Abstract

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.

摘要

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。
