Abstract

A prosthetic heart valve includes a stent and a valve assembly attached to the stent. The stent has a longitudinal axis, a distal end and a proximal end adapted to reside adjacent the aortic annulus of a patient. The proximal end of the stent is oriented at an oblique angle to the longitudinal axis.

Claims

1. A prosthetic heart valve, comprising:

a stent having a collapsed condition and an expanded condition, a proximal end adapted to reside adjacent the aortic annulus in a patient, a distal end, a first side having a first length between the proximal end and the distal end, and a second side having a second length between the proximal end and the distal end, the second length being less than the first length; and

a valve assembly attached to the stent.

2. A prosthetic heart valve, comprising:

a stent having a collapsed condition and an expanded condition, a longitudinal axis, a distal end, and a proximal end adapted to reside adjacent the aortic annulus in a patient, the proximal end being oriented at a first oblique angle to the longitudinal axis; and

a valve assembly attached to the stent.

3. The prosthetic heart valve of claim 2, wherein the stent has a first side having a first length between the proximal end and the distal end, and a second side having a second length between the proximal end and the distal end, the second length being less than the first length.

4. The prosthetic heart valve of claim 2, wherein the valve assembly is attached to the stent at a second oblique angle to the longitudinal axis.

5. The prosthetic heart valve of claim 4, wherein the second oblique angle is between about 5°

and about 25°

.

6. The prosthetic heart valve of claim 5, wherein the second oblique angle is about 15°

.

7. The prosthetic heart valve of claim 4, wherein the first oblique angle is substantially equal to the second oblique angle.

8. The prosthetic heart valve of claim 2, wherein the distal end of the stent is oriented substantially orthogonally to the longitudinal axis.

9. The prosthetic heart valve of claim 2, wherein the first oblique angle is between about 5°

and about 25°

.

10. The prosthetic heart valve of claim 9, wherein the first oblique angle is about 15°

.

11. The prosthetic heart valve of claim 2, wherein the distal end of the stent is oriented at a second oblique angle to the longitudinal axis.

12. The prosthetic heart valve of claim 11, wherein the second oblique angle is between about 5°

and about 25°

.

13. The prosthetic heart valve of claim 12, wherein the second oblique angle is about 15°

.

15. The prosthetic heart valve of claim 11, wherein the valve assembly is attached to the stent at a third oblique angle to the longitudinal axis.

16. The prosthetic heart valve of claim 15, wherein the first oblique angle, the second oblique angle and the third oblique angle are substantially equal.

14. The prosthetic heart valve 11, wherein the second oblique angle is about equal to the first oblique angle.

17. A method of replacing a native heart valve of a patient, the native heart valve having a valve annulus and native valve leaflets, the method comprising:

providing a prosthetic heart valve including a stent and a valve assembly attached to the stent, the stent having a collapsed condition and an expanded condition, a longitudinal axis, a distal end, and a proximal end oriented at a first oblique angle to the longitudinal axis; and

implanting the prosthetic heart valve in the patient in the expanded condition so that the proximal end of the stent is substantially parallel with the valve annulus.

18. The method of claim 17, wherein the implanting step includes deploying the prosthetic heart valve using a transapical procedure.

19. The method of claim 17, wherein the implanting step includes deploying the prosthetic heart valve using a transfemoral procedure.

20. The method of claim 17, wherein the implanting step includes deploying the prosthetic heart valve using a transseptal procedure.

21. The method of claim 17, wherein the implanting step includes implanting the prosthetic heart valve so that the valve assembly is substantially parallel with the valve annulus.
