1. Apparatus for resecting a diseased heart valve of a heart, the apparatus comprising: an elongate member to allow the apparatus to be positioned in the heart, the elongate member having a distal end;a selectively expandable portion having a proximal end and a distal end, wherein the selectively expandable portion is positioned at the distal end of the elongate member, the selectively expandable portion defines a longitudinal axis from the proximal end to the distal end and is selectively expandable from a first position having a given width in a perpendicular direction to the longitudinal axis to a second position having a larger width in the perpendicular direction to the longitudinal axis; andat least one cutting element, for cutting the diseased heart valve, disposed on the elongate member wherein the at least one cutting element is moved from the first position to the second position by the selectively expandable portion;wherein the selectively expandable portion has a first opening extending into the proximal end, and the selectively expandable portion having a given width from the first opening to an outer surface in a direction perpendicular to the longitudinal axis of the selectively expandable portion, the given width configured to prevent a wall of a cardiovascular structure from being cut by the cutting element disposed on the elongate member that is within the first opening and to permit the apparatus to be placed within the diseased valve,wherein the selectively expandable portion comprises at least three expandable arms and the at least one cutting element is disposed on at least one of the at least three expandable arms,wherein at least one of the at least three expandable arms having the cutting element disposed thereon defines a window recess therein having a given depth from an outer surface, andfurther wherein the cutting element is disposed in the window recess. 2. Apparatus according to claim 1 wherein the at least one cutting element is disposed on the selectively expandable portion of the apparatus. 3. Apparatus according to claim 2 wherein when the selectively expandable portion is in the second position, the at least one cutting element cuts as the selectively expandable portion is rotated with respect to the longitudinal axis of the selectively expandable portion. 4. Apparatus according to claim 2 wherein the at least one cutting element extends longitudinally along the longitudinal axis of the selectively expandable portion such that when the at least one cutting element is in the second position, the at least one cutting element cuts as the selectively expandable portion is rotated with respect to the longitudinal axis of the selectively expandable portion. 5. Apparatus according to claim 2 wherein the at least one cutting element comprises a plurality of blades that move together and in a similar manner from the first position to the second position. 6. Apparatus according to claim 5 wherein the selectively expandable portion further comprises a hinge mechanism holding the blades together, the apparatus further comprises a control rod extending from the proximal end of the selectively expandable portion, and the control rod is able to position the blades from the first position to the second position. 7. Apparatus according to claim 1 wherein the at least one cutting element extends longitudinally along the elongate member and when the selectively expandable portion is in the second position, the at least one cutting element cuts as the selectively expandable portion is rotated with respect to the longitudinal axis of the selectively expandable portion. 8. Apparatus according to claim 1 further comprising a first restraining element at the proximal end of the set of expandable arms and a second restraining element at the distal end of the set of expandable arms, wherein the first and second restraining elements selectively position the set of expandable arms between the first and second positions. 9. Apparatus according to claim 1 wherein the elongate member comprises a catheter and the first position is with the selectively expandable portion being inside the distal end of the catheter and the second position is with the selectively expandable portion being outside the distal end of the catheter. 10. Apparatus of claim 1 wherein the cutting element comprises a wire. 11. Apparatus of claim 10 wherein the wire comprises an electrocautery element. 12. Apparatus of claim 10 wherein the wire is rotary driven. 13. Apparatus of claim 10 wherein the wire is reciprocally driven. 14. Apparatus of claim 10 wherein the wire comprises a rough surface. 15. Apparatus for resecting a diseased heart valve of a heart, the apparatus comprising: an elongate member to allow the apparatus to be positioned in the heart, the elongate member having a longitudinal axis and a distal end;a selectively expandable portion having a proximal end and a distal end, wherein the selectively expandable portion is positioned at the distal end of the elongate member, the selectively expandable portion defines a longitudinal axis from the proximal end to the distal end and is selectively expandable from a first position having a given width in a perpendicular direction to the longitudinal axis to a second position having a larger width in the perpendicular direction to the longitudinal axis; andat least one cutting element, for cutting the diseased heart valve, disposed on the elongate member within the selectively expandable portion, wherein the at least one cutting element is moved from the first position to the second position by the selectively expandable portion, andwherein the selectively expandable portion comprises at least three expandable arms and the at least one cutting element is disposed on at least one of the at least three expandable arms,wherein at least one of the at least three expandable arms having the cutting element disposed thereon defines a window recess therein having a given depth from an outer surface, andfurther wherein the cutting element is disposed in the window recess. 16. Apparatus for resecting a diseased heart valve of a heart, the apparatus comprising: an elongate member to allow the apparatus to be positioned in the heart, the elongate member having a distal end;a selectively expandable portion having a proximal end and a distal end, wherein the selectively expandable portion is positioned at the distal end of the elongate member, the selectively expandable portion defines a longitudinal axis from the proximal end to the distal end and is selectively expandable from a first position having a given width in a perpendicular direction to the longitudinal axis to a second position having a larger width in the perpendicular direction to the longitudinal axis; andat least one cutting element, for cutting the diseased heart valve, disposed on the elongate member wherein the at least one cutting element is moved from the first position to the second position by the selectively expandable portion;wherein the selectively expandable portion comprises at least three expandable arms and the at least one cutting element is disposed on at least one of the at least three expandable arms,wherein at least one of the at least three expandable arms having the cutting element disposed thereon defines a window recess therein having a given depth from an outer surface, andfurther wherein the cutting element is disposed in the window recess, andwherein the elongate member comprises a catheter and the first position is with the selectively expandable portion being inside the distal end of the catheter and the second position is with the selectively expandable portion being outside the distal end of the catheter.
