[Clinical, diagnostic and therapeutic features of tricuspid infectious endocarditis]. / Osobennosti kliniki, diagnostiki i lecheniia infektsionnogo éndokardita trikuspidal'nogo klapana.

From 1987 to 1998, examination and treatment were conducted of 12 patients with infectious endocarditis of the tricuspid valve (TIE). 11 of them were operated. TIE was clinically characterized by lesser circulation thromboembolism and marked right ventricular failure. TIE was successfully diagnosed by echo-CG (diagnostic sensitivity 83.3%). Serious disturbances of cellular immunity demanded immunocorrection. Indications for surgical treatment are listed.

[Predicting the volume and hemodynamic outcome of radical correction of tetralogy of Fallot on the basis of angio- morphometry]. / Prognozirovanie ob''ema i gemodinamicheskikh rezul'tatov radikal'noi korrektsii tetrady Fallo po dannym angiomorfometrii.

Using the findings from angiographic examination of 91 patients with Fallot's tetrad, the authors developed an angiomorphometric protocol which may predict the feasibility of radical correction of the defect prior to an operation and hemodynamic parameters in the immediate postoperative period, peak right/left ventricular systolic pressure ratios, in particular. The reasons for discrepancy of estimated and measured right/left ventricular systolic pressure ratios were defined and their time course was followed up 12 hours after radical Fallot's tetrad correction in relation to the type of plastic operations.

[The diameter of the descending thoracic aorta in patients with Fallot's tetralogy (angiographic study)]. / Diametr niskhodiashchei grudnoi aorty u bol'nykh tetradoi Fallo (angiograficheskoe issledovanie).

The diameter of the descending thoracic aorta was measured at the level of the diaphragm on angiograms in 91 patients with Fallot's tetralogy. The existence of an exponential dependence of the diameter on the body surface area of patients as well as of healthy individuals was shown. The course of the regression curve in patients with Fallot's tetralogy repeated exactly the course of that in healthy individuals, but the former ran 0.5 mm higher. Thus, to determine the diameter of the descending thoracic aorta in patients with Fallot's tetralogy one may use the nomogram of the dependence of this diameter on the body surface area of healthy individuals or an equation suggested by the authors. It is practically impossible to locate the descending thoracic aorta by means of echography, whereas the size of its diameter is included in equations for calculating the important hemodynamic parameters. The data obtained by the authors allow wider use of noninvasive methods for the diagnosis (echo-morphometry) and prognostication of the results of radical correction of Fallot's tetralogy in a concrete patient.
