1. A method comprising:
inserting a catheter into a right atrium of a heart of a subject;
advancing a distal portion of the catheter toward a roof of the right atrium;
deploying a flexible longitudinal member from the catheter, such that a deployed portion of the flexible longitudinal member is loop-shaped;
contacting, with the deployed portion of the flexible longitudinal member, a single stabilization site located entirely superior to a fossa ovalis of the heart (a) on the roof of the right atrium, (b) between the roof and an interatrial septum of the heart, or (c) on the interatrial septum superior to the fossa ovalis of the heart;
deploying a needle from the catheter;
while the deployed portion of the flexible longitudinal member is in contact with the single stabilization site, bringing a distal end of the needle in contact with a hole site on a surface of the interatrial septum outside the fossa ovalis;
forming a hole through the interatrial septum at the hole site with the needle; and
withdrawing the deployed portion of the flexible longitudinal member toward the catheter.
