1. A theoretical and a transformed formula was derived as to what extent RV outflow tract stenosis should be relieved to lower RV/LV pressure ratio below a certain value post-operatively in corrective surgery of tetralogy of Fallot. Values obtained from the theoretical formula correlated well with actual values in thirteen cases operated on. Relationship between degree of constriction and pulmonary flow was analyzed graphically. Experiments showed that critical stenosis was reached at the smaller degree of circumference constriction at greater thickness to circumference ratio of the pulmonary artery. Theoretical and experimental results were not concordant as to flow through Blalock and Waterston anastomosis. Further study should be required.
