Does open surgical correction improve survival and clinical outcomes in patients with tetralogy of Fallot?
Answers are grounded in this paper and cite their sources.
Open surgical correction of tetralogy of Fallot is feasible, with an 18% operative mortality over 5 years, and results in normal physical activity and hemodynamics in the majority of survivors.
Fifty patients with tetralogy of Fallot have had surgical correction of their complex defects made possible by the open technic during the past 5 years. The overall 5-year operative mortality was 18 per cent. This was reduced to 15 per cent during the past 2 years in 20 patients. Forty-one of the patients are alive, asymptomatic, and have normal physical activity. Ffteen patients have had cardiac evaluation studies including cardiac catheterization from 1½ to 3 years postoperatively. Thirteen patients had normal cardiac hemodynamics. In only two patients was there evidence of incomplete hemodynamic improvement even though marked clinical improvement was gained.

Kay et al. (1961) conducted an observational in Tetralogy of Fallot (n=50). Surgical correction by open technic was evaluated on 5-year operative mortality. Surgical correction of tetralogy of Fallot using the open technic resulted in an overall 5-year operative mortality of 18%, with 41 of 50 patients alive and asymptomatic.
