[The animal experiments and clinical trial of impeller pump used as left ventricular or biventricular assist device].

The authors' impeller pump as a left ventricular or biventricular assist device was evaluated in animal experiments and clinical trial. Three calves survived over 6 weeks in left ventricular assist experiments and neither blood damage nor organ dysfunction of the animals was detected. In clinical trial, the pump supported both the greater and lesser circulation of a 6-year-old child with trilogy of Fallot and low output syndrome after open heart surgery. In 43 hours the pump worked properly. The pump weighing 240 g can perform either in pulsatile or in nonpulsatile mode. In pulsatile pumping, the impeller changes its rotating speed periodically by introducing a square wave form voltage into the motor coil.

Pregnancy after high therapeutic doses of iodine-131 in differentiated thyroid cancer: potential risks and recommendations.

Seventy female patients who had been treated with high doses of iodine-131 for differentiated thyroid cancer (DTC) and who had a subsequent pregnancy were evaluated. The total 131I dose ranged from 1.85 to 16.55 GBq (mean +/- SD = 4.39 +/- 25.20 GBq). Age at first therapy ranged from 15 to 36 years (mean +/- SD = 24.3 +/- 5.0 years) and the interval from 131I therapy to pregnancy varied from 2 to 10 years (mean +/- SD = 5.3 +/- 2.8 years). The estimated radiation dose to the gonads ranged from 10 to 63 cGy (mean +/- SD = 24.0 +/- 13.5 cGy). All patients were treated with L-thyroxine at doses capable of suppressing thyroid-stimulating hormone. Seventy-three children were followed-up and seven pregnancies are still in progress. One child was affected by Fallot's trilogy and three had a low birth weight through with subsequent normal growth; the others were healthy with subsequent normal growth. No newborn with clinical or biochemical thyroid dysfunctions was found. Two spontaneous abortions during the second month of pregnancy were recorded. One of two patients in question subsequently had two healthy children. On the basis of these data, previous administration of high 131I doses does not appear to be a valid reason for dissuading young female DTC patients from considering pregnancy. However, patients should be advised to avoid pregnancy after 131I administration for a period sufficient to ensure complete elimination of the radionuclide and to permit confirmation of complete disease remission, i.e. at least 1 year in our opinion.

[False positive of the exercise test and right auricular hypertrophy].

Seldom mentioned as a possible etiology of false positive stress tests (ST), the right atrial hypertrophy (RAH) may cause electrocardiographic aspects evocative of myocardial ischemia in the lower areas. The retrospective study concerns STs in 4 patients, staying in a cardiac rehabilitation center, following (D14) surgery for isolated type II IAC, Fallot's trilogy (n = 1), or dual valvular disease (tricuspid insufficiency and mitral stenosis, n = 1), and presenting all on basal ECG a RAH (group I). These STs are compared to that of a reference group operated (D14) from a IAC type II (isolated n = 3, associated to RVPA n = 1), but without signs of RAH on the rest ECG (group II). All other possible causes of electrically positive STs were eliminated from this study. In patients with RAH, the stress test is positive in the lower area (ST = -1.27 +/- 0.25 mm). In four other patients without HAD, the STest is negative in 3 cases and uncertain in one. These results do not seem to be linked to pre-operative hemodynamic data, nor to sonocardiographic data. Atrial repolarization alone seems to be the cause of these ECG alterations during stress, as demonstrated, in one patient, by sudden variations of the ST segment during a change from an atrial rhythm (AR) (with retrograde atrial depolarization) to a sinus rhythm (SR). These observations suggest the role of atrial repolarization in the origin of false positive stress tests in patients with RAH.

[Surgical treatment of atrial septal defects and associated congenital heart diseases].

The results of radical correction of interatrial septum defects and heart diseases associated with it were analyzed after treatment of 502 patients at the age from 5 to 48 years. In most cases (58.4%) the patients were adults. The isolated defect of the interatrial septum was diagnosed in 377 patients. Correction of the defect was performed in 82 patients (16.3%) under mild hypothermia and 420 patients (83.6%) were operated upon under conditions of artificial circulation. General lethality was 7.7%.
