Vice President Dick Cheney.
WASHINGTON (CNN)–Vice President Dick Cheney completed surgery at George Washington University Hospital to replace his defibrillator on Saturday.
Cheney arrived at the hospital in the morning with his wife Lynne for what is described as minor surgery and left a little over four hours later.
"The Vice President visited his doctors from the Medical Faculty Associates of George Washington University today for scheduled replacement of his implantable cardioverter-defibrillator (ICD)," said Megan McGinn, Cheney's spokeswoman. "The device was successfully replaced without complication. The Vice President has returned to his home at the Naval Observatory and has resumed his normal schedule."
The defribillator was orginally placed in Cheney's chest in 2001 to shock his heart in case of an irregular heatbeat.
The procedure to replace the 2001 device was expected to last anywhere from 30 minutes to an hour and usually occurs while the patient is under heavy sedation rather than general anesthesia and requires no overnight observation.
