[Altered Z-disks of myofibrils in the cardiomyocytes from patients with Ebstein's anomaly].

Unlabelled: The aim of the study was to examine the peculiarities of the changes in Z-bands of myofibrils in the cardiomyocytes from patients with Ebstein's anomaly.

Material And Methods: Electron microscopy assay of intraoperative biopsies of the right heart chambers in 41 patients aged from 9 months to 57 years was performed.

Results: Some patients exhibited Z-disk alterations of two types in individual cardiomyocytes, namely: local symmetrical bead-like expansions of Z-disks or longitudinal deposits of Z-material of different lengths along the myofibrils.

Size of left cardiac chambers correlates with cerebral microembolic load in open heart operations.

Background. Microemboli are a widely recognized etiological factor of cerebral complications in cardiac surgery patients. The present study was aimed to determine if size of left cardiac chambers relates to cerebral microembolic load in open heart operations.

Asymmetric cerebral embolic load and postoperative cognitive dysfunction in cardiac surgery.

Background: The aim of the study was to determine the effects of asymmetric cerebral embolic load on cognitive functions.

Methods: Thirty-six open heart surgery (OH) and 26 coronary artery bypass grafting (CABG) patients were evaluated by neuropsychological and transcranial Doppler tests.

Results: OH was associated with a significantly larger microembolic load in comparison to CABG.

Neural correlates of cognitive dysfunction after cardiac surgery.

Patients who underwent cardiac surgery and their relatives often complain on postoperative memory impairment. Most prospective neuropsychological studies also found postoperative cognitive decline early after surgery. Nevertheless, recently several reports questioned the existence of long-term brain alterations in these patient cohorts.

[Effect of aortic clamping on hemodynamics at reconstruction of the thoracoabdominal aorta].

This paper describes an experience with monitoring and computerized follow up of the hemodynamic status in 60 patients at and right after reconstruction of the thoracoabdominal aorta. In addition to the routine control, measurements were made of the pressure in the large vessels and cavities of the heart, duration of each heart contraction and CI. The following parameters were computed automatically: the status of the ventricles for each heart contraction, resistance of the greater end pulmonary circulation, elasticity of the arterial, venous, pulmonary arterial and pulmonary venous reservoirs, also for each cardiac cycle.

Lymphedema of the extremities: prospects of microsurgical treatment.

Presented herein is an experience with the treatment of 60 patients with lymphedema of the extremities, who had undergone transplantation of "lymphatic flaps". The treatment success is analyzed in both free microsurgical autotransplantation of tissue complexes (52 patients) containing intact lymphatic structures and in transposition (8 patients). The authors evaluate the potential of radio-nuclide diagnostic techniques for quantification of the effectiveness of surgical treatment.

[Microsurgical transplantation of "lymph flaps"].

The review is concerned with the main historical stages in the development of "lymph flaps" transplantation. The author describes their blood supply, the topography of the constituent lymph structures, the feeding vascular pedicle, techniques of the harvesting, revascularization and restoration of lymph drainage. The review is intended for familiarization of a wide circle of physicians with the current strategy of microsurgical treatment of extremity lymphedema.

Results of hospital bypass angiography in patients with coronary artery disease undergoing arterial and vein myocardial revascularization.

This paper analyzes the results of 94 coronary artery bypass grafts accomplished at the Department of Surgical Treatment of Concomitant Lesions of Coronary and Peripheral Arteries, A.N. Bakulev SCCVS, RAMS, in patients with coronary artery disease (CAD) provided control hospital bypass angiography over the period 1998 to 2002.

[Abnormal branching of the left coronary artery from the pulmonary artery].

13 hearts with the above congenital disturbance are studied. The disturbance of the space orientation of the anterior and posterior interventricular septa is found. The aortal and pulmonary valves are found to be oriented at an angle to each other, and the route of the left coronary artery is changed.
