Management of outflow tract ventricular arrhythmias

Current Opinion in Cardiology, 2015
Outflow tract ventricular arrhythmias represent an important chapter in clinical electrophysiology. Recent investigations enhance the knowledge in that field and highlight new important concepts in ventricular arrhythmogenesis.Recent publications have revealed new interesting results in the field of outflow tract ventricular arrhythmias.

Left Ventricular Outflow Tract

2013
Left ventricular outflow tract obstructions (LVOTO) encompass a series of stenotic lesions starting in the left ventricular outflow tract (LVOT), including the aortic valve and extending to the ascending aorta. Depending on definition, also intraventricular obstruction and hypoplastic left heart syndrome are included in the types of LVOTO.

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.

Outflow tract ventricular arrhythmias: An update

Trends in Cardiovascular Medicine, 2015
During the last 20 years, the molecular etiology for many ventricular tachyarrhythmias once referred to as "idiopathic," has been elucidated. These arrhythmias are due to mutations in ion channels or structural proteins and include ventricular tachyarrhythmias due to long and short QT syndromes, Brugada syndrome, and catecholaminergic polymorphic ...

Hemodynamics of the ventricular outflow tract

Journal of Biomechanics, 1970
Abstract The purpose of this report is to formulate from the equations of fluid mechanics, assuming inviscid flow of an incompressible fluid, an equation for the fluid dynamics of the ventricular outflow tract. The unsteady flow term of the equation implies the possibility of a negative pressure gradient from the left ventricle to the proximal aortic

Right ventricular outflow tract obstruction

2014
Conditions that result in right ventricular outflow tract obstruction, i.e. valvular, supravalvular, and branch pulmonary stenosis, are discussed.

Left Ventricular Outflow Tract Anomalies

2012
Congenital left ventricular outflow tract obstruction accounts for 10% of all congenital heart disease. For practical purposes, the site of obstruction is classified anatomically as valvar, subvalvar, or supravalvar, or as a combination of the three (multilevel stenosis).

Left Ventricular Outflow Tract Obstruction

2015
Left 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 Lesions

2007
Normal aortic valve is trileaflet. Congenital forms of valve disease are either unicuspid, bicuspid, or quadricuspid. Bicuspid valve is the most common congenital aortic valve disease, where the aortic valve is anatomically made of two leaflets or more but often functioning as bileaflet valve due to leaflet fusion.
