A heart valve stent (25) and method for treating a patient with a fluid circulatory system defect is provided. The stent has a metal stent body (14), which is expandable from a compressed state to an expanded state. The stent body in the expanded state has a hollow structure and a leaflet (10) attached thereto with the leaflet movable from an open to a closed position to allow unidirectional fluid circulation and to prevent non-unidirectional fluid circulation through the hollow structure, which is translucent to magnetic resonance imaging signals by not producing eddy currents in response thereto. |
