Abstract
Methods, apparatuses, and systems for performing a valve replacement or repair. Apparatuses may include systems and may include an outer catheter, one or more interchangeable inner catheters, a guidewire and an expandable chordae tendinae deflector. Also described herein are rapid pacing sheaths that may be used with any of these apparatuses and methods.
Claims28
A method for percutaneous antegrade delivery and implantation of a valve in a patient, the method comprising:
- advancing a first inner catheter that is distally tapered into a left atrium through a transseptal puncture, wherein a distal region of the first inner catheter is flush with an outer catheter at a distal end region of the outer catheter;
- expanding an expandable deflector to deflect away from the chordae tendinae of the left ventricle;
- advancing the outer catheter and either the first inner catheter or a second inner catheter that has been exchanged for the first inner catheter, so that the first or second inner catheter is in a left ventricle while deflecting away from the chordae tendinae;
- advancing a guidewire out of the distal end of the first or second inner catheter and across a valve of the patient's heart;
- removing the first or second inner catheter, leaving the guidewire in place, and
- implanting a replacement valve in the patient's heart through the outer catheter.

A method for percutaneous antegrade delivery and implantation of a valve in a patient, the method comprising:
- advancing a first inner catheter that is distally tapered through a transseptal puncture, wherein a region of the first inner catheter proximal to a distal end of the first inner catheter is annularly engaged to an outer catheter at a distal end region of the outer catheter so that an outer surface of the first inner catheter is flush with an outer surface of the outer catheter without a gap;
- deflecting the first inner catheter within the left atrium so that a distal end region of the inner catheter assumes a first bend;
- expanding an expandable deflector to deflect away from the chordae tendinae of the left ventricle;
- advancing the outer catheter and either the first inner catheter or the second inner catheter that has been exchanged for the first inner catheter so that the first or second inner catheter is in the left ventricle while deflecting away from the chordae tendinae;
- deflecting the first or second inner catheter within the left ventricle so that the distal end region of the first or second inner catheter assumes a second bend and faces the patient's left ventricular outflow tract;
- advancing a guidewire out of the distal end of the first or second inner catheter and across an aortic valve of the patient's heart;
- removing the first or second inner catheter, leaving the wire in place, and implanting a replacement aortic valve in the patient's heart through the outer catheter.
