[New approach to the selection of the method of corrective surgery in single heart ventricle]

The work deals with choice of the optimal method for correction of a single heart ventricle. With this in view, the authors studied the anatomy and function of the atrioventricular valves, the volumetric and functional characteristics of the single ventricle, and the condition of the central parts of the pulmonary artery and the subaortic tract in 46 patients with various anatomical forms of the anomaly. Analysis of the results not only helped in specifying the indications for the use of one or another method of correction of the single ventricle but made it possible to determine the optimal volume of the chosen method according to the anatomo-hemodynamic variant of the anomaly and the condition of the vessels of pulmonary circulation. By means of the approach discussed in the work, 4 operations were carried out for forming an artificial interventricular septum and 14 operations for hemodynamic correction in patients with stenosis of the pulmonary artery.
