(American Association for Thoracic Surgery) A new study, presented today at the AATS 101st Annual Meeting, shows an association between decreased survival at five years and leaving an atrial communication at biventricular repair of unbalanced AVSD after adjusting for other known risk factors. The study sought to determine factors associated with mortality after biventricular repair of AVSD.
