Ventricular septal defect (VSD) is the commonest type of congenital heart lesion accounting for up to 40% of congenital heart defects. Well timed VSD closures are reported to yield excellent long-term outcomes. Late surgical VSD closures, particularly from the developing countries, are infrequently reported.
We report three cases of African children aged between 13 and 14 years who had late VSD presentations. They reported complaints of growth failure and recurrent respiratory infections since early infancy which necessitated frequent visits to primary health care facilities. They were found to have large ventricular septal defects by thoracic echocardiography. Diagnostic cardiac catheterization was done to all three patients to rule out irreversible pulmonary hypertension. After promising cardiac catheterization findings, they all underwent successful surgical VSD repair with good early outcomes.
VSD surgical closure is ideal in children below 2 years, however, it can be done in children who present at advanced age despite being considered high risk patients. All three of our patients who presented late had successful surgical VSD repairs with promising immediate outcome. The role of genetics in the protection against developing irreversible pulmonary vascular disease in these patients is a possible area for future studies.
室间隔缺损(VSD)是最常见的先天性心脏病变,占先天性心脏病的 40%。及时进行 VSD 闭合术据称可获得极佳的长期效果。来自发展中国家的晚期手术 VSD 闭合术报道较少。
我们报告了三例非洲儿童的病例,年龄在 13 至 14 岁之间,有晚期 VSD 表现。他们从婴儿早期开始就出现生长发育不良和反复呼吸道感染的症状,这使他们需要频繁前往初级保健机构就诊。胸部超声心动图发现他们均存在较大的室间隔缺损。对所有三名患者均进行了诊断性心导管检查,以排除不可逆性肺动脉高压。在心导管检查结果良好后,他们均成功接受了 VSD 修补术,早期结果良好。
VSD 手术闭合术在 2 岁以下的儿童中是理想的,但即使被认为是高危患者,也可以在年龄较大的儿童中进行。我们报告的所有三名晚期就诊的患者均成功接受了 VSD 修补术,即时效果令人满意。遗传因素在保护这些患者免受不可逆性肺血管疾病发展方面的作用可能是未来研究的一个方向。
