4NT=Bad bid.
3D does not necessarily suggest a hand with slam interest. All 3D means is that partner has at least 5 hearts, at least 4 diamonds, and game-forcing values. When your partner bids 3D here he may just be trying to find the best game contract (3NT, 4H, or 5D).
This is an area in which a lot of people have trouble - many players (even some very good ones) wrongly think that a new suit after a Jacoby transfer promises a big hand.
When partner transfers to hearts and then bids 3D, if you have at least 3-card heart support you should generally bid either 3H or 4H. It makes sense to use 3H as suggesting a better hand than 4H would in order to leave room for partner to cuebid if he has slam interest. Don't worry about him passing 3H since his 3D bid created a game force.
Since your actual hand is a nice one in the context of the bidding, you should bid 3H, not 4H. Leave any slam investigation up to your partner - if his next bid is 4H (it wouldn't be with his actual hand) don't even look at your hand - just Pass - you have already told your story and partner has signed off.
