2006 was the best year of her career. In April she competed in Shanghai at the 2006 FINA World Swimming Championships, where she won two gold medals, the 50m backstroke, and the 100m backstroke. She won both gold medals by exactly a quarter of a second over second place.

In Budapest at the long-course 2006 European Aquatics Championships in late Summer, she won a gold medal in the 50m backstroke, and a bronze in the 100m backstroke. That December in Helsinki at the 2006 short-course European championships, she won two more gold medals, the 50 m backstroke and 4x50m medley. In her last international success to date, at the 2007 short-course European championships she won gold in the 4x50m relay, silver in the 50m backstroke, and bronze in the 100m backstroke.

Pietsch’s first success on an international stage was at the 2001 European Short Course Swimming Championships in Antwerp, where she won one silver medal, in the 4x50m medley and three bronze medals, in the 50m backstroke, 100m backstroke, and 4x100m freestyle relay. She would win another silver and two more bronze medals the next year in 2002. Between 2003 and 2005 she would win a further five silvers and one bronze in three European short course championships. In 2004, she competed in her only Olympic race, the 100 m backstroke. She finished seventh in her heat, and 23rd overall.
