Implication

Supports use in non-duct-dependent infants; leaves open optimal strategies for duct-dependent cases.

Key Points

To assess the short- and intermediate-term clinical outcomes of balloon aortic valvotomy performed via a carotid cutdown in infants with severe aortic stenosis and to identify determinants of poor prognosis.
Retrospective multicenter registry evaluating 95 infants with severe aortic stenosis treated between 1988 and 1999 across four centers.
Tracked echocardiographic parameters, hemodynamics, complications, and mortality over a mean follow-up of 2.1 years (range: 0 to 9.3 years).
Valvotomy was achieved in 92 of 95 infants, yielding an actuarial 3-year survival of 76 ± 6% and a 3-year freedom from reintervention of 67 ± 6%.
Mortality reached 38% among duct-dependent infants compared with 5% among non-duct-dependent infants.
Predictors of poor outcome in duct-dependent patients were mitral stenosis (p<0.005), a left ventricle not forming the cardiac apex (p<0.005), and an aortic valve diameter under 6 mm (p<0.05).

Population

95 infants with severe aortic stenosis, median age 5 days, median weight 3.4 kg. Includes 51 duct-dependent infants.

Intervention

Balloon aortic valvotomy through a carotid arterial cutdown

Outcome

Short and intermediate term survival and freedom from reinterventionhard clinical

Balloon aortic valvotomy via carotid cutdown provides good intermediate-term results in infants with severe aortic stenosis, though duct-dependent infants have significantly higher mortality.
