[Complications of the Waterston-Cooley-Edwards anastomosis and their correction in radical surgery of the tetralogy of Fallot].

The work is based on the analysis of complications of Waterston-Cooley-Edwards anastomosis which create tactical and technical difficulties in correction of Fallot's tetralogy. Rational methods for their correction are suggested. From January, 1982 to April, 1989 a total of 133 radical operations were carried out for Fallot's tetralogy in patients with Waterston-Cooley-Edwards anastomosis formed earlier; mortality was 6%.

[Results of the use of a graft with a monocusp in radical correction of Fallot's tetrad].

The article deals with the results of complex study of the effect of pulmonary insufficiency on intracardiac hemodynamics and function of the heart in the immediate and late-term periods after radical correction of Fallot's tetralogy. Answers are also given to questions concerning the expediency of the use and functional adequacy of a xeno-pericardial monocusp in the closure mechanism of the pulmonary artery valve. The study showed that massive pulmonary regurgitation has a negative effect on the functional condition of the right ventricle in late-term postoperative periods.

[The use of personal computers in the angiocardiometric evaluation of the pulmonary artery in complex congenital heart defects].

Application of personal computers in angiocardiometric assessment of the pulmonary artery in such congenital heart diseases as Fallot's tetralogy and total transposition of great vessels made it possible to set up a convenient data bank allowing one to store numerical and textual information, conventionalized drawings of pulmonary arteries showing the degree and location of stenosing lesions and color-marked data on surgically significant constrictions. The system has a rich visual presentation of data and allows for convenient and quick search and processing of information (including the use of standard statistic, graphic, and other present-day packages of analysis and presentation of medical information).
