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.

Anteroapical Stunning and Left Ventricular Outflow Tract Obstruction
Mayo Clinic Proceedings, 2001Dynamic left ventricular outflow tract (LVOT) obstruction is typically observed in the setting of hypertrophic cardiomyopathy. It has also been reported with concentric LV hypertrophy, excessive sympathetic stimulation, and acute myocardial infarction. We describe 3 patients with chest discomfort after emotional stress, who had pronounced abnormalities

An Unusual Cause of Left Ventricular Outflow Tract Obstruction
Journal of Cardiothoracic and Vascular Anesthesia, 2011YPERTROPHIC CARDIOMOPATHY (HCM) is a complex condition with an extensive phenotypic expression and a broad clinical spectrum. Mutations in the sarcomeric proteins lead to abnormal hypertrophy, especially of the interventricular septum. 1 The prevalence of this condition in the adult population is approximately 0.2%, and it is considered the most common

Echocardiographic assessment of left ventricular outflow tract obstruction
American Heart Journal, 1983The assessment of a patient with suspected left ventricular outflow tract (LVOT) obstruction is a common clinical problem. Symptoms such as anginal pain, congestive heart failure, vertigo, or syncope may be due to associated diseases (mainly coronary artery disease), but are often the ominous signs of critical obstruction.

The Transmitral Approach to Left Ventricular Outflow Tract Obstruction
The Annals of Thoracic Surgery, 1983Left ventricular outflow tract obstruction is a particularly vexing problem in patients with complete transposition (atrioventricular concordance and ventriculoarterial discordance) and intact ventricular septum. Previous techniques, such as resecting the obstructive lesion through the pulmonary valve or bypassing the obstruction, have not given ...

Surgical Management of Left Ventricular Outflow Tract Obstruction
Journal of Cardiac Surgery, 2011Left ventricular outflow tract obstruction (LVOTO) is caused by a spectrum of lesions. This study was performed to determine the outcomes of surgical management of LVOTO.All patients who had surgery of the LVOT between 2002 and 2010 were retrospectively reviewed.There were 103 consecutive patients with median age 6.8 years (range 8 days to 62 years ...

Left Ventricular Outflow Tract Obstruction in the Adult
2019Left ventricular outflow tract obstruction in the adult with congenital heart disease is a general term that includes all the obstructive lesions affecting the left ventricle, aortic valve, and the aortic arch. These lesions can be caused by residual defects that were not completely addressed in childhood or by acquired conditions such as hypertrophic ...

Left ventricular outflow tract obstruction in ICU patients
Current Opinion in Critical Care, 2016Left ventricular (LV) outflow tract (LVOT) obstruction (LVOTO) is not unusual in ICU patients particularly with septic shock.LVOT was first described in patients with hypertrophic cardiomyopathy and was defined as LV wall thickness at least 15 mm. LVOT is usually because of systolic anterior motion of the mitral valve.

Autosomal dominant inheritance of left ventricular outflow tract obstruction
American Journal of Medical Genetics Part A, 2005Most nonsyndromic congenital heart malformations (CHMs) in humans are multifactorial in origin, although an increasing number of monogenic cases have been reported recently. We describe here four new families with presumed autosomal dominant inheritance of left ventricular outflow tract obstruction (LVOTO), consisting of hypoplastic left heart (HLHS ...
