The natural history and postoperative prognosis are generally considered to be poor in the patients with complete form of atrioventricular canal with severe pulmonary hypertension. Surgical results and pre- and postoperative alternation of hemodynamics were assessed in 10 patients with a pulmonary artery to systemic systolic pressure ratio (P_p/P_s) of more than 0.75. The mortality rate was 0% in 3 patients with a pulmonary artery to systemic vascular resistance ratio (R_p/R_s) of less than 0.6 versus 43% in 7 patients with a R_p/R_s of more than 0.6. In 7 survivors, the average value of P_p/P_s fell from 0.95 to 0.56 and that of R_p/R_s fell from 0.57 to 0.36 one year after surgery. In 4-year-old girl with a preoperative P_p/P_s of 1.01 and R_p/R_s of 0.54,though P_p/P_s and R_p/R_s fell to 0.55 and 0.44,respectively, one month after surgery, the former elevated to 0.84 and the latter to 0.68 one year after surgery. Thus, it should be noticed that pulmonary vascular disease deteriorate postoperatively in some of the patients with the age of 4 or more.
