Fairfax County Supervisor Patrick S. Herrity disclosed Tuesday that he will be undergoing major surgery next month to correct a heart defect.

Herrity, 52, said doctors at Inova Heart and Vascular Institute in Fairfax City plan to perform procedures to correct two problems: an aortic aneurysm and an irregular heart beat known as atrial fibrillation, which first showed up last November.

Herrity, who is married and has two children, said his family has a history of heart problems. His late father, John F. “Jack” Herrity, who served 16 years on the Board of Supervisors, including 12 years as chairman, suffered several heart attacks before receiving a transplant. The elder Herrity died Feb. 1, 2006, of an aortic aneurysm. He was 74.

Pat Herrity, who attended Tuesday’s regular Board of Supervisors meeting and told his colleagues about his plans during closed session, appeared in good spirits.

“It probably hasn’t hit me yet,” Herrity said during a break.

The board also took note of another personal matter Tuesday, observing a moment of silence to mark the death of Lawrence “Larry” K. Schuster Sr., who was Chairman Sharon S. Bulova’s father. Schuster, a World War II veteran who fought in Okinawa, Iwo Jima and Saipan and afterward worked at Champion Paper Co., died March 1, according to an obituary in the Fairfax Connection newspapers. He was 89.
