MRI Findings in a Baby with Infundibular Muscular Hypertrophy after Balloon Pulmonary Valvuloplasty

磁振攝影表現於經皮氣球擴張肺動脈瓣膜整型術後併發右心室漏斗部肌肉肥厚之一嬰兒病例

摘要


經皮氣球擴張於肺動脈瓣膜整型術後併發右心室漏斗部肌肉肥厚導致出口狹窄會扺消瓣膜整型術的效果。吾人報告一病嬰之磁振攝影的表現。此病童在瓣膜整型後形成明顯的右心室出口阻塞,磁振攝影發現此為右心室漏斗部肌內肥厚之故,因而排除緊急外科介入性療法的必要性,而先接受保守性治療。

並列摘要


Development of infundibular stenosis following percutaneous balloon pulmonary valvuloplasty can cancel the effects of the valvuloplasty. We report on the magnetic resonance imaging (MRI) findings in a baby who developed marked right ventricular outflow track obstruction after valvuloplasty. MRI showed myocardial hypertrophy in the infundibular region, excluding the need for urgent surgical intervention.
