At first I was thinking that this meant that the doctor had lost all the hearts for the transplants. It IS the medical unit after all!
Yayyy! Now I can do Duolingo on my phone without all the hassle of redoing the whole lesson multiple times because of typos or me not being able to type on my phone.

Does the phrase relate to 'I lost all heart' which is an English idiom for giving up/losing hope, or quite literally losing hearts? (!!!)
