The comprehensive assessment of frailty is an additional tool to evaluate elderly patients adequately before cardiac surgical interventions. The Frailty score combines characteristics of the Fried criteria [1], of patient phenotype, of his physical performance and laboratory results. Further analysis on a larger patient population is warranted. A combination of the new Frailty score and the traditional scoring systems may facilitate a more accurate risk scoring in elderly high-risk patients scheduled for conventional cardiac surgery or trans-catheter aortic valve replacement.

Transapical minimally invasive aortic valve implantation is feasible using an off-pump technique. Good results have been achieved in the initial 50 patients, especially when considering the overall high-risk profile of these patients.

Objective: Aortic surgical procedures requiring hypothermic circulatory arrest are associated with altered hemostasis and increased bleeding. In a randomized clinical trial, we evaluated effects of thromboelastometrically guided algorithm on transfusion requirements. Methods: Fifty-six consecutive patients (25 with acute type A dissection) undergoing aortic surgery with hypothermic circulatory arrest were enrolled in a randomized trial during a 6-month period. Patients were randomly allocated to treatment group (n ¼ 27) with thromboelastometrically guided transfusion algorithm or control group (n ¼ 29) with routine transfusion practices (clinical judgment-guided transfusion followed by transfusion according to coagulation test results). Primary end point was cumulative allogeneic blood units (red blood cells, fresh-frozen plasma, and platelets) transfused. Results: Transfusion of allogeneic blood was significantly reduced in the thromboelastometry group: median 9.0 units (interquartile range, 2.0-30.0 units) versus. 16.0 units (9.0-23.0 units, P ¼ .02). Most significant decrease was in the use of fresh-frozen plasma (3.0 units, 0-12.0 units, vs 8.0 units, 4.0-18.0 units, P ¼ .005). Postoperative blood loss (890 mL/d, 600-1250 mL/d vs 950 mL/d, 650-1400 mL/d, p ¼ 0.5) and rate of surgical re-exploration (19% vs 24%, P ¼ .7) were similar between groups. Thromboelastometrically guided algorithm significantly decreased need for massive perioperative transfusion (odds ratio, 0.45; 95% confidence interval, 0.2-0.9; P ¼ .03) in multivariable logistic regression analysis. Conclusions: Thromboelastometrically guided transfusion is associated with a decreased use of allogeneic blood units and reduced incidence of massive transfusion in patients undergoing aortic surgery with circulatory arrest.
