Why are heart murmurs interesting in infants and children?

Heart murmurs are common in infants and children, but only a minority of patients with murmurs have heart disease

Association of murmurs with heart disease is higher in who? When does it decrease?

Association of murmurs with heart disease is higher in infants and decreases with age during childhood and adolescence

What are the common causes of murmurs in neonates and infants?

Patent ductus arteriosus
Tricuspid regurgitation
Ventricular septal defects
Peripheral pulmonary stenosis
Pulmonary stenosis
Aortic stenosis
Coarctation of the aorta (check pulses)

PACT PVP

Patent ductus arteriosus:
* Presents when? Occurs as what?
* Best heard where?
* Closes when?
* Prolonged PDA occurs in who?

PDA present just after birth, as part of a normal transition, it usually occurs as a soft systolic murmur which disappears in a few hours or a few days.
Best heard at the left upper sternal border and often described as a continuous “washing machine-like“ sound
Closes in approximately 90% of full-term neonates by 48 hours
Prolonged PDA occurs most commonly in premature infants

PDA is normal for a few hours in the left (sternal) corner of the laundry mat (washing machine)

What does PDA sound like?

"washing machine-like“ sound

What is the most common cardiac abnormality?

VSD

VENTRICULAR SEPTAL DEFECT (VSD): * When is it heard? * Best heard where? * What type of murmur? * Many VSDs will do what?

* VSD is the most common cardiac abnormality * Often not heard at birth, but as the ductus arteriosus closes and the pressure gradient between the two ventricles becomes greater the murmur intensifies * Best heard at the left lower sternal border as a harsh murmur often on day 2 or 3. * Holo- or pansystolic murmur * Many VSDs will close spontaneously over the course of several weeks to months.

When is the VSD more silent?

When it is larger

What are common causes of murmurs in children (over a year old)

* Innocent Still murmur ⭐️ * Cervical venous hum ⭐️ * Atrial septal defect * Mitral regurgitation * Bicuspid aortic valve * Pericarditis | ⭐️ =most common

1/3 to 3/4 of children have what?

an innocent murmur noted at some time between age 1 - 14 years old

INNOCENT STILL MURMUR- * Where is the max intensity? * What does it sound like? * When is it louder? CERVICAL VENOUS HUM- * Best heard where? * When is it the loudest?

INNOCENT STILL MURMUR- * Maximum intensity at the left lower sternal border or between the left lower sternal border and apex. * **Systolic Murmur** with a characteristic vibratory or musical quality. * Louder supine than in the sitting position and in hyperdynamic states (fever, anxiety) CERVICAL VENOUS HUM- * Heard best at the left or right upper sternal borders or infraclavicular or supraclavicular regions. * **Continuous Murmur** that is loudest when the patient is sitting with head extended.

* Innocent still murmur= _ * Cervical venous hum= _

* Innocent still murmur= systolic murmur * Cervical venous hum= continuous murmur

* What is a Foramen Ovale? * What happens during fetal development? * What happens after birth?

* An opening in the septum between the two atria of the heart that is normally present only in the fetus * During fetal development the oxygenation of the blood is via the placenta and not the lungs. The foramen ovale allows blood from the venous system to bypass the lungs and go to the systemic circulation. A layer of tissue begins to cover the foramen ovale during fetal development, and will close it completely soon after birth. * After birth, the pressure in the pulmonary circulation drops, and the foramen ovale closes.

What is a patent foramen ovale? When does it close usually and if does not close?

* NOT a congential heart disease * Flap fusion is complete by age two in 70 - 75 % of children, the remaining 25% have a PFO which persists into adulthood. * Most patients with a PFO remain asymptomatic

What is cyanosis?

a bluish discoloration of the skin resulting from poor circulation or inadequate oxygenation of the blood.

What are noncardiac causes of cyanosis?

* Pulmonary disorders * Persistent pulmonary hypertension * Poor peripheral perfusion * Acrocyanosis

What is Peripheral Cyanosis- Acrocyanosis? Where does the blue color come from?

* Painless condition where the small blood vessels in your skin constrict, turning the color of your hands and feet bluish * The blue color comes from the decrease in blood flow and oxygen moving through the narrowed vessels to your extremities

What are the cardiac causes of cyanosis 🌟

●Transposition of the great arteries (TGA) ●Tetralogy of Fallot (TOF) ●Truncus arteriosus ●Total anomalous pulmonary venous return (TAPVR) ●Tricuspid valve abnormalities

What is central cyanosis?

