A parent vessel lies adjacent heart tissue, and a restriction in the parent vessel is bypassed. A first region of the parent vessel on a first side of the restriction is accessed and an aperture is formed therein. A lumen is formed through the heart tissue, and the lumen communicates with the parent vessel through the first aperture. A second aperture is formed in a second region of the parent vessel on a second side of the restriction. The lumen through the heart tissue communicates with the parent vessel through the first and second apertures, thus bypassing the restriction.
