piggyback transplant
n.— «Jackson had an emergency heart transplant in 1991. Doctors put the new heart beside the old one. The procedure, called a heterotopic transplant, is much rarer than the traditional orthotopic transplant, where the native heart is removed and replaced with a heart from a donor.…The procedure is sometimes called a “piggyback” transplant.» —“Minister’s hearts filled with joy now that his life is more normal” by Samantha Epps in Anderson Sun News (Myrtle Beach, S.C.) Nov. 10, 2005. (source: Double-Tongued Dictionary)