Congenital heart disease

Cyanotic cardiac lesions account for approximately _ of all congenital heart disease (CHD) cases and _ of potentially fatal forms of CHD

Cyanotic cardiac lesions account for approximately **15 %** of all congenital heart disease (CHD) cases and **1/3** of potentially fatal forms of CHD

A patient that has a known history of cardiovascular disease including a myocardial infarction and positive ankle-brachial index indicating peripheral arterial disease in his left leg is now having some issues with erectile dysfunction (ED). The clinician suspects it may be due to medications or further vascular disease. He does not complain of any other symptoms. If his symptoms are related to vascular disease, where would the lesion likely be located? A. Superficial femoral B. Popliteal C. Common femoral D. Aortorenal E. Iliac pudendal

E. Iliac pudendal

A 61-year-old retired librarian was recently diagnosed with ovarian cancer. She was otherwise healthy until her recent cancer diagnosis. She has not been feeling well lately and has had a cough and some mild shortness of breath for the past couple of days. She now presents to the clinic complaining of pain and swelling in her right groin and leg, which she says is been there for about a week but is worsening. On physical examination, 2+ edema of the right leg up to the thigh; 1+ femoral, popliteal, dorsalis pedis, and posterior tibial pulses; and no significant erythema are noted. What is the chief concern with this patient? A. Acute arterial occlusion B. Superficial thrombophlebitis C. Ovarian metastasis D. Acute lymphangitis E. Pulmonary embolism (PE)

E. Pulmonary embolism (PE) Cancer patients are at high risk of deep venous thrombosis (DVT), and, with the presenting symptoms of swelling and pain in her groin, along with recent history of cough and shortness of breath, this patient's presentation is suspicious for PE.

A 68-year-old retired administrative assistant complains of a 3-month history of recurring pain after ambulating that radiates from her back in the upper lumbar region into both buttocks, bilateral thighs, and mid-calf regions. Her pain is typically improved by sitting or by leaning forward. The origin of her pain is likely secondary to which of the following? A. Peripheral arterial disease (PAD) B. Acute arterial occlusion C. Venous stasis D. Neurogenic claudication E. Abdominal aortic aneurysm

D. Neurogenic claudication * Neurogenic claudication can mimic PAD by causing pain related to walking; however, it is typically relieved simply by sitting or by leaning forward

A 73-year-old retired salesman presents to the Emergency Department complaining of chest pain that started about 2 hours ago. Electrocardiogram, cardiac enzymes, and chest x-ray are normal. The nurse notes that his blood pressures in the right arm are significantly lower than of blood pressures in his left arm. Based on history and physical examination, which of the following will most likely explain his signs and symptoms? A. Dissecting aortic aneurysm B. Myocardial infarction (MI) C. Pericarditis D. Pulmonary embolism (PE) E. Coarctation of the aorta

A. Dissecting aortic aneurysm

A 19-year-old carwash attendant sustained a laceration to the ulnar aspect of his mid-forearm while at work last week. He did not have it evaluated at that time and is now noticing purulent discharge and increasing pain from the wound along with fever and chills. Where would the clinician expect to find the first signs of lymphadenopathy? A. Epitrochlear nodes B. Infraclavicular nodes C. Central axillary nodes D. Lateral axillary nodes E. Cervical chain nodes

A. Epitrochlear nodes

A 44-year-old retail salesperson has noticed an increasing dilatation of the veins in her legs. Upon inspection, it is noted that she has significant varicosities on the posterior aspects of both legs which begin in the lateral side of the foot and pass upward along the posterior calf. The remainder of the veins in the legs appears normal at this time. Which veins are currently affected? A. Femoral B. Great saphenous C. Small saphenous D. Dorsal venous arch E. Perforating

C. Small saphenous

A clinician, evaluating a patient for valvular competency in the communicating veins of the saphenous system, starts with the patient supine, then elevates one leg to about 90° to empty it of venous blood. Next, the great saphenous vein in the upper part of the thigh is occluded with manual compression, and the patient stands. The clinician keeps the vein occluded while watching for venous filling in the leg. Which test is being performed? A. Ankle-brachial index B. Allen C. Trendelenburg D. Romberg E. Straight-leg raise

C. Trendelenburg

The clinician is palpating pulses in the foot of a diabetic patient while in the clinic. A strong pulse is felt located on the dorsum of the foot, just lateral to the extensor tendon of the big toe. Which artery is being assessed?

Dorsal Pedis

A 32-year-old cabdriver complains of pain in his left leg. He has a history of type 2 diabetes, is a smoker, and recently was diagnosed with hypertension. He does not remember injuring his leg; however, he notes that there is a small wound on the lateral aspect of his mid-shin. Upon examination, some mild erythema surrounding the wound and flat, nonpalpable red streaks progressing up his leg are noted. What do these streaks likely represent? A. Occluded arterial vessels B. Dilated arterioles C. Dilated veins secondary to incompetent valves D. Draining lymphatic channels E. Thrombus formation in a superficial vein

D. Draining lymphatic channels Acute lymphangitis is typically caused from an acute bacterial infection of the skin that causes red streaks from distal drainage through the lymphatic system. The streaks are typically flat, not palpable cords as found in thrombus formation in a superficial vein

When assessing for the femoral pulse, where should the clinician begin deeply palpating? A. Below the inguinal ligament, just medial to the anterior superior iliac spine B. Below the inguinal ligament, just lateral to the symphysis pubis C. Below the inguinal ligament, midway between the anterior superior iliac spine and symphysis pubis D. Above the inguinal ligament, just medial to the anterior superior iliac spine E. Above the inguinal ligament, just lateral to the symphysis pubis

C. Below the inguinal ligament, midway between the anterior superior iliac spine and symphysis pubis
