A catheter including an elongate body, a first cutting head and a second cutting head both having a blade, where the blades moves relative each other to provide a shearing action for cardiac tissue. The catheter can further include a stent positioned over an inflatable balloon, where the inflatable balloon can deploy the expandable stent over sheared cardiac tissue. The catheter can further be included in a system having a sheath, where at least a part of the catheter resides in the lumen of the sheath. The sheath further includes a cardiac valve and an expandable filter. The sheath can move relative the cardiac valve and the expandable filter to deploy the cardiac valve and at least a portion of the expandable filter proximal the inflatable balloon and the expandable stent.
