1. A method of deploying a heart implant in a heart of a patient, the method comprising:
inserting, through a first vascular access site in the patient, a first catheter having a distal magnetic head and a posterior anchor and advancing the first catheter to a first location in the heart;
inserting a second catheter having a distal magnetic head through a second vascular access site in the patient and advancing the second catheter to a second location in the heart, the first and second locations being separated by a tissue wall;
positioning the first and second catheters such that the distal magnetic heads of the first and second catheters magnetically couple across the tissue wall;
penetrating the tissue wall with a penetrating guidewire advanced through the first and second catheters while magnetically coupled;
advancing a bridging element coupled to the posterior anchor through the penetrated tissue wall and into the second catheter while the distal magnetic heads of the first and second catheter remain magnetically coupled;
deploying the posterior anchor from the first catheter at the first location in the heart with the first catheter; and
advancing an anterior anchor along the bridging element from the second vascular access site and deploying the anterior anchor at a third location in the heart and coupling to the bridging element spanning across a chamber of the heart.
