[Ventricular fibrillation as a symptom of prosthetic valve dysfunction that was caused by thrombosis on mitral valve. Surgery or thrombolytic treatment?].

We discuss the case of 49 years old woman with recurrent thrombosis of prosthetic mitral valve with ventricular fibrillation as the complication. For the first time thrombotic prosthetic valve Carbo Medics 33 had been removed and the new valve--Medtronic Hall 31 mm was implanted in the mitral position. After diagnosis of the repeated thrombosis on the replaced prosthetic valve, the patient refused the subsequent operation. The fully effective thrombolytic therapy was then performed. The patient was discharged from the Department and was asymptomatic 4 month follow-up.

[Activitrax--a pacemaker with a regulated rhythm rate].

In 10 patients: 7--with the complete atrioventricular block and 3 with the sick sinus syndrome the rate responsive activity sensing pacemaker--Activitrax was implanted. Significant increase of rheographically measured cardiac output in a course of rate responsive pacing in comparison with on demand constant frequency rate stimulation was stated during treadmill exercise tests performed 6 and 12 weeks after a pulse generator implantation.

Experimental method of producing total cerebral ischaemia in dogs.

Experimental method of producing total cerebral ischaemia in dogs. Acta Physiol. Pol., 1977, 28 (6): 585-588. It is very difficult to produce complete cerebral ischaemia in dogs in view of very abudant anastomoses between branches of carotid and vertebral arteries and muscle arteries. The methods applied for this purpose are technnically difficult and lead frequently to spinal cord injury or major metabolic distrubances in the whole organism. The reported investigations were carried out for elaboration of a method which would not have these disadvantages. Cerebral ischaemia was produced in dogs occluding the brachiocenhalic trunk and the left subclavian artery. The blood flow to the intercostal arteries and through them to the spinal artery was interrupted by means of a bypass between the aortic arch and the abdominal aorta. Isoelectric EEG line and lack of blood flow from the punctured carotid arteries were the criteria of complete ischaemia.
