Valvular heart diseases are one of the major complications in the cardiovascular system. The failing native valve is routinely replaced by a prosthesis. However, these prostheses may often suffer from pathophysiological processes that can lead to structural and functional deterioration. In the scenario of Pervasive Healthcare, remote and non-invasive monitoring for the early diagnosis of implant-associated issues is extremely promising for improving the patient's quality of life. Thus, in this paper, a method to provide a metal-free aortic valve prosthesis with sensing and communication features without batteries is proposed. To preserve the mechanical and fluid-dynamic performances of the valve, an antenna and an RFID IC suitable for sensing are embedded into the structure. Numerical simulations and a preliminary experiment demonstrate that achieving a robust communication link with an external reader is feasible with only minimal structural changes to the valve.

Abstract
Valvular heart diseases are one of the major complications in the cardiovascular system. The failing native valve is routinely replaced by a prosthesis. However, these prostheses may often suffer from pathophysiological processes that can lead to structural and functional deterioration. In the scenario of Pervasive Healthcare, remote and non-invasive monitoring for the early diagnosis of implant-associated issues is extremely promising for improving the patient's quality of life. Thus, in this paper, a method to provide a metal-free aortic valve prosthesis with sensing and communication features without batteries is proposed. To preserve the mechanical and fluid-dynamic performances of the valve, an antenna and an RFID IC suitable for sensing are embedded into the structure. Numerical simulations and a preliminary experiment demonstrate that achieving a robust communication link with an external reader is feasible with only minimal structural changes to the valve.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
