First, Palpatine did not know the truth about what had happened to Padme. But it was more fun to tell Vader that he had killed her to anger him.

When Anakin had to choose between losing Padme — fearing that she might die in childbirth — or turning to evil to “save” her from death, he chose evil. His desire to “save” her at all costs led Anakin to the dark side. For him, the dark side became a means of saving his loved one.

Palpatine tells Darth Vader that in his anger he killed her, placing the blame for Padmé's death on Vader. Vader denies it, saying he sensed Padmé was still alive, which the audience knows she was as Obi-Wan escaped on the ship with her.
Sadly the Clone Wars would have still happened, but Padmé would have also survived, giving birth to Luke and Leia who would have probably been inducted into the Jedi Order. As for what would have happened between the two, with their marriage and all, that's a bit tricky.
Anakin's vision did come true, as Padmé, heartbroken by her husband's downfall, loses her will to live and succumbs while giving birth to twins. Before her death, Padmé still believed there was still good left in Anakin and that one day he could be saved with the help of their children.
