意大利开发出新型LVAD帮助病变心脏更好跳动

 
一种新型可植入搏动左心室辅助设备(LVAD)，能够为严重心脏衰竭患者提供更加符合生理状态的辅助。

这种BestBeat系统自动操作，与原来的左心室同步反搏，从而解除心脏负荷，提高心脏对运动以及代谢增加的耐受性。该系统允许左心室(LV)后负荷的变异，在同步反搏的同时适应患者不同程度的需求，并全流程维持设备。这些特点使得该系统特别适合于移植搭桥和恢复搭桥的长期辅助，因为反搏能够确保心肌彻底休息。可调节负荷能够帮助医生控制撤退期，维持同步反搏而不会降低血流量。

这种BestBeat系统是由NewCorTec(Rome, Italy)在et medical devices(Cavareno, Italy)提供技术支持下研制开发的。BestBeat系统正在法国和德国进行临床试验的研究性设备。

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.
