Left Ventricular Outflow Obstruction in Infancy and Childhood
Archives of Surgery, 1969Left ventricular outflow obstruction occurs in 3% to 5% of cardiac anomalies encountered in the pediatric age group. The obstructing lesion may be supravalvular, valvular, subvalvular, or a combination of more than one lesion. 1,2 The indication for surgical intervention in these patients is not yet fully defined.

Left Ventricular Outflow Tract Obstruction in Children
Cardiology Clinics, 1991Left ventricular outflow tract obstruction is classified by site of presentation into valvular, subvalvular, and supravalvular forms. This disorder affects multiple age groups, and success rates of operative therapies vary dramatically. Abnormalities in any of the three principal anatomic sites of the LV outflow tract can lead to obstruction.

Left ventricular outflow obstruction
1986The echocardiographic hallmark of a congenitally stenotic aortic valve is the presence of systolic doming [1]. During ejection, the aortic cusps curve toward the center of the aortic lumen without separating completely. M-mode echocardiography is not reliable in the detection of this restricted valvular opening as echoes from the base of the doming ...

Right ventricular outflow obstruction
1986Pulmonary valve stenosis can be diagnosed only indirectly by M-mode echocardiography: the diagnosis is based essentially on the effects of abnormal presystolic ventricular pressure on pulmonary valve opening [1].

Left ventricular outflow tract obstruction
2003Aortic stenosis is rare in infancy. It is present in 0.004–0.34% of live births; 75% of patients are males. It ranks 9th among critical congenital heart diseases in infants (2.9%). Incidence increases with age to become the second most common congenital heart disease after ventricular septal defect in the third decade of life.

Left Ventricular Outflow Tract Obstruction
2015Left ventricular outflow tract (LVOT) obstruction is a general term that includes all the obstructive lesions affecting the left ventricle and the aortic arch. Subaortic stenosis can be caused by fibrous rings, hypertrophied muscle, or abnormal mitral valve attachments.
