PURPOSE: Truncus arteriosus is a complex and heterogeneous form of @entity4297 . Many of the risk factors from several decades ago, including late repair and interrupted aortic arch, have been mitigated through better understanding of the entity and improved surgical techniques. However, @entity340 remains an important cause of morbidity and mortality. The purpose of this study was to evaluate the anatomic factors associated with @entity340 and the need for truncal valve surgery. METHODS: This was a retrospective review of 72 @entity1 who underwent repair of truncus arteriosus at our institution. The median age at surgery was nine days, and the median weight was 3.1 kg. Preoperative assessment of @entity338 by echocardiography revealed no or trace insufficiency in 30, mild in 25, moderate in 10, and severe in 7. The need for truncal valve surgery was dictated by the severity of @entity338 . RESULTS: Sixteen (22%) of the 72 @entity1 undergoing truncus arteriosus repair had concomitant truncal valve surgery. Anatomic factors associated with the need for truncal valve surgery included an abnormal number of truncal valve cusps (P < .005), presence of @entity340 (P < .005), and the presence of an anomalous coronary artery pattern (P < .005). Fifteen (94%) of the sixteen @entity1 who underwent concomitant surgery had two or all three of these anatomic factors (sensitivity = 94%, specificity = 85%). CONCLUSION: This study demonstrates that the presence of specific anatomic factors was closely associated with the presence of @entity338 and the need for concomitant truncal valve surgery. Preoperative evaluation of these anatomic factors may provide a useful tool in determining who should undergo concomitant truncal valve surgery.
