Ventricular septal defects (VSDs) are the most common congenital heart defects. Most of the small or moderate size (<6 mm) muscular VSDs close spontaneously within the first two years of life. The usual mechanism of spontaneous closure involves muscular tissue encroachment with superimposed fibrosis or primary fibrous tissue formation around the margins of the defect. We describe an unusual mechanism of spontaneous closure of a muscular VSD.
室间隔缺损(VSD)是最常见的先天性心脏缺陷。大多数小或中等大小(<6毫米)的肌部室间隔缺损在出生后的头两年内会自然闭合。自然闭合的通常机制包括肌肉组织侵入,缺损边缘周围有叠加的纤维化或原发性纤维组织形成。我们描述了一种肌部室间隔缺损自然闭合的不寻常机制。
