Hemodynamic effects of bidirectional cavopulmonary shunt with pulsatile pulmonary flow.

摘要: The effects of "pulsatile" bidirectional cavopulmonary shunt (BCPS) produced by the flow from ventricle or Blalock-Taussig (B-T) on ventricular function and pulmonary circulation were evaluated in 10 patients with univentricular heart 3 to 37 months (mean, 16.6 +/- 9.5 months) after surgery. Age at operation ranged 7 15 years 5.5 4.5 years). In addition BCPS, was supplied a B-T contralateral side BCPS five patients, through stenotic valve four both one patient. There no operative deaths; however, there two late deaths acute respiratory infection 13 operation.
