A surgical procedure to remove the atheromatous plaque material, or blockage, in the lining of an artery constricted by the buildup of deposits. It is carried out by separating the plaque from the arterial wall.

5

10
Q

rheumatic fever (RF)

A

An inflammatory disease that can involve the heart, joints, skin, and brain.
The disease typically develops two to four weeks after a streptococcal throat infection.

Signs and symptoms include fever, multiple painful joints, involuntary muscle movements, and occasionally a characteristic non-itchy rash known as erythema marginatum.

Valvular (referring to valves) heart disease resulting from rheumatic fever is referred to as rheumatic heart disease.

11
Q

streptococcal pharyngitis

A

also known as strep throat
It is an infection of the back of the throat including the tonsils caused by group A streptococcus (GAS) bacteria.
Common symptoms include fever, sore throat, red tonsils, and enlarged lymph nodes in the neck. Some develop scarlet fever as a result.

12
Q

scarlet fever

A

A disease resulting from a group A streptococcus (group A strep) bacterial infection.

The signs and symptoms include a sore throat, fever, headaches, swollen lymph nodes, and a characteristic rash. The rash is red and feels like sandpaper and the tongue may be red and bumpy.

13
Q

baroreceptors

A

Baroreceptors (or archaically, pressoreceptors) sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained.

any of a group of soluble proteins that combine with and transport fat or other lipids in the blood plasma

24
Q

sick sinus syndrome

A

a disease in which the heart’s natural pacemaker located in the upper right heart chamber (right atrium) becomes damaged and is no longer able to generate normal heartbeats at the normal rate

25
Q

sinus node

A

An area of specialized cells in the upper right chamber of the heart. This area controls your heartbeat. Normally, the sinus node creates a steady pace of electrical impulses. The pace changes depending on your activity, emotions, rest and other factors.

26
Q

atrial flutter

A

A condition in which the heart’s upper chambers (atria) beat too quickly.

27
Q

asystole

A

colloquially referred to as flatline
It is when there’s no electricity or movement in your heart. That means you don’t have a heartbeat.

Asystole is the most serious form of cardiac arrest and is usually irreversible (death).

28
Q

Tetralogy of Fallot

A

A rare condition caused by a combination of four heart defects that are present at birth.
The four defects are:

  1. Ventricular septal defect (VSD) − a hole between the right and left pumping chambers of the heart
  2. Overriding aorta − the aortic valve is enlarged and appears to arise from both the left and right ventricles instead of the left ventricle as in normal hearts
  3. Pulmonary stenosis − narrowing of the pulmonary valve and outflow tract or area below the valve that creates an obstruction (blockage) of blood flow from the right ventricle to the pulmonary artery
  4. Right ventricular hypertrophy − thickening of the muscular walls of the right ventricle, which occurs because the right ventricle is pumping at high pressure
29
Q

tract

A
  1. a system of body parts or organs that act together to perform some function
  2. a bundle of nerve fibers having a common origin, termination, and function
  3. an area either large or small, indefinite or well-defined
  4. extent or lapse of time
  5. a pamphlet or leaflet of political or religious propaganda

(sometimes spelled as Homans sign or called dorsiflexion sign)
It is considered by some physicians to be a sign of deep vein thrombosis (DVT). It was defined by John Homans in 1941 as “discomfort behind the knee upon forced dorsiflexion of the foot.” It is not always seen as being accurate.

A

also known as the TCA cycle (tricarboxylic acid cycle) or the Krebs cycle
It is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.
The TCA cycle is used by organisms that breathe to generate energy, either by anaerobic respiration or aerobic respiration.
