Supports open valvotomy in infants with critical aortic stenosis; leaves open need for larger studies on durability versus alternatives.
Burch et al. (1990) conducted an observational in Critical aortic stenosis (n=13). Open valvotomy was evaluated on Operative survival. Open valvotomy in 13 infants with critical aortic stenosis resulted in 100% operative survival, with two late deaths and impaired left ventricular function at a median follow-up of 2.9 years.
