Lampson went for a routine checkup at the national Naval Medical Center on Friday and his doctor noted some irregularities, said Bobby Zafarnia, a spokesman for the Texas Democrat.
"They got in touch with his doctors in Houston, he was going to head to the district anyway, they recommended he come in immediately for a checkup and that's when they decided to do the bypass," Zafarnia said.
The surgery was done Sunday to treat blockages of arteries on the surface of his heart and was performed at St. Luke's Episcopal Hospital in the Texas Medical Center in Houston.
News of the surgery was not released until Monday because information had to be coordinated with doctors and the hospital, but the House leadership was informed, Zafarnia said.
Lampson, 62, should be in recovery in the hospital for at least a week. The House is voting on budget issues this week and Lampson likely will miss those votes. A full recovery could take three to four weeks.
"The physicians have indicated that the surgery proceeded well, and that Congressman Lampson will make a full recovery," Zafarnia said. "Though this was a serious procedure, Congressman Lampson has his family with him, his spirits are high, and he looks forward to returning to his office and serving his constituents as quickly as possible."
Lampson was hospitalized briefly in December, soon after he won election to the seat previously held by DeLay, a Republican. He underwent an angioplasty procedure at the time to open up a partially blocked vessel.
