[Percutaneous transvascular pulmonary valvuloplasty. Early and late results].

Since the introduction into practice in may 1986 at the Institute of Cardiovascular Diagnostics we performed 45 valvuloplasties until March 1990 in 34 children (6.2 +/- 4.9 years old) and 11 adults (29.5 +/- 9.6 years) with valvular pulmonary stenosis. The invasively obtained pressure gradient at the valve diminished from 83.4 +/- 30.7 mm Hg to 35.7 +/- 19.0 mm Hg. Intraoperative complications in three patients (short term asystole, severe bradycardia, increase of right ventricular pressure to 300 mm Hg after valvuloplasty) were controlled, but demanded the end of the intervention. No significant insufficiency of pulmonary valves after valvuloplasty was seen. 18 patients were clinically investigated 14.6 +/- 9.4 months after intervention. The late results for these patients proved the method as a long term curing treatment. According to our present results pulmonary valvuloplasty is the alternative method for valve surgery especially in critical pulmonary valve stenosis in newborns.

[Persistent and patent ductus arteriosus. Different forms and sizes].

In 563 consecutive heart catheter investigations in sucklings, infants and children 109 open ducti were diagnosed. 75 children (13.3%) had a ductus arteriosus persistens (DAP) and 34 a ductus arteriosus (DAA). We were able to measure 89 ducti. Groups were formed according to the age of the children, of DAP or DAA and the intended treatment. The sizes of the ducti constitute a set of data for improving the methods for closure or newly developed transvasal methods of conservation of the ductus as an aortopulmonary shunt.

[Castaneda-de Leval's modified Fontan operation in complex cyanotic defects with subsequent percutaneous transluminal embolization of systemic pulmonary collaterals].

The case of a five year old boy with a double-inlet-left-ventricle and the aorta in 1-malposition, large VSD, ASD and pulmonary stenosis is reported, that showed after modified Fontan surgery severe effusions and a severe protein loss syndrome. Aortopulmonary collaterals were detected as the cause of this and successfully treated in several sessions by percutaneous transluminal embolization.

[A double-blind randomized comparative study of iopromide and amidotrizoate in the angiocardiography of infants and young children with congenital heart defects].

For 50 sucklings and small infants with cyanotic and acyanotic heart defects the non-ionic contrast medium Iopromide was tested against the ionic contrast medium Amidotrizoate in angiography. With consideration to the applied method the tested cardiospecific enzymes (CK MB, alpha-HBDH, lactate) as well as hematocrit, oxygen content of central venous blood, heart rate, systolic pressures in both ventricles and ECG showed no significant differences. The different end-diastolic pressures in both ventricles and the average pressure in the right atrium, however, showed the cardiotoxicity of Amidotrizoate. Conclusively the use of Iopromide is demanded for infants, small infants and sucklings.

[Clinical experiences in 210 percutaneous removal of kidney and ureteral calculi].

The introduction of percutaneous nephrolithotomy and ureterolithotomy has greatly widened the therapeutical spectrum of urolithiasis. In this paper indications and contraindications of percutaneous stone removal will be discussed as well as techniques of this procedure. 210 percutaneous stone operations were performed after an initial training period primarily using local anesthesia (neuroleptanalgesia). This operative procedure allowed stone removal in patients otherwise inoperable because of increased operation risk or of advanced age. With increasing experience the success rate has been improved, though the stage of difficulties in nephrolithotomy and ureterolithotomy has increased too. Percutaneous operation primarily in connection with extracorporal shock wave lithotripsy is the first treatment modality for patients with staghorn stones. Possible complications (bleeding, perforation, injury to neighbouring organs) and their treatment are discussed.

[The percutaneous approach to the pediatric kidney].

The percutaneous access also to the infantile kidney increasingly gains significance. It is reported on experience with 16 percutaneous interventions at the kidney in 14 children. Indication, technique and complications are demonstrated, compared with literature and discussed. The percutaneous access to the kidney allows the clarification of certain diagnostic problems, guarantees the protection of the kidney in congenital and acquired obstructions, septic renal diseases, postoperative complications. The drainage of urinomas, the dilation of stenoses of the ureter as well as nephrolitholapaxia and chemolitholysis are with certain restrictions possible also in childhood.

[Relation of the impedance cardiogram to the course of myocardial contraction].

53 patients with coronary heart disease were investigated synchronously by means of impedance and angiocardiography combined with the measurement of the pressure in the aorta and the left ventricle. In these cases relatively close correlations were found between the stroke volumes and systolic time intervals, determined by the two methods, as well as between the ejection fraction on the one hand and the parameter dz/dt max on the other. The pressures, measured invasively, do not correlate significantly with the impedance cardiography parameters. With help of the relations found it is possible to coordinate the changes of the thoracic impedance curve depending on the heart action with the various phases of the left-ventricular volume change.
