背景从右心室到肺动脉的带瓣管道经常用于儿科心脏手术。然而，管道狭窄和功能不全通常发生在随访中，并导致再次手术。导管支架植入术可延迟手术置换，但可加重肺功能不全。我们开发了一个创新的系统，经皮支架植入术结合瓣膜replacement.Methods一个12岁的男孩与狭窄和功能不全的人工管道，从右心室到肺动脉接受了经皮植入牛颈静脉瓣膜的管道。以及部分缓解管道狭窄。1个月的随访后，没有并发症，病人目前身体状况良好。解释我们已经表明，经皮肺动脉瓣置换术是可能的。随着技术的进一步改进，这种新技术也可能用于其他心脏和非心脏位置的瓣膜置换术。
Background Valved conduits from the right ventricle to the pulmonary artery are frequently used in paediatric cardiac surgery. However, stenosis and insufficiency of the conduit usually occur in the follow-up and lead to reoperations. Conduit stenting can delay surgical replacement, but it aggravates pulmonary insufficiency. We developed an innovative system for percutaneous stent implantation combined with valve replacement.Methods A 12-year-old boy with stenosis and insufficiency of a prosthetic conduit from the right ventricle to the pulmonary artery underwent percutaneous implantation of a bovine jugular valve in the conduit.Findings Angiography, haemodynamic assessment, and echocardiography after the procedure showed no insufficiency of the implanted valve, and partial relief of the conduit stenosis. There were no complications after 1 month of follow-up, and the patient is presently in good physical condition.Interpretation We have shown that percutaneous valve replacement in the pulmonary position is possible. With further technical improvements, this new technique might also be used for valve replacement in other cardiac and non-cardiac positions.
