A ventricular outflow tract is a portion of either the left ventricle or right ventricle of the heart through which blood passes in order to enter the great arteries. [1]The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity that connects to the pulmonary artery.
A ventricular outflow tract obstruction is a heart condition in which either the right or left ventricular outflow tract is blocked or obstructed. These obstructions represent a spectrum of disorders. Majority of these cases are congenital, but some are acquired throughout life. [1]
This open-heart surgery is designed to relieve the right ventricular outflow tract stenosis by careful resection of muscle and to repair the VSD. [58]: 154 The right ventricle outflow tract can be reconstructed using mainly 2 procedures: a transannular patch (TAP) or a pulmonary valve-sparing procedure (PVS). The decision on the type of the ...
[4] [6] Ventricular function and size are assessed with an echocardiogram. [4] The right ventricle and the anatomy of the outflow tract, including any anatomical variations, are also assessed with cardiac magnetic resonance imaging. [4] [6] The severity of the outflow tract defect or pulmonary regurgitation is assessed with Doppler ...
Usually, APVS occurs together with other congenital heart defects, most commonly ventricular septal defect and right ventricular outflow tract obstruction. It is sometimes considered a variant of Tetralogy of Fallot. [1] The first case of absent pulmonary valve syndrome was reported Crampton in 1830. [2]
For patients with TOF, though, the right ventricular outflow obstruction might block the normal blood flow so much that the pressure in the right ventricle has to be really high to get past it. Well the high right-sided pressures means that the left side of the heart actually becomes the path of least resistance and deoxygenated blood shunts ...
Premature ventricular contraction usually originates from an area of Ectopic focus. In this illustration ectopic area is near papillary muscles in the left ventricle. Most commonly in healthy hearts PVCs occur near right ventricular outflow tract (RVOT). A premature ventricular contraction on an EKG, marked by the arrow: Specialty: Cardiology
[1] [2] It allows the surgeon to reconstruct the right ventricular outflow tract without needing to connect the proximal and distal sections with a graft. [2] [3] It also enables the surgeon to avoid compressing the coronary arteries and relieves compression of the bronchi in cases where the pulmonary artery is severely dilated or aneurysmal.
