Left Ventricular Outflow Tract Obstruction

NeoReviews, 2006
A term female newborn presents with a prenatal diagnosis of cardiac masses on prenatal echocardiography. ### Prenatal History: ### Birth History and Presentation: The baby was delivered by elective cesarean section after rupture of membranes with clear fluid. Apgar scores were 9 at both 1 and 5 minutes.

Left ventricular outflow tract obstruction

Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2004
Left ventricular outflow tract obstruction can occur at the supravalvar, valvar, or subvalvar level. Each level of obstruction is associated with distinct symptomatology, natural history, and operative approach. Reconstructive techniques can usually be used with low operative risk and excellent immediate and longer-term outcomes.

Right ventricular outflow tract obstruction

2013
Congenital 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

2009
Left ventricular outflow tract obstruction (LVOTO) accounts for 5–10% of all congenital heart defects. LVOTO occurs at the valvar (70%), subvalvar (14%), and supravalvar (8%) level, and several levels of obstruction often coexist (8%) [1]. Another type of muscular subaortic stenosis, present with hypertrophic cardiomyopathy, is known as hypertrophic ...

Reversible obstruction of the ventricular outflow tract

The American Journal of Cardiology, 1963
Abstract Obstruction of the left ventricular outflow tract with characteristics of subaortic muscular hypertrophy has been produced in a human subject and 2 of 8 dogs by infusion of isoproterenol. In 2 other dogs with outflow tract gradients in the “control” state, infusion of blood relieved the obstruction.

Right Ventricular Myxoma Obstructing the Outflow Tract

The American Heart Hospital Journal, 2010
Cardiac 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.
