A Sound Investigation

Tschritter et al report a case of a 32-year-old woman with complete transposition of the great arteries presented with progressive dyspnea. She had a history of initial balloon atrial septostomy and 2 atrial switch repairs by Mustard procedure. Her specific complaints were increasing fatigue, respiratory problems with exertion, and mild limitation of activity. Based on the clinical presentation and the results of imaging studies, congestive heart failure, New York Heart Association Class II, was considered to be the most likely diagnosis. Chronic volume and work overload of the systemic ventricle were probably responsible.
