We underwent pulmonary valve replacement using the right ventricule pulmonary artery bypass without cardiopulmonary bypass. This right heart bypass was consisted of the vascular graft and the polystyrene tube. The vascular graft was anastomosed to the main pulmonary artery and the polystyrene tube was inserted into the free wall of the right ventricle. These were connected with a cannulating magnetic flow probe. After the bypass was established, the pulmonary artery was clamped and divided. The pulmonary valves were excised and the pulmonary valve replacement was undergone with a pulmonary valve homograft. Hemodynamics during the pulmonary valve replacement was stable and the postoperative course was uneventful. One month later, the cardiac catheterization and cineangiography showed that the implanted homograft was effective sufficiently. We concluded that this right heart bypass was useful for the pulmonary valve replacement.
我们在非体外循环下采用右心室肺动脉转流术进行了肺动脉瓣置换。这种右心转流由血管移植物和聚苯乙烯管组成。血管移植物与主肺动脉吻合，聚苯乙烯管插入右心室游离壁。它们通过一个插管式磁流量探头相连。转流建立后，肺动脉被夹闭并切断。切除肺动脉瓣，并用同种异体肺动脉瓣进行肺动脉瓣置换。肺动脉瓣置换过程中的血流动力学稳定，术后过程顺利。1个月后，心导管检查和心血管造影显示植入的同种异体瓣膜功能充分有效。我们得出结论，这种右心转流术对肺动脉瓣置换有用。
