Abstract

Tetralogy of Fallot is the most common blue type congenital heart defect. Reconstruction of the right ventricular outflow tract for this defect is a procedure associated with the main reasons for repeated surgical interventions. Despite all efforts to develop various methods of preserving the pulmonary valve, in 30–40% of cases transannular repair of the right ventricular outflow tract is required. Postoperative pulmonary valve insufficiency over time leads to right ventricular dysfunction and requires repeated interventions.

Amirghofran A. et al. proposed a new approach to reconstruction of the right ventricular outflow tract by creating a pulmonary artery neovalve from the right atrial appendage. The use of this method has proven to be effective for eliminating deficiency and its consequences. The article presents clinical experience of neovalve implantation from the right atrial appendage into the right ventricular outflow tract in patients undergoing radical correction of tetralogy of Fallot.
