Former Vice President Walter Mondale on Wednesday had heart surgery at Mayo Clinic in Rochester.

The surgery, which a statement said was "successful," came just a few days after Joan Mondale, the vice president's wife, passed away. Joan Mondale, 83, died on Feb. 3 and was memorialized on Feb. 8.

"Mr. Walter Mondale underwent successful heart surgery this morning at the Mayo Clinic in Rochester. He is resting comfortably and is expected to make a full recovery," said a statement. "His family requests privacy at this time."

Mondale is 86 years old.
