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.

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.

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.

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

Right Ventricular Outflow Tract Obstruction
2014In this chapter, we will discuss congenital RV infundibulum muscular hypertrophy stenosis, including the muscle bundle of the muscular ventricular septum, combined with the main pulmonary stenosis, ASD or VSD. There is no RV or TV aplasia or dextropositioned aorta such as TOF, pulmonary atresia, or transposition of the great arteries (TGA) (Fig.

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

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.
