摘要:
[摘要] 目的 应用超声心动图技术探讨右室流出道狭窄(right ventricular outflow tract stenosis,RVOTS)患者合并肺动脉高压(pulmonary arterial hypertension,PAH)的形成原因。方法 回顾性分析经外科手术证实的8例RVOTS合并PAH患者的术前超声图像及临床资料。结果 形成PAH的原因包括:3例存在大动脉水平分流,2例合并主动脉瓣反流和房颤等左心疾患,1例PAH为一过性,另2例分别为室间隔缺损(ventricular septal defect,VSD)与RVOTS不匹配合并大动脉水平分流,VSD在RVOTS之后、大动脉水平分流合并主动脉瓣下狭窄和主动脉瓣反流等。结论 少数先天性心脏病RVOTS患者因多种原因可合并PAH,超声心动图检查可进一步明确其原因,为临床干预提供可靠依据。

Abstract:
[Abstract] Objective To investigate the causes of right ventricular outflow tract stenosis(RVOTS) complicated with pulmonary arterial hypertension(PAH) using echocardiographic technique. Methods The preoperative echocardiographic images and clinical data of 8 patients with RVOTS and PAH proved by surgery in our hospital were retrospectively analyzed. Results The possible causes of PAH included that arterial-level shunt in 3 cases, left heart diseases including aortic regurgitation and atrial fibrillation in 2 cases, and transient PAH in 1 case. There were multiple influencing factors in the other 2 cases,such as mismatch between ventricular septal defect(VSD) and RVOTS with arterial-level shunt, and VSD occurring after RVOTS, followed by left heart diseases of arterial-level shunt complicated with subaortic stenosis and aortic regurgitation. Conclusion A few congenital heart disease patients have RVOTS complicated with PAH for many reasons. It is necessary to further analyze the causes of the disease to provide a reliable basis for the selection of clinical interventions.
