After her team lost their first round game, Dixon attended the men's Final Four in Indianapolis, then flew to the women's Final Four in Boston. She attended a Nike party in Boston on Monday, April 3 with a number of other coaches, including Geno Auriemma, and WBCA president Doug Bruno. The following day, Dixon returned to West Point, where she watched the women's final game with her brother. The following day, she collapsed and was rushed to the base hospital. She was next airlifted to Westchester Medical Center in nearby Valhalla, New York. Doug Bruno changed his flight plans to fly to New York to see his former assistant. She was still alive when Bruno arrived, but she died the following day from what her brother described as an "arrhythmic episode to her heart." Dixon died a little over a month shy of her 29th birthday. An autopsy revealed that Dixon had an enlarged heart and had a problem with a heart valve.

The University of San Diego Toreros won the tournament in 2008 and 2009.
In tribute to Maggie's amazing rookie turnaround at Army before her death the Women's Basketball Coaches Association announced the creation of the Maggie Dixon Award for the 2006-2007 season. The award is a "rookie of the year" award for the best coach in their first year as a Division 1 head coach. The inaugural award was given to Krista Kilburn-Steveskey of Hofstra University and the 2007-2008 award was given to Jeff Walz of the University of Louisville. The 2008-2009 recipient was Kelly Packard of Ball State University. The 2009-2010 season clarified the award by excluding former professional coaches moving to D1. The award went to playing great Teresa Weatherspoon despite her coaching several games for Louisiana Tech in 2009 as an interim head coach. She won the Western Athletic Conference tournament returning the Lady Techsters to the NCAA Tournament for the first time in five seasons.
