This is our dad, Titi.He is 56 and he was diagnosed with severe aortic stenosis. He needs an immediate open heart surgery to replace his aortic valve in order to survive.The surgery will reconstruct his big heart and give him the chance to live a normal, long and happy life surrounded by his family.Unfortunately, the cost of surgery and recovery is £15,000, an amount that the family simply cannot raise on such short notice.He is the strongest person we know and he has been there for us through the many challenges in his life, so it's time for us to try and give back all the support we have received.Every child who ever had a sick parent knows the pain and anxiety of not being able to help your parent, but we are hopeful that with your help we'll be able to save him.Dad has given us so many lessons of strength, courage, and dignity and it's our turn to show him that he's not alone. We ask for your support and we are forever grateful for every contribution, hoping that our beloved father gets a new chance.Thank you!His children, Paula and Costin
