A 73-year-old Japanese man was admitted with an asymptomatic pulmonary artery aneurysm. However, chest X-ray and contrast-enhanced thoracic computed tomography revealed a protrusion at the second left branch that in fact was a pulmonary artery aneurysm with a diameter of 50 mm. Transesophageal echocardiography showed a bicuspid pulmonary valve, and cardiac catheterization revealed pulmonary stenosis with a pressure gradient of 45 mmHg, but no other heart diseases were noted. An extremely rare pulmonary artery aneurysm associated with an isolated bicuspid pulmonary valve was diagnosed.
一位 73 岁的日本男性因无症状性肺动脉瘤入院。然而，胸部 X 光和增强胸部计算机断层扫描显示第二左支有一处突起，实际上是一个直径为 50 毫米的肺动脉瘤。经食管超声心动图显示为二叶式肺动脉瓣，心导管检查显示肺动脉瓣狭窄伴 45mmHg 的压力梯度，但未发现其他心脏病。诊断为一种极其罕见的与孤立性二叶式肺动脉瓣相关的肺动脉瘤。
