Proximal tab for side-delivered transcatheter heart valves and methods of delivery
A prosthetic heart valve includes a valve frame defining an aperture that extends along a central axis and a flow control component mounted within the aperture. The valve frame includes a distal anchoring element and a proximal anchoring element. The valve frame has a compressed configuration to allow the valve to be delivered to a heart of a patient via a delivery catheter. The valve frame is configured to transition to an expanded configuration when released from the delivery catheter. The valve is configured to be seated in a native annulus when the valve frame is in the expanded configuration. The distal and proximal anchoring elements configured to be inserted through the native annulus prior to seating the valve. The proximal anchoring element is ready to be deployed subannularly or is optionally configured to be transitioned from a first configuration to a second configuration after the valve is seated.
1. A method of delivering a prosthetic heart valve to an annulus of a native valve between an atrium and a ventricle of a heart of a patient, the method comprising:
disposing in the atrium of the heart adjacent to the annulus of the native valve a distal end of a delivery catheter having disposed in a lumen thereof the prosthetic heart valve, the prosthetic heart valve having a valve frame with a distal anchoring element and a proximal anchoring element, and a flow control component mounted within the valve frame, the prosthetic heart valve being in a compressed configuration within the lumen of the delivery catheter;
releasing the prosthetic heart valve from the lumen of the delivery catheter into the atrium such that the prosthetic heart valve transitions from the compressed configuration to an expanded configuration in response to the releasing;
placing a portion of the distal anchoring element on a ventricle side of the annulus of the native valve;
seating the prosthetic heart valve in the annulus of the native valve when the prosthetic heart valve is in the expanded configuration and the proximal anchoring element is in a first configuration; and
transitioning the proximal anchoring element from the first configuration to a second configuration after the seating the prosthetic heart valve in the annulus.
2. The method of claim 1 , wherein the native valve is a native tricuspid valve, the placing the portion of the distal anchoring element on the ventricle side of the annulus includes placing the portion of the distal anchoring element in a right ventricular outflow track (RVOT).
3. The method of claim 1 , wherein the proximal anchoring element when in the second configuration is in contact with subannular tissue on a proximal side of the annulus of the native valve.
4. The method of claim 1 , further comprising:
transitioning, after the seating the prosthetic heart valve in the annulus, a tensile member coupled to the valve frame from a first configuration in which the proximal anchoring element is in its first configuration to a second configuration in which the proximal anchoring element is allowed to transition to the second configuration.
5. The method of claim 4 , wherein at least a portion of the tensile member extends through a waypoint defined by the valve frame.
6. The method of claim 4 , wherein the proximal anchoring element is compressed in the first configuration and the proximal anchoring element is expanded in the second configuration.
7. The method of claim 4 , wherein the transitioning the tensile member from the first configuration to the second configuration includes decoupling the tensile member from the proximal anchoring element.
8. The method of claim 4 , wherein the tensile member is one of a suture, a cable, or a wire.
9. The method of claim 4 , wherein a coupler of the tensile member releasably couples at least a portion of the tensile member to the proximal anchoring element.
10. The method of claim 9 , further comprising:
decoupling the coupler to allow the tensile member to transition to its second configuration.
11. The method of claim 9 , wherein the coupler is at least one of a threaded coupler or a ball and cup coupler.
