1. A method of delivering an expandable prosthetic heart valve anchor to a heart of a patient, the method comprising:
positioning the anchor within an anchor catheter, the anchor catheter maintaining the anchor in a collapsed condition;
advancing the anchor catheter to a right atrium of the heart of the patient, through a puncture in an atrial septum of the heart of the patient, and into a left atrium of the heart of the patient;
advancing the anchor catheter from the left atrium of the heart of the patient to a left ventricle of the heart of the patient;
advancing a needle positioned radially within the anchor catheter distally relative to the anchor catheter and through a ventricular wall of the heart of the patient to create a transapical puncture;
advancing the anchor catheter at least partially through the transapical puncture; and
releasing the anchor from the anchor catheter and allowing the anchor to transition from the collapsed condition to an expanded condition while the anchor catheter is positioned at least partially through the transapical puncture,
wherein a balloon catheter is positioned radially inward of the anchor catheter, the balloon catheter including an inflatable balloon at a distal end thereof, the balloon being in fluid communication with the balloon catheter,
wherein the balloon has an inflated condition and a deflated condition, the balloon being in the inflated condition while the needle is advanced through the ventricular wall of the heart of the patient.
