Stage approach in the surgical treatment of congenital valvular diseases with univentricular hemodynamics

We have analyzed the study results of staged surgical repair of patients having complex cyanotic congenital valvular diseases with univentricular hemodynamics. The stage correction of valvular disease was made in 26 patients. The first stage of palliation included either performing pulmonary to systemic bypass because of pulmonary blood flow deficiency or pulmonary artery narrowing because of excessive pulmonary blood flow. As a second stage repair we preferred bidirectional Glenn bypass. Subsequently some of the children underwent total cava-pulmonary bypass. The results obtained allowed us to conclude that palliative surgeries are efficient in improving total status of patients, relative normalizing pulmonary blood flow and preparing lesser circuit to the next stage of surgical palliation.
