BACKGROUND The endothelium of the internal mammary artery produces nitric oxide in greater quantity than other vessels employed in revascularization of the ischemic myocardium. The aim of this study was to measure the concentration of stable metabolite (nitrite) of the endothelium-derived nitric oxide in the venous drainage (anterior interventricular vein)(More)
Authors report an analysis of 101 patients' perioperative data in the view of myocardial necrosis development. Perioperative myocardial infarction is defined as simultaneous detection of new Q wave, and myocardial specific enzyme release with concomitant, transient pump failure. They conclude by the data of patients operated upon, that the quoted criteria(More)
BACKGROUND According to previous studies, aortic diameter alone seems to be insufficient to predict the event of aortic dissection in Marfan syndrome (MFS). Determining the optimal schedule for preventive aortic root replacement (ARR) aortic growth rate is of importance, as well as family history, however, none of them appear to be decisive. Thus, the aim(More)
The starting point, in Marfan syndrome (MFS) appears to be the mutation of fibrillin-1 gene whose deconstructed protein product cannot bind transforming growth factor beta (TGF-b), leading to an increased TGF-b tissue level. The aim of this review is to review the already known features of the cellular signal transduction downstream to TGF-b and its impact(More)
Authors report on the revascularization resulted by noninvasive and invasive interferences carried out 6-9 months after surgery and on the improvement of functional status of 56 postinfarction patients with recurrent angina pectoris. They conclude that recoronarography performed in 12 patients revealed diminished patency rate as compared to the estimated(More)
Authors report their experiences with arterial revascularization of the heart using the internal mammary artery (IMA). A method of intraoperative measurement of the free cut end and the effective graft flow of the IMA after meticulous anatomical dissection is described. Free cut end IMA flow was measured both at systemic and extracorporeal pump perfusion(More)

Objective: This study was undertaken to determine the extent of endothelium derived nitric oxide (EDNO) production of the internal mammary artery (IMA) bypass graft and of the native coronary circulation by measuring its stable metabolite (NO2: nitrite) in different sampling sites: internal mammary free cut end ̄ow, in the coronary sinus prior and after(More)
Clinical data (symptoms, diagnostic tools, surgical and histological findings, postoperative course and present status) of 26 patients with cardiac myxomas were reviewed. All myxomas were of left atrial localization. The diagnosis was confirmed by cardiac catheterization and angiography (until late seventies) and echocardiography. The delay between(More)
Out of 318 aortic valve replacements performed between July 1, 1984 and June 30, 1989, aneurysm of the ascending aorta was found in 17 cases. In 7 of these cases employment of conduit was required due to the dimension of the aneurysm. In 5 cases they performed Bentall procedure: aortic valve replacement combined with conduit of the ascending aorta with the(More)
The possible protective effect of endocavital cooling with a balloon left ventricular vent was studied by post cross clamp time rhythm, ECG, DC shock need, dynamics of temperature changes in the interventricular septum, and positive inotropic support requirement in 60 extracorporeal operations (18 aortic valve replacement, 26 aortocoronary bypass and 16(More)
