Q

Perfusion circulation

A

Blood pumped from the heart through a network of arteries, which branch into smaller arterioles and then into even smaller capillaries. the capillaries are where the actual exchange of oxygen, nutrients, and waste occurs.

Q

Perfusion return

A

After passing through the capillaries, the now-deoxygenated blood is collected by venules and veins, which return it to the heart. from there, it is pumped to the lungs for oxygenation before being sent out to the rest of the body again.

-MI
-heart failure
-cardiomyopathy
-advanced high blood pressure
-congenital problem
-degeneration and calcification of the valve tissue-age related
-Marfan syndrome
-autoimmune disorders- lupus, rheumatoid arthritis, ankylosing spondylitis
-pregnancy

62
Q

Symptoms of valve disorders

A

-all tend to be asymptomatic until hypertrophy and/or HF is present
-MURMUR is first indicator of valve disorder
-SOB, angina, syncope, dysrhythmia, palpitation, dizziness, fatigue, weight gain, poor color, cool extremities, weak peripheral pulses
-complications: HF, cardiogenic shock, thromboembolism, stroke, bleeding from anticoagulation, endocarditis, dysrhythmias

63
Q

diagnostics for valvular and cardiac disorders

A

-echocardiogram/echo: moving image of the heart’s valves and chambers using sound waves from a handheld wand placed on chest (shows chamber size, valve dysfunction, EF, amount of regurgitation)
-transesophageal echocardiogram/TEE: ultrasound of your heart performed by inserting a probe with an ultrasound transducer down esophagus, providing a clearer image than a regular echo because esophagus sits very close to the heart. NPO 6-8 hours before.
-exercise stress echo: walk on treadmill or ride bike then an echo is performed to see how the valves and heart function respond to exercise
-chest x-ray: shows cardiac enlargement and pulmonary congestion
-ECG: electrical activity
-Angiography/cardiac cath: injection of contrast due into a catheter (radial or femoral) to evaluate coronary arteries, heart chambers, and heart valves

64
Q

Mitral valve prolapse

A

leaflets of mitral valve balloon back into the left atrium when the left ventricle contracts, but the valve may still function normally or have only minimal leakage (regurgitation)
-asymptomatic or symptomatic
-overtime causes mitral valve regurgitation which can lead to heart failure
-if palpitations are occurring: stop caffeine, ETOH, smoking, and start anti-arrhythmic medications if needed
-characteristic click sound- mid systolic click!!!

65
Q

Mitral valve regurgitation

A

Mitral valve doesn’t close properly, causing blood to leak backward into the left atrium during systole, increasing workload of the heart.
-backward flow of blood into the LA increases blood volume and raises pressure in the LA and pulmonary vessels- this leads to pulmonary edema and left-sided HF (crackles)
-typically progressive if untreated- heart failure, atrial fibrillation, pulmonary hypertension
-treatment: treating HF (diuretics), valve repair, valve replacement

66
Q

Mitral valve stenosis

A

mitral valve is narrowed or obstructed, making it harder for blood to flow from the LA into the LV. causes increased pressure in the LA, lungs, and RV. decreased blood flow into LV-reduced LV filling causing decreased CO. can cause atrial fibrillation, pulmonary hypertension, HF-left sided and progress to right sided, stroke, infective endocarditis.
-treatment: medications (BB,CCB, diuretics, anticoagulants, antiarrhythmics), balloon valvuloplasty, mitral vale repair or replacement.

67
Q

Aortic valve stenosis

A

valve is narrowed and restricts blood flow from the LV into the aorta and out to the body. LV hypertrophy develops to generate adequate force to open the valve and maintain CO. over time, the LV fails, resulting in left-sided HF, arrhythmias, sudden cardiac death.
-treatment: medications, AVR, balloon valvuloplasty

67
Q

Aortic valve regurgitation

A

valve does not close properly and blood leaks backward from the aorta into the LV during diastole.
-chronic: develops slowly, asymptomatic for a long time
-acute: develops quickly-MEDICAL EMERGENCY!
-results in LV hypertrophy, left sided HF, AF, pulmonary hypertension, sudden cardiac death
-treatment: medications (vasodilators, diuretics, BB, anticoagulants), surgery (aortic valve replacement (AVR)

68
Q

Surgical intervention- valvuloplasty

A

procedure to treat heart valve stenosis. involves using a balloon catheter to widen a narrowed heart valve and improve blood flow. used for patients who have significant valve stenosis but may not be suitable for or do not need immediate surgical valve replacement.
-balloon valvuloplasty: a catheter with a balloon at its tip is inserted into a blood vessel and guided to the heart. once in position across the narrowed valve, the balloon is inflated which expands the valve and helps improve blood flow. after inflation, the balloon is deflated and removed, leaving the valve widened. used for aortic valve stenosis and mitral valve stenosis.

69
Q

Surgical intervention- valve replacement

A

replaces damaged valve with a mechanical valve, bioprosthetic valve (pig, cow, human), or percutaneous valve. open heart surgery (sternotomy), minimally invasive valve surgery (MIVS) using davinci robot, transcatheter aortic valve replacement (TAVR- newer procedure with less pain and shorter post-op)
-mechanical valve: lifelong anticoagulation required, lasts a long time around 20-30 years, audible clicking sound ideal for young patients
-tissue valve: replaced every 7-10 years (may need), silent, for older patients or those with contraindications for anticoagulation

70
Q

Assessment of valvular disorders

A

-VS
-pain (chest pain?)
-monitor for dysrhythmias, palpitations
-heart sounds-murmur
-lung sounds- crackles, orthopnea= pulmonary congestion
-peripheral vascular-S/Sx of poor perfusion
-activity tolerance- S/Sx of worsening HF
-daily weights, Is and Os
-INR monitoring if taking warfarin post-op valve replacement

-actions: HOB elevated, apply O2, medications as ordered (inotropes like Dig), restrict Na and fluids

-educate: regular follow ups, protecting valve from further damage and reducing risk of infective endocarditis-communicate with providers of hx and need for prophylactic antibiotics, good oral care, s/sx of infection, medications, s/sx of decreased CO, daily weights and reporting weight gain, conserve energy, restrict caffeine, ETOH, fluids, and Na

71
Q
