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 ...

Apicoaortic Shunts for Left Ventricular Outflow Obstruction
The Annals of Thoracic Surgery, 1986Extracardiac conduits were envisioned in 1910 (Carrel) and used clinically in the mid-l950s, yet little long-term postoperative follow-up data currently exist. In this issue of The Annals (p 609), Sweeney and associates discuss 38 patients with apicoaortic shunts created between 1975 and 19M, and analyze the follow-up results.

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].

Right Ventricular Myxoma Obstructing the Outflow Tract
The American Heart Hospital Journal, 2010Cardiac myxomas are benign tumors of endocardial origin. Symptoms might mimic heart disease as well as infectious disease, immunodeficiency, and malignant processes. We present the case of a 59-year-old female patient with a large right ventricular myxoma that was connected to the basal interventricular septum.

Right Ventricular Outflow Tract Obstruction
2013Congenital pulmonary valve abnormalities encompass a spectrum of anomalies that result in right ventricular outflow tract (RVOT) obstruction. Based on the level of obstruction, there are three possible variants: (a) valvular, (b) subvalvular (infundibular stenosis), and (c) supravalvular.

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 and necrotizing enterocolitis.
Radiology, 1984Two neonates had unusually rapid development of necrotizing enterocolitis within 24 hours of birth. Both patients had decreased systemic perfusion secondary to aortic atresia. Onset of either clinical or radiographic manifestations of necrotizing enterocolitis in the first day of life should alert one to the possible presence of severe left ventricular

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.

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.

Right Ventricular Outflow Obstruction Caused by Primary Cardiac Neoplasia
, 1990Obstruction to pulmonary blood flow as a result of neoplasia in the right ventricular outflow tract is described in two dogs. Whereas one dog had exertional syncope and a systolic ejection murmur, the other had signs of congestive failure and hypoxia. In
