[Solitary cardiac metastasis from carcinoma of the cervix]. / Solitární metastáza v srdci u karcinomu delozního cípku.

Authors report the case of 37 years old women after radiotherapy for spinocelular cervical carcinoma which was presented by a solitary metastasis in the right ventricle causing right ventricle output tract obstruction. Cardiosurgical intervention as well as chemotherapy were not indicated for the great extension of cardiac involvement. The patient died from a massive pulmonary embolism. Echocardiography, although limited by the discrimination ability, seems to be the best method for the cardiac metastasis detection.

[Double-chambered right ventricle]. / Zdvojená pravá komora srdecní.

Treatise on double-chambered right ventricle discussing its possible embryonal development studies 3 cases from a group of 568 congenital heart malformations (collected between 1972 and 1994) and compares them with the information from literature.

[The common cardiac ventricle]. / Spolecná komora srdecní.

Morphology of common (single) ventricle, primitive ventricle, huge defect of ventricular septum and residual apical septum were described according to a group of 27 autopsies studied between 1972 and 1987 and comparative information from the literature. Nomenclature and differential diagnostics were discussed.

[The conduction system in the common cardiac ventricle]. / Prevodní systém u spolecné srdecní komory.

Conductive system in selected cases of common ventricle was studied by serial histological sections and compared with information from the literature. Results of the study showed that morphology and topography of conductive system suited to principles of concordance and discordance of atriums and ventricles. presence or lack of inflow ventricular septum were crucial for discrimination of ventral or dorsal conductive system. They both can be present in atrioventricular discordance.

[The heart conduction system in corrected transposition of the great vessels]. / Srdecní prevodní systém u korigované transpozice velkých arterií.

Authors collected 110 cases of transposition of great arteries between 1972 and 1989. Nine transpositions were corrected and the conduction system was studied on histological serial sections in 6 of them. Two cases of corrected transposition without septal or any other defect were described in detail, one in situs solitus, another in situs inversus. According to the literature, an anterior conduction system often tends to develop in situs solitus, and posterior conduction system in situs inversus. Two presented cases as well as other cases in situs ambiguous quoted in authors' and other papers showed that an arrangement of conduction system in corrected transposition does not depend on general visceral situs but on mutual position of atrial and ventricular septa instead.

[Defects of the atrioventricular cardiac septum (persistent common atrioventricular canal)]. / Defekty atrioventrikulárního srdecního septa (canalis atrioventricularis communis persistens).

A new morphological-clinical classification was suggested for this type of heart malformations based on confrontation of authors' results with literature. The classification took into consideration appearance of the top of ventricular septum, form of atrioventricular valves, topography of the defect and its relation to the location of conducting system.

[Aortopulmonary window in 10 children]. / Aortopulmonální okénko u 10 detí.

The authors present their diagnostic and therapeutic experience with aortopulmonary window in 10 children. As it threatens, in particular if combined with other heart diseases, the majority of children with development of early irreparable changes in the pulmonary circulation it is important to diagnose the defect, preferably by echocardiography and treat it already in childhood.

[Location of the bundle of Kent in patients with Ebstein's anomaly of the tricuspid valve]. / Lokalizace Kentova svazku u pacientu s Ebsteinovou anomálií trikuspidální chlopne.

The prequisite of better therapeutic results in patients with Ebstein's anomaly of the tricuspid valve is more perfect diagnosis not only of the severity of the malformed valve but also of other associated defects incl. the anomalous accessory bundle of Kent which causes the development of dangerous tachydysrhythmias. The authors present their own experience with the localization of the bundle of Kent by mapping the endocardium of the atria in seven children before a cardiac operation. In all ventricular preexcitation type B with the bundle of Kent in the posterior lower portion of the atrial septum was found. In two non-operated patients who died with tachydysrhythmia which could not be controlled, the bundle of Kent was confirmed by histological examination, in three it was severed by operation, two patients are waiting to be operated. The authors recommend interruption of the bundle of Kent always concurrently with operation of the malformed tricuspid valve and other associated cardiac defects.

[Ebstein's anomaly of the tricuspid valve with the WPW syndrome]. / Ebsteinova anomálie trikuspidální chlopne s WPW-syndromem.

Case-history of a four-year-old boy with Ebstein's anomaly of the tricuspid valve with WPW syndrome. Severe tricuspid insufficiency and repeatedly occurring tachydysrhythmias soon led to cardiac decompensation and death before the intended cardiac operation. Non-invasive clinical, ECG, X-ray and ECHO examinations correlated with catheterization, electrophysiological and pathological findings. In addition to the dislocated, malformed tricuspid valve the septal cusp of which was fused with the ventricular septum the authors found another additional atrioventricular muscular connection between the lower part of the septum of the right atrium and right ventricle.

[Long-term results of radical operations on the ventricular septum with organic pulmonary hypertension]. / Dlouhodobé výsledky radikální operace komorového septa s organickou plicní hypertenzí.

From a total group of 189 children with a ventricular septal defect operated in 1978-1985 at the Cardiosurgical and Transplantation Department in Brno the authors followed up 60 patients with pulmonary hypertension. In addition to catheterization and echocardiographic examination, they made in 28 patients (46%) a preoperative pulmonary biopsy. In the majority of children before and after operation by catheterization the pulmonary tension Rp/Rs was measured and in some also pulmonary vascular resistance. During the echocardiographic examination attention was focused on the possibility to as the pulmonary tension by pulsed Doppler and continuous technique, on the detection of left-to-right shunt, pulmonary or tricuspid insufficiency. Of 60 patients 5 children (8.3%) died soon after operation, one patient died six years after operation. Long-term postoperative follow up made is possible to define more accurate indication criteria for operation as well as for pulmonary biopsy.

[Morphology of the heart conduction system]. / Morfologie srdecního prevodního systému.

Using his own experience and literary research, the author gives an outline of the morphology of the conduction systems of normal children's and adult hearts, including its blood supply.
