Balloon Valvuloplasty for Critical Aortic Stenosis in a Low Birth Weight Baby with Tracheoesophageal Fistula

The use of valvuloplasty in low birth weigh infants with valvular aortic stenosis has not been widely repotted. We report a 1556 g 3-day-old female infant with complex heart disease including critical valvular aortic stenosis, bicuspid aortic valve, mitral stenosis, patent ductus arteriosus and secundum type atrial septal defect. She also had esophageal atresia with a distal tracheoesophageal fistula and trisomy 18. Balloon valvuloplasty was considered to be more dangerous in this patient than in infants with simple critical aortic stenosis without other associated anomalies or low birth eight. Retrograde aortic balloon valvuloplasty was done carefully with the patient intubated and mechanically ventilated. We successfully dilated the stenotic aortic valve which resulted in a dramatic decrease of the left ventricular pressure from 139/12 mm Hg to 81/11 mm Hg. Despite the high operative risk and poor prognosis balloon valvuloplasty may be the first feasible step towards the survival of low birth weight infants with valvular aortic stenosis.
