Crossruff ♦s and ♣s before giving up the ♥ and/or drawing trumps, but that feels and looks a losing line, except if the ♣A appears early. I'd rather play for just over 50% on the trumps splitting 1-1
You can sort of combine the options - start by ducking the heart, win the e.g. heart return, spade to the A, claim if 1-1, else ruff a club, SK, crossruff a bit and hope for Axx in clubs to drop.

Duck the opening lead. West is squeezed if (s)he is 0=3=5=5.
I was looking at this but couldn't get it to work - though that was on my phone with about 3 hrs sleep. Let's try harder: The end position would be
♦AJx opposite
♠x
♥ -
♦x
♣K. This requires a decent amount of effort as South has to become the long trump hand and is
very short on non-ruffing entries. You start by ducking the heart, win the heart return (say), spade J to Ace and we assume West shows out. Now club ruff with S9, SK, heart ruff small, club ruff high, spade to 8, but North still has one trump too many, and South two clubs too many.

Tramticket writes 'East leads the ♥Q, west contributes the 9 (probably standard carding, but E/W formed a partnership on the night and hadn't discussed!).The bidding won't win any beauty contests, but if you can make this 20 HCP slam you won't have to apologise to partner!Things are easy if trumps are 1-1, since you can draw trumps, give up a heart and cross ruff. But you are one trump short to do this if they break 2-0.What is the best plan?'

At double-dummy, In AHydra's reconstruction (left)), declarer can duck East's opening ♥ lead and hope that East fails to find the killing ♦ switch. On any other switch, declarer can succeed by finessing against East's ♠Q. GIB demonstrates that, after a ♥ ruff, South's 2nd trump squeezes West in the minors. Declarer can ruff out whichever minor West abandons.
At single-dummy, I like MikeH's line but, at the table, I would have played ♥A, ♦A, ruff a ♦, ruff a ♣, ruff a ♦, ruff a ♣, ruff a ♦. If ♦KQ or ♣A appear early, then claim. Otherwise concede a ♥ and try to guess the ending... perhaps ruffing a ♥ high and finessing West for ♠Q.
