Heartfelt reunion for Bubba

BILL Clinton caught up with an old acquaintance — a surgeon who helped saved his life in one of his famous major heart surgeries — in unusual circumstances, Page Six hears.

Sources say that famed chef Donatella Arpaia got a visit from the Secret Service on Wednesday about a “highly recognizable person” who wanted to dine at her new Miami restaurant, Noma Beach at Redfish.

We’re told they even asked the chef to prepare a vegan menu for the notable guest, who wanted to host a table of 12.

But at the last minute, the security team told Arpaia that their man wouldn’t be able to come after all because they wouldn’t be able to secure the restaurant since the entire dining space is in direct contact with the Atlantic Ocean.

But Arpaia guessed that the special guest was the former commander in chief — who, as it so happens, her husband, Dr. Allan Stewart, operated on almost 19 years ago in New York.

Page Six hears that when Clinton learned about Arpaia’s relationship with Dr. Stewart, he immediately invited them to join the intimate lunch at the party of 12’s new location — the Biltmore Hotel.

(Lucky for the president he’d been keeping up with his heart-healthy diet when he ordered the vegan menu from Arpaia’s place and hadn’t been trying to sneak a double cheeseburger — or he might have some tough questions to answer from the doctor).

We’re told Arpaia arrived with a vegan chocolate cake for the 42nd president with a message on it that read, “Celebrating 19 years” — and that Dr. Stewart remarked, “He looks healthier now than when he came for surgery.“

Clinton has had a series of heart operations, beginning with a headline-making quadruple bypass in 2004.

Dr. Stewart was a member of the three-person cardiac surgical team who performed that procedure.
