long-term results Aortic valve surgery in octogenarians: predictive factors for operative and This information is current as of April 2, 2007http://ejcts.ctsnetjournals.org/cgi/content/full/31/4/600 located on the World Wide Web at:The online version of this article, along with updated information and services, is AbstractObjective: To assess factors influencing operative and long-term outcome in octogenarians undergoing aortic valve surgery (AVR). Methods: Records of 220 consecutive octogenarians having AVR between 1992 and 2004 were reviewed, and follow-up obtained (99% complete). Of the group (mean age: 82.8 years; 174 females), 142 patients (65%) were in New York Heart Association (NYHA) class III-IV, 22 (10%) had previous myocardial infarction, 11 (5%) had previous coronary artery bypass grafting (CABG), and 8 (4%) had percutaneous aortic valvuloplasty. There were 44 urgent procedures (20%), and additional CABG was performed in 58 patients (26%). Results: Operative mortality was 13% (9% for AVR, 24% for AVR + CABG). Among the 29 patients who died, 14 (48%) were operated on urgently (32% mortality for urgent procedures). Causes of hospital death were respiratory insufficiency or infection in 16 patients (16/29 = 55%), myocardial infarction in 8 (28%), stroke in 2 (7%), sepsis in 2 (7%), and renal failure in 1 (3%). Significant postoperative complications were atrial fibrillation in 48 patients (22%), respiratory insufficiency in 46 (21%), permanent atrio-ventricular bloc in 12 (5%), myocardial infarction in 10 (5%), hemodialysis in 4 (2%), and stroke in 4 (2%). Mean hospital and intensive care unit (ICU) stays were 17.6 AE 5.2 and 6.9 AE 3.4 days, respectively. Multivariate predictors ( p < 0.05) of hospital death were urgent procedure, associated CABG, NYHA class IV, and percutaneous aortic valvuloplasty. Age, associated CABG, and urgent procedure were predictors of prolonged ICU stay. Mean follow-up was 58.2 months and actuarial 5-year survival was 73.2 AE 6.9%. Age, preoperative myocardial infarction, urgent procedure, and duration of ICU stay were independent predictors of late death. Among 130 patients alive at follow-up, 91% were angina free and 81% in class I-II. Conclusions: AVR in octogenarians can be performed with acceptable mortality, although significant morbidity. These results stress the importance of early operation on elderly patients with aortic valve disease, avoiding urgent procedures. Associated coronary artery disease is a harbinger of poor operative outcome. Long-term survival and functional recovery are excellent. #

Cardiac operations are successful in most octogenarians with increased hospital mortality, and longer hospital stay. Long-term survival and quality of life are good.

Aortic valve replacement in octogenarians can be performed with acceptable mortality. These results stress the importance of early operation on elderly patients with aortic valve disease. Both long-term survival and functional recovery are excellent.

Intraoperative blood salvage devices allowing a reinfusion of red blood cells (RBCs) after processing of shed blood and stagnant blood in the mediastinal cavity are more and more used to reduce homologous blood requirements in cardiac surgery with cardiopulmonary bypass (CPB). As the proinflammatory activity of the shed blood also contributes to morbidity during CPB, we conducted a prospective study in order to examine the quality of autologous blood before and after processing with five different devices [BRAT2, Sequestra, Compact Advanced, Cell Saver 5 (CS5), Continuous Autologous Transfusion System (CATS)]. All systems resulted in an excellent haemoconcentration, ranging from 53.7% (Compact) to 68.9% (CATS). The concentrations and elimination rates of several inflammatory markers [IL-1beta, IL-2, IL-8, TNFalpha, myeloperoxidase (MPO), elastase] were examined. Except for the Sequestra, an important increase in concentration of IL-1beta (between 30% and 220%) has been observed after processing with each device. In contrast, the attenuation rate of IL-6 and TNFalpha (95%) was optimal for all investigated blood salvages systems. Regarding IL-8, only the CATS and CS5 systems were able to attenuate this biological parameter with an excellent efficacy. The rate of attenuation in MPO and elastase, as markers of leukocyte activation, was higher than 80% for all devices. In conclusion, the different RBC washing systems tested in this study resulted in a significant attenuation of the inflammatory response. Increased levels of IL-1beta after processing remained, however, unclear. According to the type of protocol, based on inlet haematocrit, fill and wash speeds, and wash volumes, small variations in reducing the inflammatory response have been observed from one device to another.
