Up For Review suffered a fatal injury after being brought down at the first fence of the Grand National.
The horse, a 25-1 shot, became the first fatality in the race since 2012 as Tiger Roll won for a second successive year at Aintree.
Broadcaster ITV later showed a replay of the race from the second fence to avoid broadcasting the fall.
General Principle was taken away in a horse ambulance after sufferring superficial injuries, a day after two horses were put down on the penultimate day of the festival.
The hot favourite, ridden by jockey Davy Russell, kept out of trouble in the 40-horse field to emulate the feat of National great Red Rum 45 years ago.
Up For Review is tended to after falling at the first.
Tiger Roll, the smallest horse in the race, won by three lengths from Magic of Light, Rathvinden and Walk In The Mill.
Winning owner Michael O’Leary said: “It’s unbelievable. It’s a phenomenal training performance by Gordon. It’s brilliant that he keeps bringing this horse back at Cheltenham better than ever and Aintree better than ever.
“And what a ride by Davy – fantastic. It’s unbelievable, to win two Grand Nationals is just incredible.
“It’s a great result for the punters as well.”
For much of the way it looked like Ruby Walsh might seal his third National success as his mount Rathvinden raced and jumped with zest on the front end, along with stablemate and last year’s narrowly beaten runner-up Pleasant Company.
Tiger Roll eased to victory.
However, Tiger Roll was always in their slipstream and it was clear on the run to the final fence that barring accidents he would seal victory, with Russell still motionless in the saddle.
Jessica Harrington’s mare Magic Of Light attempted to chase him down, but Tiger Roll was not for catching and passed the post comfortably ahead.
It was a third National success for Elliott – having first struck gold as a fledgling trainer with Silver Birch in 2007.
