點使得該系統特別適合于移植搭橋和恢復搭橋的長期輔助，因為反搏能夠確保心肌徹底休息。可調節負荷能夠幫助醫生控制撤退期，維持同步反搏而不會降低血流量。

這種BestBeat系統是由NewCorTec(Rome, Italy)在et medical devices(Cavareno, Italy)提供技術支持下研制開發的。BestBeat系統正在法國和德國進行臨床試驗的研究性設備。

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.
