Extracardiac valved conduits are routinely employed in the correction of complex congenital heart lesions. Compression of a conduit and/or of the heart may present serious operative and postoperative complications. We believe its occurrence can be minimized and hemodynamic results improved by adhering to simple surgical techniques. It is important to select a conduit which will produce minimal resistance to flow. Partial or subtotal thymectomy may increase the mediastinal space to accommodate the conduit. The conduit should be cut into the appropriate shape and should be placed in such a way that it does not cross the midline. Finally, the posterior pericardium may be opened to allow the heart to move posteriorly and to rotate to the left, thus moving the conduit away from the sternum.
心外带瓣管道通常用于复杂先天性心脏病变的矫治。管道和/或心脏受压可能会出现严重的手术及术后并发症。我们认为，通过遵循简单的手术技巧，可将其发生率降至最低并改善血流动力学结果。选择对血流阻力最小的管道很重要。部分或次全胸腺切除术可增加纵隔空间以容纳管道。应将管道剪成合适的形状，并以不穿过中线的方式放置。最后，可打开心包后壁以使心脏向后移动并向左旋转，从而使管道远离胸骨。
