Beating heart coronary surgery supported by an axial blood flow pump

摘要: Abstract Background . We have previously presented a method for performing coronary artery bypass graft operation on the beating heart without cardiopulmonary (CPB). This has now been explored. Method Thirty-two patients were prospectively randomized. The study group was operated using an axial blood flow pump (Hemopump; HP) as circulatory support. Operations performed heart. control CPB, aortic cross-clamping, and cardioplegic arrest. Results All went through procedure major complications, discharged from hospital. No statistical differences observed between groups time support (HP, 60.5 minutes; 70.5 minutes) or total operating 178 162 minutes). number of grafts greater in CPB 1.8; range, 1 to 3; 2.5; 4; p = 0.03). Statistical found intraoperative bleeding (HP mean, 312 mL; 582 0.0003) myocardial trauma measured by postoperative troponin-T values 0.23 μg/L; 1.17 0.004). Conclusions Hemopump-supported shown be safe feasible with potential benefits reduced operative damage prolonging time.
