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 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.

Acquired right ventricular outflow tract obstruction in twin‐to‐twin transfusion syndrome; a prospective longitudinal study

Prenatal Diagnosis, 2018
The pathophysiology of right ventricular outflow tract obstruction (RVOTO) in twin‐to‐twin transfusion syndrome (TTTS) recipients is incompletely understood. We aimed to investigate the development and spectrum of RVOTO in TTTS recipients.

Left Ventricular Outflow Tract Obstruction in Children

Cardiology Clinics, 1991
Left 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.

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.

Incidence and Risk Factors for Right Ventricular Outflow Tract Obstruction after the Arterial Switch Operation

The thoracic and cardiovascular surgeon, 2018
Background The aim of this study was to evaluate the incidence and risk factors for the development of right ventricular outflow tract obstruction (RVOTO) after the arterial switch operation (ASO).

Mechanisms, pathophysiology, and diagnostic imaging of left ventricular outflow tract obstruction following mitral valve surgery and transcatheter mitral valve replacement

Echocardiography, 2019
Left ventricular outflow tract obstruction is a serious complication of mitral valve surgery (repair and replacement) and transcatheter mitral valve replacement.

Technique to avoid left ventricular outflow tract obstruction

Asian Cardiovascular and Thoracic Annals, 2016
Preserving 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.
