VACTERL Association Diagnosis and Management

Introduction to VACTERL Association

The American College of Cardiology and other medical societies recognize VACTERL association as a non-random association of congenital birth defects, including vertebral anomalies, anal atresia, cardiovascular malformations, tracheo-esophageal fistula, esophageal atresia, renal anomalies, and limb abnormalities, with a diagnosis requiring at least 3 of these cardinal features, and tracheoesophageal fistula and cardiac defects being among the most common components 1, 2

The American College of Cardiology notes that cardiovascular anomalies occur in 60-77.8% of VACTERL patients, making cardiac defects one of the most frequent components of this association, with common cardiac lesions including ventricular septal defect (VSD), atrial septal defect (ASD), patent ductus arteriosus (PDA), tetralogy of Fallot (TOF), and transposition of the great arteries (TGA) 2, 3
The Journal of the American College of Cardiology recommends standard management per congenital heart disease guidelines for cardiac lesions, with VSD closure indicated when there is left ventricular volume overload and Qp:Qs >1.5 3

Tracheoesophageal fistula with or without esophageal atresia is present in 44.4-77.8% of VACTERL cases, with associated airway complications including tracheal diverticula at the site of repaired fistula, and tracheomalacia (37.4-89.2% of EA-TEF patients) 4, 5, 6

The American College of Cardiology suggests that when VACTERL is suspected, systematically evaluate for vertebral/rib anomalies, anal atresia, renal anomalies, limb defects, and single umbilical artery, and coordinate multidisciplinary care involving pediatric surgery, cardiology, and other subspecialties based on specific defects present 1, 2
For the tracheoesophageal component, maintain high suspicion for recurrent TEF (occurs in 5-14% of cases) if respiratory symptoms persist, and consider combined bronchoscopy and endoscopy for diagnosis, as recommended by the Nature Reviews Gastroenterology and Hepatology 4, 7

The majority of VACTERL patients have normal intelligence, but developmental concerns may arise from multiple congenital anomalies affecting function, prolonged hospitalizations, and surgical interventions, as noted by the American College of Cardiology and the Journal of the American College of Cardiology 2, 3, 5
