摘要

Permanently implantable hemodynamic monitors show great promise in providing personalized and cost-efficient care to heart failure patients by providing timely intracardiac pressure data under ambulatory conditions. The data may be used to titrate maintenance therapies and to monitor health status so that more intensive interventions can be planned and performed under optimal conditions. In this pilot study, we present the results of the implantation of a novel wireless, battery-less pressure sensor into the apex of the left ventricle of four dogs for a period of 8 weeks. All animals recovered to a normal state and did not show any clinical signs of cardiac insufficiency or any complications suggestive of thromboembolism. All sensors functioned throughout the implantation period and provided detailed waveforms of ventricular pressure. ASAIO Journal 2012; 58:83-87.
