Left Ventricular Outflow Tract Obstruction
Critical Care of Children with Heart Disease, 2009Left 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 ...

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.

Left Ventricular Outflow Tract Obstruction
, 2017Left ventricular outflow tract obstruction (LVOTO) can occur at the valvular, subvalvular, or supravalvular level. In general, there is an obstruction to forward flow which increases afterload, and if untreated, can result in hypertrophy, dilatation, and

Left ventricular myxoma with dynamic left ventricular outflow tract obstruction
Postgraduate Medical Journal, 2018A 24-year-old man presented with sudden motor aphasia and right hemiparesis which recovered spontaneously over 30 min. Cardiac evaluation revealed a short mid-systolic murmur at the aortic area. He was in sinus rhythm. Transthoracic echocardiography revealed a large pedunculated mass in the left ventricular outflow tract with phasic prolapse through ...

Technique to avoid left ventricular outflow tract obstruction
Asian Cardiovascular and Thoracic Annals, 2016Preserving the subvalvular mitral valve apparatus during mitral valve replacement is extremely important to minimize progressive postoperative left ventricular remodeling and dysfunction. We describe a simple and reproducible surgical technique that prevents the complications that can occur after total mitral anterior leaflet preservation.
