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.

Abstract: A method and system for performing transseptal extracorporeal membrane oxygenation is disclosed. The method may include puncturing a septum between the right atrium and the left atrium and advancing a catheter system through the puncture and into the aorta. A first portion of the catheter system can remove blood from the patient, in some examples near the inferior vena cava. A second portion can return oxygenated blood to the patient, through the transseptal puncture and into the aorta.

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 and a guidewire. The inner catheter(s) may be detachably coupled to the outer catheter. The inner catheter and outer catheter may surround the guidewire such that the inner and outer catheters may be advanced in a monorail fashion within the patient. Example methods may include percutaneously inserting the outer and inner catheter(s) into an artery and advancing toward the right atrium, through a transseptal atrial puncture, and advanced to the left atrium and left ventricle to access the aortic valve.
