What is the meaning of regurgitant?
Regurgitation: A backward flowing. For example, vomiting is a regurgitation of food from the stomach, and the sloshing of blood back into the heart when a heart valve is incompetent is a regurgitation of blood.
What is a normal regurgitant fraction?
It is measured as the amount of blood regurgitated into a cardiac chamber divided by the stroke volume. This fraction affords a quantitative measure of the severity of the valvular lesion. Normally, no blood regurgitates, so the regurgitant fraction is zero.
How do you calculate Mr regurgitant volume?
The volume of regurgitation is calculated as the difference between transmitral flow and flow across the left ventricular outflow tract LVOT).
Is regurgitant a word?
re·gur·gi·tate v.tr. 1. To cause to pour back, especially to cast up (partially digested food).
What is the difference between regurgitation and vomiting?
A problem that can be confused with vomiting is regurgitation. Vomiting is the ejection of contents of the stomach and upper intestine; regurgitation is the ejection of contents of the esophagus. If food is present in vomit, it is partially digested and a yellow fluid, bile may be present.

Atresia: Absence of a normal opening, or failure of a structure to be tubular. Atresia can affect many structures in the body. For example, esophageal atresia is a birth defect in which part of the esophagus is not hollow, and with anal atresia, there is no hole at the bottom end of the intestine.
How is EROA calculated?
EROA is calculated as RgV (11 mL)/MR VTI (166 mL)=0.07 cm2. AVA indicates aortic valve area; MVA, mitral valve area; and PG, pressure gradient.
What is backflow of blood called?
The backflow of blood is called regurgitation. MVP doesn’t always cause backflow. In fact, most people who have MVP don’t have backflow and never have any related symptoms or problems. When backflow occurs, it can get worse over time and it can change the heart’s size and raise pressure in the left atrium and lungs.
How is EROA measured?
EROA can be calculated as RgV divided by the VTI of the MR jet recorded by CW Doppler. With this method, RgV by volumetric Doppler has been validated against RgV calculated by CMR.
How is echo flow rate calculated?
Flow rate can be simply measured during rest and SE, by dividing the SV by the systolic ejection period (SEP), with a normal rate considered to be 200 ml/s (12).
What causes a person to regurgitate?
Regurgitation happens when a mixture of gastric juices, and sometimes undigested food, rises back up the esophagus and into the mouth. In adults, involuntary regurgitation is a common symptom of acid reflux and GERD. It may also be a symptom of a rare condition called rumination disorder.

How big does a Bothrops nummifer regurgitate its food?
From the Drymarchon I forced the regurgitation of a recently ingested Bothrops nummifer nummifer having a total length of 953 mm. Even at the tender age that must be reckoned by minutes, these young birds were fed, seemingly, by regurgitation.
Why do I have an impulse to regurgitate data?
Some data generation techniques have been shown to closely reproduce images or text found in the training data, for example, while others are vulnerable to attacks that make them fully regurgitate that data. So, whenever my girlfriend brought up Suzy, I had to check my impulse to regurgitate my dad’s response.
