The new technology of device therapy for chronic heart failure is mainly focused on two aspects, improving the electrical mechanical conduction and improving the mechanical structure of the heart. For improvement of electro-mechanical conduction, cardiac resynchronization therapy (CRT) has become the standard therapy for patients with moderate or severe chronic heart failure and ventricular conduction block. However nearly 30% of the CRT non-respond rate makes it the clinical hope to improve the curative effect. New technology mainly lies in increasing the respond rate, including multisite pacing, left ventricular endocardia pacing, wireless left ventricular endocardia pacing, and pulmonary impedance monitoring. In addition, contractility modulation cardiac (CCM) has more and more clinical application since it was first implanted in 2001. To improve the cardiac mechanical structure, the progress of valve repair and left ventricular assist device has been widely mentioned in recent years. New technology in the treatment of chronic heart failure has developed rapidly in recent years. Especially the application of new tools has made the operation more convenient and minimally invasive. With the progress of more and more clinical trials, it is believed that the application of new technologies will be more and more extensive, and the efficacy of heart failure treatment will be further improved.
