Method and system for transcatheter intervention
A method for accessing a mitral valve that includes forming an incision and inserting a first catheter comprising a lumen. The first catheter is adapted to be directed towards a left atrium and the first catheter has a working length of approximately 15 cm to approximately 52 cm. The method further includes utilizing a trocar in the first catheter to penetrate a pericardium and utilizing the trocar to penetrate the left atrium. The method further includes accessing the mitral valve from an antegrade direction.
1. A method for accessing a mitral valve, the method comprising:
forming a suprasternal incision;
inserting a retractor into the suprasternal incision, the retractor adapted to elevate a sternum;
illuminating, via at least one of the retractor and an endoscope introduced into the incision, an inside of the incision;
opening a pericardium under visualization aided by at least one of the endoscope and the retractor;
separating an aorta and a superior vena cava to facilitate access to a roof of a left atrium;
illuminating, via at least one of the retractor and the endoscope, the roof of the left atrium;
placing a suture into the left atrium under visualization aided by at least one of the retractor and the endoscope;
passing at least one of a guide wire and a catheter into the left atrium proximate the suture;
advancing at least one of the guide wire and the catheter through a mitral valve;
deploying a mitral valve repair device;
withdrawing the catheter or the guide wire;
securing the suture;
removing the retractor; and
closing the incision.
2. The method of claim 1 , wherein the incision is superior to a sternal notch.
3. The method of claim 1 , comprising inserting an endoscope into the incision, the endoscope being adapted to aid passage of instruments into the incision.
4. The method of claim 1 , comprising utilizing a steering wire to direct at least one of the catheter and the guide wire towards the left atrium.
5. The method of claim 1 , comprising utilizing a trocar to penetrate the left atrium.
6. The method of claim 1 , comprising utilizing a trocar to penetrate the pericardium.
7. The method of claim 1 , comprising:
reducing a pressure within the aorta; and
displacing the aorta.
8. The method of claim 7 , wherein the displacement of the aorta is to the left.
9. The method of claim 1 , wherein the suture is a purse string suture.
10. A method for accessing a mitral valve, the method comprising:
forming a suprasternal incision;
illuminating an inside of the incision;
opening a pericardium under visualization, aided by at least one of an endoscope and a retractor;
separating an aorta and a superior vena cava to facilitate access to a roof of a left atrium;
illuminating a roof of a left atrium;
placing a suture into the left atrium under visualization;
passing at least one of a guide wire and a catheter into the left atrium proximate the suture;
advancing at least one of the guide wire and the catheter through a mitral valve;
deploying a mitral valve repair device;
withdrawing the catheter or the guide wire;
securing the suture; and
closing the incision.
