The vena cava is the largest vein in the body ... parts (inferior vena cava). Mitral stenosis occurs when the mitral valve's opening narrows, impairing blood flow from the left atrium to the ...

indicates normal age-specific E/A and high E/E' and confirmed by the differences in durations between the mitral atrial flow and the reverse pulmonary vein flow during atrial systole; severely ...

disrupting venous outflow from the eye and resulting in CRVO (14). In this patient, echocardiography revealed signs of severe PAH, including right ventricular and atrial enlargement, tricuspid ...

Hypoplastic left heart syndrome (HLHS) is a continuum which can affect all left sided cardiac structures, from the mitral ... pulmonary venous congestion on chest x ray. These infants are generally ...

Background Although the prognostic implications of severe mitral regurgitation (MR) are well recognised, they are less clear ...

NEW research has revealed that residual mitral regurgitation (MR) assessed by 3D -Vena Contracta Area (VCA) during ...

LONDON, England—A new analysis is emphasizing the prognostic significance of residual tricuspid regurgitation (TR) following mitral valve-in-valve procedures, with investigators showing that those ...

Veins in the lungs, or pulmonary veins, play a critical role not only in lung functioning but also in maintaining sufficient ...

Contraction of the foot and calf muscles initiates cephalad flow of blood and opens the one-way valves within the veins, which prevent retrograde flow after closing. Dysfunctional valves cause ...

A large study found that greater exposure to long-term air pollution was linked with increased risks for blood clots that can occur in deep veins, which, if untreated, can block blood flow and cause ...
