This study aimed at determining the frequencies and pattern of congenital heart lesions among patients who had echocardiographic scan for various cardiovascular-related complaints at the University of Ilorin Teaching Hospital, Nigeria.
All patients referred for echocardiography between May 2004 and April 2007 for various cardiovascular complaints were reviewed. Patients diagnosed with congenital heart disease were selected and analysed for frequencies of lesions, sex ratio and mean age.
Seventy-six patients with a diagnosis of congenital heart disease were reviewed. Ventricular septal defect was the commonest lesion; seen in 27.6% of patients followed by atrial septal defect (21.1%), patent ductus arteriosus (13.1%) and tetralogy of Fallot (11.8%). Others were dextrocardia with situs inversus (6.6%) and bicuspid aortic valve (2.6%).
The distribution of congenital heart lesions is similar to that reported from other parts of the world except for higher frequency of atrial septal defect and lower incidence of bicuspid aortic valve. There has been an improvement in diagnosis of CHD in the middle belt of Nigeria due to availability of echocardiographic imaging facility even though most patients have no access to surgical correction.
本研究旨在确定在尼日利亚伊洛林大学教学医院因各种心血管相关症状接受超声心动图扫描的患者中先天性心脏病变的频率和模式。
回顾了2004年5月至2007年4月期间因各种心血管症状转诊进行超声心动图检查的所有患者。选择诊断为先天性心脏病的患者，分析病变频率、性别比例和平均年龄。
回顾了76例诊断为先天性心脏病的患者。室间隔缺损是最常见的病变，27.6%的患者有该病变，其次是房间隔缺损（21.1%）、动脉导管未闭（13.1%）和法洛四联症（11.8%）。其他病变包括右位心伴内脏反位（6.6%）和二叶主动脉瓣（2.6%）。
先天性心脏病变的分布与世界其他地区报道的相似，但房间隔缺损的频率较高，二叶主动脉瓣的发病率较低。由于有超声心动图成像设备，尼日利亚中部地区先天性心脏病的诊断有所改善，尽管大多数患者无法接受手术矫正。
