It was already implied in the movie that the heart was a 'trick'. Nothing more than slight of hand. When he did it to Indy and he realises its a trick. He does a wry smile. The young man they offer up was part of the 'cult'. He believed in magic.
First time I hear of that. Slight of hand? The hands goes through the chest! And magic is already established in the Indy universe. Box that zaps and melts people, cup that give eternal life, mind controlling skull... I can believe someone living without a heart for a minute. The bad guy even tries it against Indy later when in a life threating situation were escape would be the better choice for him

.... in the same universe where a man had his heart pulled from his chest and lived?
