Aortic valve replacement with the minimal extracorporeal circulation (Jostra MECC System) versus standard cardiopulmonary bypass: A randomized prospective trial

Abstract: The MECC System is safe and allows aortic valve replacement under the most favorable conditions. The system is more biocompatible than standard cardiopulmonary bypass and provides a good postoperative biologic profile and good clinical results, particularly for high-risk patients.

“…Similar to OPCABG, in initial clinical experience MECC has proved to be safe, feasible, and superior to standard CPB in terms of postoperative complications. 4 Although a number of studies compare valve and coronary surgery with the use of MECC versus standard CPB, 5 no data are available on the outcomes of coronary revascularization with OPCABG versus MECC. We performed a direct comparison of the biocompatibility, early results, and 1-year outcome of myocardial revascularization with the use of either OPCABG or MECC.…”

“…The improved biocompatibility of MECC is of special advantage in high risk patients (age over 65, renal and pulmonary dysfunction). The use of a minimal ECC involves a learning curve, however (82). More recently, TAVI or transcatheter aortic valve implantation, either through an artery or through the cardiac apex has been developed as third alternative.…”

“…Mechanisms inflicting renal damage are non-pulsatile perfusion, renal hypoperfusion, hypothermia, and increased levels of circulating catecholamines, cytokines, enzymes, free radicals and free hemoglobin (80). Keeping the cross-clamp time as short as possible or installing a minimal ECC could be helpful (81,82). In spite of increasing age and co-morbid conditions in patients referred for AVR, the increase in hospital complications seemed to be limited to non-cardiac complications, which have a lower fatality rate than cardiovascular complications (83).…”
