Accessory mitral valve tissue is an uncommon congenital malformation and a rare cause of left ventricular outflow tract obstruction. Although echocardiography provides a "gold standard" for evaluation of valves, the high temporal and spatial resolutions of computed tomography technology makes it useful in the assessment of valvular structure and function.
瓣下二尖瓣组织是一种不常见的先天性畸形,也是左心室流出道梗阻的罕见原因。尽管超声心动图为瓣膜评估提供了“金标准”,但计算断层扫描技术的高时间和空间分辨率使其在瓣膜结构和功能评估方面具有价值。
