Experimental Validation of a Cardiac Simulator for in vitro Evaluation of Prosthetic Heart Valves

OBJECTIVE This work describes the experimental validation of a cardiac simulator for three heart rates (60, 80 and 100 beats per minute), under physiological conditions, as a suitable environment for prosthetic heart valves testing in the mitral or aortic position. METHODS In the experiment, an aortic bileaflet mechanical valve and a mitral bioprosthesis were employed in the left ventricular ...

Anticoagulation for Mechanical Heart Valves

Although mechanical heart valves (MHV) are more durable than tissue valves, they are more thrombogenic. Consequently, patients with MHV require long-term anticoagulation with vitamin K antagonists, such as warfarin. Although effective, warfarin has well-known limitations, including multiple drug and food interactions, and the challenges of coagulation monitoring and maintaining the internationa...

Automatic Test Bench Generation

In current design practice synthesis tools play a key role, letting designers to concentrate on the specification of the system being designed by carrying out repetitive tasks such as architecture synthesis and technology mapping. However, in the new design flow, validation still remains a challenge: while new technologies based on formal verification are only marginally accepted for large desi...

Preface: Heart valves.

Reference to this organ, which perhaps was not commonplace in the scientific literature 15 years ago, has become exceedingly prevalent in the past 5 years. The field of heart valve research has become contemporary due to a heightened awareness of the seriousness and frequency of heart valve disease. Indeed, valve therapies are still extremely limited for patients above the age of 75 or less tha...
