    Streszczenie angielskie: Background. Coronary artery by-pass grafting (CABG) without cardiopulmonary by-pass (CPB) but with the use of a new generation of stabilisers has been recently shown to be a safe and reproducible procedure, and is increasingly used in cardiac surgery. Aim. To compare early results of CABG performed with or without CPB. Methods. 150 consecutive patients who underwent VABG in 1999 were recruited to the study. Peri-operative and early in-hospital post-operative data were analsed in three groups of patients who underwent different strategies of CABG. One group had CABG with CPB whereas the two other groups underwent "off-pump" CABG (OPCAB) with different post-operataive protocols. All groups were comparable with regard to the peri-operative risk factors. The early post-operative period in the intensive care unit was analysed including ventilation time (IPPV), inotropic agents usage, blood and fluid transfusions, urine output, overall fluid balance, drainage, and various laboratory results. Results. Compared with patients who underwent standard CABG, the OPCAB patients had higher haemoglobin and platelet levels, lower transfusion rate, lower inotropic drug usage and shorter duration of hhospitalisation. Different post-operative strategies in the OPCAB patients significantly influenced the IPPV time, urine output, transfusion rate, duration of hospitalisation and the frequency of post-operative atrial fibrillation. Conclusions. Patients selcted for OPCAB were characterised by a similar risk profile to that of patients who undergo CBG with CPB. However, the former group had shorter duration...

    Streszczenie angielskie: Background. Increasing data suggest that stentless biological aortic valves may be more durable and cause better haemodynamic imporvement than convetional biological aortic valves. Aim. To compare the haemodynamic effects of stentless versus conventonal stented bioprostheses of aortic valve. Methods. The study gorup consisted of 28 patients who were selected from 100 consecutive patients who underwent aortic valve replacement in 1996 and 1997. Fourteen patiens (7 males, mean age 68 ń 5 years) received a stentless bioprosthesis (Freestyle wheras in the remaining fourteen (7 males, mean agae 73 ń 6 years) a conventional aortic valve (mosaic) was implanted. Both groups were matched for age, gender and the size of the implanted valve. Because of the same technology of valve fixation and anticalcification, the differences between the two types of valves may be only due to the presence of stent. Haemodynamic effect were assessed using echocardiography performed just after, 6 months and 12 months afte surgery. Flow velocities across the valve and the left ventricular outflow tract, fractional chortening and left ventricular mass were measured. Results. The maximal flow velocity across the valve was significantly lower in the stentless group compared with the patients with stented valve. Also, the mean transvalvular gradient significantly decreased in the former group of patients. The regresson of the left ventricular mass was similar in both groups. Left ventricular ejection fraction increased in both groups, however, the improvement was significantly greater in the patients with a seentless valve. Conclusions. Haemodynamic effects of stentless prosthetic aortic valves are better than those of conventional stented bioprosthesis.
