[Assessment of patients' condition by noninvasive methods of examination in the follow-up after Fontan's operation in atresia of the right atrioventricular ostium]. / Otsenka sostoianiia bol'nykh s pomoshch'iu neinvazivnykh metodov issledovaniia v otdalennye sroki posle operatsii Fontena pri atrezii pravogo atrioventrikuliarnogo otverstiia.

The article discusses the results of using noninvasive methods to study the condition of patients (20) in late-term periods after Fonten's operation in atresia of the right atrioventricular orifice. All patients were subjected to physical examination, electro-, phono- and echocardiography, radiological examination, radioisotope scintigraphy, and left ventriculography. Most patients change to functional class I in the late-term periods after the operation. Though the patients have a sense of well being, the left-ventricular pumping and contractile functions remain disturbed. A tendency towards gradual improvement of these parameters is noted, however. The right atrium is enlarged and its myocardium hypertrophied. Its overexertion increases significantly in physical loading. The blood flow in the lungs becomes normal gradually. The results of various noninvasive methods correlate with one another and with the results of angiocardiography. This allows in some cases to avoid intracardiac examination which presents a certain risk, especially in the first one-two years after Fonten's operation when the mechanisms of cardiac activity compensation are still weak.

[Hypoplasia of the right ventricle with interatrial communication through the coronary sinus]. / Gipoplaziia pravogo zheludochka serdtsa s soobshcheniem mezhdu predserdiiami cherez koronarnyi sinus.

Isolated hypoplasia of the right ventricle is a rare congenital anomaly. The complex defect comprises also a communication between the atria in the form of an oval window or secondary atrial septal defect. The possibility of a communication between the atria via the coronary sinus having in such cases an additional orifice in the left atrium cannot be excluded. In cases of isolated right ventricular hypoplasia the right-to-left shunting goes via the interatrial communication. To eliminate the arterial hypoxemia the interatrial communication has to be closed. When an isolated hypoplasia of the right ventricle is combined with a communication of the coronary sinus with the left atrium, the coronary sinus orifice in the right atrium may be closed by suturing.
