Around 550 people in Ireland are waiting for life-saving organ donor transplants.
Next week marks Organ Donor Awareness Week, which runs from the 2nd to 9th of April.
Maurice Kavanagh has had a heart and kidney transplant, as well as surviving cancer.
He said when he first found out he needed a transplant he thought it was a death sentence.
Speaking to Newstalk Breakfast, Maurice explained that "I never heard of a heart transplant - I reckon it's only when it lands on your own doorstep that you sort of come to terms with it and do more research on it.
"It was like a death sentence - that's what I thought it was. I thought 'never in a million years am I going to get a heart'," he added.
Maurice explained that after two false alarms he finally received the call guaranteeing his transplant.
"I was at home making a pot of stew, and my bleeper went off... You have a five-hour timeframe to get from where you are to the Mater Hospital... Thankfully I wasn't too far away".
Maurice is encouraging people to get a donor card if they have not already. "I look at myself... 21 years this year I have a heart, and five years a kidney... Please, please people - carry a donor card," he concluded.
