[Long-term prognosis of patients with chronic post-infarct aneurysms. II. Comparison of patients treated conservatively and surgically].

UNLABELLED: Survival rates were determined for a group of 136 patients in whom left ventricular aneurysm was determined by angiography. They were treated medically (99 patients) or surgically (37 patients). Congestive heart failure was predominant in all patients. The two groups did not differ in regard to clinical and haemodynamic data except for a more extensive coronary artery disease in the surgical group. Survival rates at the 5, 7 and 9 years were 62.5%, 52.5% and 37.5% in the medicaly treated group and 50%, 40% and 32.5% in the surgical group. Functional improvement at least one Functional Class NYHA was present in 75% patients postoperatively, and in 27% of patients treated medically. CONCLUSION: In patients with left ventricular aneurysm with predominant congestive heart failure surgical treatment improved quality of life but did not increase long-term survival.

[Surgical treatment of postinfarction heart aneurysms and akinesias].

The paper deals with the problem of surgical treatment of cardiac aneurysms and akinesias from the aspect of indication of surgical tactics and technique, risk factors and achieved results. The group of 117 patients is divided into 74 patients operated in 1970-1982 and 43 patients operated in 1983-1987 when already medium hyperthermia was used permanently, similarly as cold cardioplegia, complete haemodilution, pulsed extracorporeal circulation and relieving drainage of the left ventricle via the pulmonary artery. The reduction of early mortality from 24.3% to 4.7% provides clear evidence of the advantages of this procedure. The authors draw attention to differences in indications of surgical treatment between classical aneurysms and akinesians and to the importance of revascularization operations performed nowadays, using aortocoronary bypasses.

[Surgical treatment of tumors of the heart].

The authors present an account on four cases of cardiac myxoma and two cases of a secondary malignant tumour. Despite the low incidence of cardiac tumours this disease must be taken into consideration. The diagnosis was established by echocardiography and angiography. Two-dimensional echocardiography is, however, often sufficient. Early surgical treatment has very favourable results in bening tumours. The prognosis of patients with malignant tumours is very poor and experience with treatment is scanty.

[Stress perfusion tomography of the myocardium using the 201 thallium isotope in cardiac surgery--evaluation of initial results].

Initial results of evaluation of scintigraphic examinations by means of the isotope 201thallium indicate the importance of this method in cardiosurgery, in particular in the postoperative evaluation of the effect of bypass operations. In patients with an objective improvement on the postoperative scintigrams also subjective improvement of the condition was recorded.

[Results of surgical treatment of pulmonary carcinoma in patients over 60 years of age].

The authors submit an analysis of patients operated in 1972-1982 at the First Surgical Clinic, Faculty of General Medicine, Charles University Prague. The group of patients was divided into those under 65 years and those above this age. The effect of the patients' age on the postoperative course was investigated, the survival of the two groups was compared, the causes of early postoperative deaths, the extent of the disease and histological type of tumour were evaluated. In was revealed that the risk of early postoperative death within one month is greater in patients above 65 years where it is 19.6%, as compared with 11.3% in the younger group. The risk increases in particular in patients above 70 years where it is as high as 26%. There is no fundamental difference in the causes of death between the two groups. The highest percentage of operated patients dies from embolism (40% and 42% in the patients above 65 years), the second place is held by inflammatory pulmonary complications which are somewhat more frequent in patients of the younger age group (24% as compared with 15% in the older patients). The survival curves of patients who had a radical operation in stage I and II of the neoplastic disease are almost identical and there is no significant difference in the survival of the two groups. In the group under 65 years 30% survive five years, in the older group 25%. The ratio of differentiated types of lung cancer, i.e. adenocarcinoma and epidermoid carcinoma is equal in both groups, contrary to small-cell carcinoma which was recorded in 6% in the older patients, as compared with 15% in the younger ones.

[Cardiac decompression using pulmonary artery drainage during operations with extracorporeal circulation].

The authors report their experience with the application of decompression of the left ventricle of the heart by means or active suction from pulmonary artery. This way of heart drainage has been so far used in 53 patients, who were operated in extracorporal circulation. The drainage of pulmonary artery proved to be completely successful. It enabled a sufficient decompression of the left heart and prevented most complications which may occur if a direct drainage of the left ventricle of the heart is applied.
