Inability to wean a patient from the cardiopulmonary bypass after open heart procedure is reality of the clinical practice. The only realistic chance for these patients is some form of mechanical circulatory support. Over the period from November 1988 to November 1993, in 17 patients the roller-pump mechanical assist device was inserted, i.e. 0.47% of 3589 patients were operated on during this period. Thirteen patients required mechanical circulatory support immediately after surgical procedure due to inability to wean them from cardiopulmonary bypass. In three patients the roller-pump was inserted preoperatively (percutaneous insertion), and in one patient mechanical circulatory support was started six hours after the procedure for sudden cardiac deterioration. Partial and temporary "bypass" of the damaged left ventricular function is achieved by insertion of inflow cannula into the left atrium, and outflow cannula into the ascending aorta. Depending on the inflow cannula size and volume load, we were able to achieve blood flow of 3.5 to 5 liters/minute. Using this system we were able to improve the left ventricular function in eight patients (47%), and five patients were discharged from hospital (29.4%). The roller-pump mechanical circulatory support proved to be efficient, reliable, easy to monitor and operate. Overall results are comparable to the published data as well as to other types of more versatile and costly devices for mechanical circulatory support.
心脏直视手术后患者无法脱离体外循环是临床实践中的现实情况。对于这些患者而言，唯一现实的机会是某种形式的机械循环支持。在1988年11月至1993年11月期间，17例患者植入了滚压泵机械辅助装置，即在这期间接受手术的3589例患者中占0.47%。13例患者因无法脱离体外循环，在手术后立即需要机械循环支持。3例患者在术前（经皮插入）植入了滚压泵，1例患者在手术后6小时因心脏突然恶化开始机械循环支持。通过将流入插管插入左心房，流出插管插入升主动脉，实现对受损左心室功能的部分和临时“旁路”。根据流入插管的大小和容量负荷，我们能够实现3.5至5升/分钟的血流量。使用该系统，我们使8例患者（47%）的左心室功能得到改善，5例患者出院（29.4%）。滚压泵机械循环支持被证明是有效、可靠、易于监测和操作的。总体结果与已发表的数据以及其他类型更通用且成本更高的机械循环支持装置相当。
