Doppler echocardiography employs a special microphone that allows technicians to measure and analyze the direction and speed of blood flow through blood vessels and heart valves
A normal transesophageal echocardiography (TEE) will typically show clear visualization of cardiac structures, including the chambers, valves, and major vessels of the heart. The images should demonstrate normal heart function, without evidence of structural abnormalities or significant abnormalities in blood flow. Additionally, the procedure should be well-tolerated by the patient with minimal complications.
They would be considered incompetent valves because they are not working properly. You need all the vein valves to work properly for maximum functioning.
Hear disease
the opening and clsoing of valves that creates two beats
AV valves close during the systole phase of the cardiac cycle.
Echocardiography is a medical imaging technique that uses sound waves to create images of the heart. It provides information about the heart's structure, function, and blood flow, and helps diagnose various heart conditions, such as heart failure, heart valve disease, and congenital heart defects.
Valves are made from metals, including brass, bronze, iron, steel, and alloys, as well as from plastics.
I think "poorly spelled" says it best.
Edwards Lifesciences is a leading manufacturer and seller of tissue heart valves and related cardiac repair products such as cardiac cannula, transcatheter valves and minimally invasive hemodymanic monitoring systems.
