[Pulmonary and diaphragmatic mechanics and respiratory movements in patients with heart valve disease].

Pulmonary ventilation, and pulmonary and diaphragmatic mechanics were examined in 41 patients with valvular defects and circulatory insufficiency of varying severity. The hemodynamic function of the thoraco-abdominal pump mechanism was shown to be disrupted in valvular disease, resulting in reduced capacity of "sucking" blood towards the heart, and increased capacity of "pumping" it on a compensatory basis. It is concluded that insufficiency of the thoraco-abdominal pumping mechanism can contribute to the progress of hemodynamic disorders and the development of associated respiratory and circulatory disturbances.

[Can present-day noninvasive cardiological diagnosis replace heart catheterization in acquired heart valve diseases?].

The available noninvasive cardiac investigational methods allow an accurate diagnosis in patients with acquired valvular defects and, in most cases, a decision on timing of surgery. Retrospective studies showed that cardiac catheterizations in 45 of 111 consecutively investigated patients were superfluous. Thus, in 40% of these patients noninvasive methods were sufficient for a reliable decision on whether to proceed with surgery or conservative measures and for a satisfactory objective assessment of preoperative haemodynamics and morphology. Invasive methods should only be used when there are insufficient or discrepant noninvasive findings or when accompanying coronary heart disease must be excluded.

[Characteristics of pregnancy and delivery in women with rheumatic heart valve disease].

UNLABELLED: During a six years period, we followed 55 pregnant women having rhumatismal valvulopathy. The prevalence of the association rhumatismal valvulopathy and pregnancy is about 44%. The RM represents the most frequent rhumatismal valvulopathy that is about 43.5%. Among our patients 5 represented a cardiac decompensation (9%). Our study resulted in:cesarean section rate: 23.6% 1 maternal death neonatal death rate 36%. 14.5% prematurity rate 9% hypotrophy rate. CONCLUSION: The pregnancy of patients bearing the rhumatismal valvulopathy represents a high risk situation. The maternal death during and after pregnancy exist and can reach an average of 1%.

[Hemodynamic side effects of an ionic and a nonionic roentgen contrast medium in patients with heart valve diseases and pulmonary hypertension].

The purpose of this study was to compare the hemodynamic side effects of an ionic and a nonionic contrast medium intra-individually. 20 patients with valvular heart disease (NYHA III-IV) and pulmonary hypertension (PPAsyst greater than or equal to 40 mm Hg) received injections of 40 ml iopamidol (0.8 osmol/kg) and 40 ml amidotrizoate (2.1 osmol/kg) into the right atrium. Heart rate and cardiac output, as well as right atrial, pulmonary-artery, pulmonary-capillary, and aortic pressures were measured. Peripheral and pulmonary vascular resistance and stroke volume were calculated. Right atrial pressure increased more after amidotrizoate (p less than 0.001). Pulmonary artery pressure was elevated with both contrast media to the same extent. An increase in aortic pressure was seen after iopamidol, while a decrease occurred after amidotrizoate (p less than 0.01). Amidotrizoate caused a more marked increase in heart rate (p less than 0.001) and cardiac output (p less than 0.001). Stroke volume was increased with both contrast media. Pulmonary vascular resistance decreased after amidotrizoate as well as after iopamidol, but systemic vasodilatation was more pronounced following injection of amidotrizoate (p less than 0.001). In general, iopamidol caused less hemodynamic side effects than amidotrizoate. Thus, nonionic low osmolality contrast media provide decreased risks in patients with valvular heart disease and elevated pulmonary artery pressures undergoing angiocardiography and intravenous digital subtraction angiocardiography.

[Anesthesia and post-operative intensive care in 55 patients with heart valve disease at high surgical risk. Technics and analysis of results].

Anaesthetic and Postoperative intensive Care techniques employed in 55 successive high risk surgical patients with valvular heart disease are discussed. Whereas an anaesthetic standard procedure is well established. Postoperative cardio-respiratory therapy in ICU is singularly decided on the basis of the physiological signs measured. The cardio-respiratory monitoring system at work is explained in details and a special bedside estimation of pulmonary circulation morphology is outlined. In our opinion an individualized treatment causes the post-operative recovery time to be sharply reduced. The myocardial protection during ischemic cardiac arrest has a crucial influence on the early mortality: among patients treated with Breitschneider II cardioplegic solution the early mortality is 10,8% at the lower level of the mortality range exhibited by other outstanding surgical teams.
