Cardiovascular Implants

Cardiovascular implants commonly involve both blood and soft tissue interactions with materials. The complications most commonly found with these implants, i.e., heart valve prostheses, vascular grafts, and cardiac devices, are listed in Table 8. Schoen and others have provided useful information on the perspectives, approaches, and techniques for evaluating cardiovascular implants.

TABLE 9 Implant Retrieval and Evaluation: Clinical Benefits

Provides prosthesis selection criteria Enhances patient—prosthesis matching Facilitates patient management Provides recognition of device complications

Reduces device complications by progressive prosthesis development Identifies subclinical patient-prosthesis interactions Elucidates patient—prosthesis interactions Determines tissue—material interaction mechanisms
