A prosthetic valve comprising a stent frame, a valve structure, and a baffle structure. The stent frame defines a lumen. The valve structure is disposed within the lumen, and defines an inflow side and an outflow side. An outflow track is established within the lumen downstream of the outflow side and along which fluid flow from the valve structure progresses. The baffle structure is connected to the stent frame downstream of the outflow side and is configured to induce vortical flow, for example including a vortex ring. In some embodiments, the prosthetic valve is a transcatheter prosthetic mitral valve having three leaflets.
