1. A shaped catheter configured for advancement into a subvalvular space of a heart comprising:

  • an elongated member comprising a proximal end, a distal end, and a lumen therethrough, and further comprising an aortic arch curve region defining a first plane, a transition curve region distal to the aortic arch curve region and defining a second plane at a first angle with respect to the first plane, and a valve curve region distal to the transition curve region and defining a third plane at a second angle with respect to the second plane,wherein the aortic arch curve region comprises a first preformed curve that corresponds to a curve of an aortic arch and has a first arc defining a central angle of about 60°

    to about 270°

    , the transition curve region comprises a second preformed curve that corresponds to a curve between an aortic root and a subannular groove of a mitral valve and has a second arc defining a central angle of about 90°

    to about 270°

    , and the valve curve region comprises a third preformed curve that corresponds to a curve of the subannular groove of the mitral valve and has a third arc defining a central angle of about 60°
