Introduction: Endotoxemia developing during cardiosurgery as elevated endotoxin concentrations in patient’s serum may prevail over 24 h after operation. A major reason is thought to be increased gut permeability resulting in endotoxin and bacterial leakage. In this study we aimed to measure endotoxin levels on samples obtained during and after(More)
Mediastinitis is a well-known complication of open heart surgery. Abscess as late complication, presenting years after heart surgery, is adegnotical. Transthoracic needle biopsies of lung parenchyma guided by computer tomography are widely accepted. The puncture of periaortic masses is not routinely performed. We report the case of an encapsulated(More)
INTRODUCTION There has been a growing interest in off-pump coronary artery bypass (OPCAB) grafting in recent years. Beating-heart surgery is believed to be less invasive as it allows the side effects of extracorporeal circulation to be avoided. THE AIM OF THE STUDY The aim of the study was to compare blood product transfusion rates between two groups of(More)
BACKGROUND Milrinone is a selective inhibitor of the cAMP-specific phosphodiesterase III isoenzyme in myocardium and vascular smooth muscle. Milrinone administration following heart transplantation is routine practice. The purpose of this study was to evaluate the influence of milrinone therapy on splanchnic perfusion following heart transplantation. (More)
INTRODUCTION Monitoring the central nervous system during aortic dissection repair may improve the understanding of the intraoperative changes related to its bioactivity. AIM The aim of the study was to evaluate the influence of deep hypothermia on intraoperative brain bioactivity measured by the compressed spectral array (CSA) method and to assess the(More)
We present a case of the native valve used to complete closure of a ruptured aneurysm of the sinus of Valsalva. Aneurysm of the sinus of Valsalva is rare and a non-coronary artery is affected in only 20% of cases. To close the rupture, we decided to use a non-coronary leaflet in a young patient with moderate aortic stenosis and fibrosis of the leaflets. In(More)
Infant of diabetic mothers (IDM) may be in circulatory failure due to hyperthrophic cardiomyopathy (HCM). HCM is thought to be related to high insulin levels in fetus as a consequence of poor controlled maternal diabetes.Design: To analyze the relationship between morphological heart parameters and cardiac function assessed during echocardiography(More)
A case of a 49-year-old female with acute coronary syndrome is presented. The patient underwent coronary angioplasty with stent implantation. Due to the recurrence of pain and dyspnea a repeated coronary angiography was performed 3 hours later which confirmed good result of angioplasty. For the next 48 hours a local compression on both femoral arteries was(More)
