Abstract：
Pulmonary artery stenosis is a rare complication of heart transplantation. It is typically a congenital condition or can be secondary to rheumatic fever, systemic vasculitis like Behcet\'s disease, or Takayasu\'s arteritis. It can also occur as a rarity of a delayed complication post-heart transplant. In this report, we describe the imaging findings of pulmonary artery stenosis in a patient who underwent an orthotopic heart transplant more than 10 years prior. Dynamic cardiac magnetic resonance imaging (MRI), phase contrast imaging, and MR angiography in the management of pulmonary artery stenosis helped in heart and pulmonary circulation. Functional evaluation can be achieved with current multichannel transmit-receive coils. Cardiac gated pre- and dynamic contrast-enhanced MR was performed with phase-contrast imaging for further evaluation confirming the diagnosis of pulmonary artery stenosis.
摘要：
肺动脉狭窄是心脏移植的罕见并发症。它通常是一种先天性疾病，或者可以继发于风湿热，全身性血管炎，如Behcet病，或者是Takayasu的动脉炎.它也可以作为心脏移植后延迟并发症的罕见现象发生。在这份报告中,我们描述了一名10多年前接受原位心脏移植的患者肺动脉狭窄的影像学表现.动态心脏磁共振成像(MRI),相衬成像,和MR血管造影在肺动脉狭窄的治疗中有助于心脏和肺循环。功能评估可以实现与当前多通道发射-接收线圈。使用相位对比成像进行心脏门控预增强和动态对比增强MR，以进一步评估确认肺动脉狭窄的诊断。
