二尖瓣前叶裂隙常伴发于永存房室通道型房间隔或室间隔缺损(心内膜垫缺损)。单纯性二尖瓣裂隙是二尖瓣关闭不全少见的原因,临床上与其他原因引起二尖瓣关闭不全的鉴别十分团难,多需经手术或尸检得以诊断。本文报道应用两维超声心动图诊断9例单纯二尖瓣裂隙的患者,并对其超声、临床、血流动力学进行了研究。方法:患者9例(女性6例、男性3例),出生后1天～12岁,均行心电图及胸部 X 线检查,4例经心导管检查及电影左心室造影证实有1～4级反流,其
Mitral anterior lobe fissures often associated with perpetual atrioventricular atrial septal or ventricular septal defect (endocardial cushion defect). Simple mitral valve mitral valve mitral regurgitation is uncommon rare reasons, clinically and other causes of mitral regurgitation is very difficult to identify, more need to be diagnosed by surgery or autopsy. This paper reports the application of two-dimensional echocardiography in the diagnosis of nine patients with simple mitral valve stenosis, and its ultrasound, clinical, hemodynamics were studied. Methods: Nine patients (6 females and 3 males) and 1 day to 12 years of age underwent electrocardiogram and chest X-ray examination. Four patients underwent cardiac catheterization and left ventricular angiography to confirm grade 1 to 4 Flow, it
