Patho final Flashcards
infective endocarditis
Aortic Valve with bacterial endocarditis
Pericarditis
The pericardium (lining of the heart) becomes inflamed.
three types of cardiomyopathy
Hypertrophic CM-thickened left ventricular wall
Congestive or Dilated CM- Dilated Left Ventricle (Enlarged heart)
Restrictive: myocardial fibers become infiltrated with abnormal substances(toxins) causing ventricular dysfunction
Stenosis
Occurs in the Aortic and Mitral valves. Valve opening does not open all the way, not enough blood passes through.
structure that delivers oxygenated blood from the placenta to the fetus
ductus venous
higher vascular resistance in the arterial systematic circulation would most likely lead to
Increased workload of the right ventricle
The lowest pressure is in the
Right Atrium of the adult cardiopulmonary circulation
Transposition of the great vessels has a
Right to left shunt
Which Blood Lipid is considered to be protective against the development of coronary artery disease
HDL, high density lipoprotein
After a myocardial infarction, which area does not heal?
Infarction
Which of the following is considered a lethal dysrhythmia or arrhythmia
ventricular fibrillation
Clinical manifestations of Left Ventricular Heart Failure include:
Dyspnea, Pink frothy sputum, Fatigue, Crackles
Clinical manifestations of Right Ventricular Heart Failure include:
Edema, weight gain, neck vein distention, enlargement of liver and spleen
Left ventricular heart failure(CHF) can lead to movement of fluid from capillaries to alveoli. This can lead directly to:
Crackles for lung sounds
Left ventricular heart failure can lead to right ventricular heart failure and result in:
Peripheral edema
In the development of coronary artery disease CAD, what usually happens first?
Endothelial damage and lips deposition
Risk factors for CAD do not include:
female gender
With myocardial infarction, the zone of infarction:
does not heal/becomes scar tissue
clinical manifestations of myocardial infarction does not include:
warm, flushed skin
Ventricular septal defect may cause
increased pressure in the Right ventricle
With coarctation of the aorta, why is pre ductal worse than post ductal
Post ductal allows some blood to shunt thru the patent ductus arterioles
Cyanosis is likely to be seen in
Tetralogy of ballot
If a patient has normal O2 levels in the right Atrium, Right Ventricle, and left atrium, what is likely occurring?
blood shunting from the Right Ventricle to the Left Ventricle
Regurgitation, like stenosis occurs in the aortic and mitral valves, it is when
the valve does not close all the way, so blood leaks backwards.
fetal circulation structures include the
dusts, venous, foramen ovale, ductus arteriosus
Cardiac shunt– Left to right:
oxygenated blood from the left side goes into the right side and is (ASYNOTIC)
Cardiac shunt right to left :
less oxygenated blood from the right side goes into the left side or the systemic circulation(CYANOTIC)
Acyanotic conditions include
ASD, Atrial Septal Defect, VSD, Ventricular Septal Defect, PDA Patent Ductus Arteriosus, COA, Coarctation of Aorta
Atrial Septal Defect
An atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria)
Ventricular Septal Defect
A ventricular septal defect (VSD), a hole in the heart, is a common heart defect that’s present at birth (congenital). The hole occurs in the wall that separates the heart’s lower chambers (septum) and allows blood to pass from the left to the right side of the heart.
PDA, Patent Ductus Arteriosus
Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby’s circulatory system before birth that usually closes shortly after birth.
Coarctation of the Aorta
Coarctation of the Aorta (CoA or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word “coarctation” means narrowing. Coarctations are most common in the aortic arch.
cyanotic conditions include:
Tetralogy of Fallot
Transposition of Great Vessels
Development of atherosclerosis: (CAD)
Inflammation starts things, damages the epithelium allowing lipids to deposit in the intima. The lipids are oxidized and attract monocytes which enter the intima and become macrophages. Macrophages ingest LDL then are transformed into foam cells. Foam cells release cytokines which cause further inflammation and injury to the
intima, A fatty streak is formed in intima (collection of foam cells)-(yellow, filled with lipids), starts to cause narrowing, fibrous plaque forms (fatty streak collected collagen, fibers, ect., , complicated lesion(advanced)- fibrous plague hemorrhages causing a clot formation and obstruction.
The three most dangerous risks for CAD or Coronary Artery Disease are:
Cigarette smoking, Hypertension, and hyperlipidemia
Clinical manifestations for ischemia (to the heart)
Transient 3-20 minutes, sub-sternal pain, discomfort, heaviness, pressure,tightening, squeezing, or aching. May Radiate to neck, left-arm, jaw, teeth, back.
clinical manifestations for a Myocardial Infarction:
Include the same symptoms as Ischemia, but also include: Indigestion, nausea, vomiting, diaphoresis, cool, clammy skin, Change in BP and or HR and Rythym
* during an MI, Nitroglycerin does not usually relieve
What similar problem does backward effects of LVF lead to that is the SAME as what the back ward effects of RVF leads to.
Increased volume, pressure in the venous system, edema
What different problem does backward effects of of RVF lead to that backwards effects of RVF leads to.
Increased volume/pressure in the pulmonary system.
Tetralogy of Fallot is Cyanotic and is cause by
Right to Left shunting through Ventricular Septal Defect, and RV to Aorta
Four steps of PAthophys of infective endocarditis are:
- Endocardium is “prepared” to be colonized by having endothelial damage
- Colonization can then occur(because of NBT and 1 above)
- Infective vegetation forms
- clotting cascade, fibrin ect. - Valve Dysfunction, emboli ect.
Transposition of Great vessels is cyanotic and is caused by
two circulations, the systemic circulation does not have 02 which can be a bit of a problem
Normal pressure in the right atrium is about
5mmHg
What about cigarette smoking leads to decreased 02 delivery to tissues
Carbon Monoxide
What starts the process of CAD development
Inflammation damaging the epithelium
Which is a clinical manifestation of Myocardial Infarction, but not of Myocardial Ischemia?
Diaphoresis(sweating)
Which two valves are closed during systole
mitral and tricuspid
Which two valves are closed during diastole
aortic, and pulmonic
Backward effect of Left Ventricular Heart Failure first leads to:
Increased pulmonary artery pressure
What clinical manifestations are due to the forward effects of left ventricular failure.?
exercise intolerance
sensory perception is
the body’s ability to receive sensory stimuli and to consciously translate that data into meaningful information.
In rheumatic fever, the systemic inflammation effect on the nervous system causes:
Syndenham’s chorea
cyanosis would most likely be seen with
Tetralogy of Fallot
Aortic valve regurgitation is least likely to produce
A systolic murmur
Strabismus
“Crossed eyes” deviation of one eye from the other when looking at an object. Most commonly caused by weak hypertonic muscle in affected eye, normal up to age 4 months. Clinical manifestations are deviation of eye, and diplopia (double vision).
Cataracts
Development of opacities(cloudiness) of ocular lens. Caused by old age mostly, lens becomes more stiff and opaque with age. Clinical manifestations include: decreased visual acuity, increase in glare, decreased color perception, white light reflex(instead of red) in pupil area
