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)
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)
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)
Authors measured the concentration of stable metabolite (NO2: nitrite) of EDNO (endothelium derived nitric oxide) in the internal mammary artery (IMA) bypass graft with the help of a previously reported method (measurement of effective blood flow capacity of the IMA graft in the coronary sinus). Nitrite level in the systemic circulation prior to(More)
Authors present a case report about the surgical management of a genetically predisposed ischemic heart disease occurred in young age with rare anatomical variation causing unstable angina pectoris. Besides the description the type of surgery, emphasis is made on the importance of whole scale cardiological investigations and--as in the described case--on(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)
Authors report their experiences with coronary artery bypass surgery without cardiopulmonary bypass. Between January 1993 and June 1995, 151 patients were operated upon by the same surgeon for ischaemic heart disease (IHD); 7 were of them without extracorporeal circulation (ECC). Patients were selected for the procedure on the following criteria: (1)(More)
Authors present the case report of a young man with advanced coronary artery disease of the left main trunk, and the large tributaries of the left coronary system, leading to sudden onset of many ventricular fibrillation, associated with unconsciousness requiring several reanimation. The condition was treated with coronary artery surgery with the use of(More)
Authors report the type of revascularization, the result of noninvasive and invasive investigations carried out 6-9 months after surgery, improvement of functional status of 56 postinfarction patients with recurrent angina pectoris. They conclude, that recoronarography performed in 12 patients revealed diminished patency rate compared to the estimated(More)
