What are cardiac masses (6)
|
Cardiac tumors, thrombus, vegetation, Iatrogenic material (pacemaker) Normal variants, extracardiac structures.
|
|
Echo good to evaluate heart for masses
|
where it is. how big masses are. HEMODYNAMIC EFFECT OF BLOOD FLOW through the heart
|
|
Cardiac tumors
|
Primary (rare)
Secondary (majority) |
|
which one is more common primary or secondary ?
|
Secondary is more common for cardiac tumors
|
|
Can you tell on echo if the tumor is benign or malignant
|
NO
we can't definitely distinguish between benign and malignant tumor |
|
On echo we can assess the mass by
|
the location, extent of mass, size of mass, where it originates.
|
|
Secondary tumors are ALL malignant WHY?
|
bc the metastasis from somewhere else. The can occur in 10% of all Fatal Malignancy
|
|
Most common primary CA that metastasize (spreads) to the heart ?
|
LUNGS
30% of cardiac secondary tumors are from the lungs |
|
Other common primary CA that metastasize to heart
|
breast, kidney, liver, melanoma, AIDS related Lymphoma, Leukemia, Osteogenicsacroma
|
|
There are certain tumors that metastasize to the IVC and as a result spread into the RA
|
Hypernephroma, Hepatoma, Intravenous leiomyomatosis tumors *rare
|
|
if you see a mass in the RA
|
you need to evaluate the IVC
|
|
What tumor tends to spread to the IVC (CA)
|
WILMS TUMOR
anytime you see renal mass -look at IVC |
|
Primary tumors (RARE)
|
benign
malignant |
|
do we treat benign primary tumors?
|
yes bc they can be obstructive, break off and cause emboli
|
|
Although most cardiac tumors are benign they can become a problem. Can cause
|
systemic symptoms, embolic events, arrthyimas, Chest pain, Heart failure.
|
|
Myxoma
|
MOST common benign cardiac TUMOR.
Accounts for 20%-30% of all intracardiac tumors. Most commonly located: LA 3X more common in LA than on the RA |
|
What is unique about knowing if a mass is myxoma ( most common presentation)
|
mass attached by a stalk to the middle of IAS - forman oval margin.
|
|
What other views can you see IAS
|
subcostal 4CH
|
|
What percent of pts myxmoas are multiple?
|
5%
|
|
Population of patients myxoma
|
young, family hx
|
|
Embolic events are moer common in -----myxoma
|
Smaller myxoma
|
|
Myxoma is slow growing but untreated its ---
|
FATAL , causes complete obstruction AV valves, NO CO if blood cant get out
|
|
Ventricular Myxoma
|
You will have LVOT obstruction
|
|
Myxoma can cause obstruction
|
prevent filling, CH won't get filled up, it can impair ventricular filling.
|
|
Myxoma pt present with
|
breathlessness, systemic emboli, fever, weakness,sudden death.
|
|
Fibroma located in
|
LV WALL, Ventricular septum, APex.
|
|
Fibroma appearance
|
See borders clearly, echogenic, multiple calcification.
|
|
Does fibroma have hemodynamic consequence
|
not really, unless it grows significantly in the LV cavity
|
|
Fibroma worry about the possibilities of
|
CONDUCTION ABNORMALITIES
|
|
Rhabdomyomas (myocardial hamartoma)
|
MOST COMMON cardiac TUmor in pediatric patients. Well circumscribed echogenic masses. Multiple mass present in the RV, RVOT, Pulmonary artery. NOT on the Left side.
|
|
Unique about Rhabdomyomas
|
commonly seen in patients with tuberous sclerosis. They can regress (shrink) when the baby is born) Spontaneously after birth
|
|
Papillary Fibroelastoma Appearance
|
Irregular shape, echogenic, mimic valvular vegetation
|
|
Most frequently originates
|
AO valve
|
|
Fear complications for Papillary Fibroelastoma
|
RISK OF emboli
|
|
if on the AO valve it can look like an anatomic variant
|
Lambls excresence
|
|
Primary Malignant tumors
|
Angiosacroma, Rhabdomyomasacroma, Fibrosacroma.
|
|
Angiosacroma located in
|
RA + Pericardial eff ] really bad
|
|
Thrombus Most common cause in the heart ?
|
Stasis of blood
|
|
What kind of situations will cause stasis of blood
|
Dilated CH, Obstruction and stagnation of blood flow, decrease Wall contractility (WMA)
|
|
3 Scenarios where you will have stasis of blood
|
Dilated CH, Decrease Contractility, Obstruction and stagnation of blood flow.
|
|
What are some diseases that can produce these types of situation
|
DOCM, POST MI, LA dilatation with severe MS, Prosthetic valves, Atrial fib- lack of atrial contraction
|
|
The wall behind the thrombus is a pt with POST MI will be
|
Diskinetic, Akinetic
|
|
Why is thrombus happening
|
Stasis of blood
|
|
most common location from thrombus is apex of LV why?
|
COMMON POST MI
|
|
Why will the wall look like behind the thrombus
|
dead, not moving, not thickening systole
|
|
if you have a tumor the wall will be
|
NORMAL
|
|
if you have thrombus the wall
|
won't be normal
|
|
If you have a patient with LV thrombus, usually the patient as
|
WA, Ventricular Aneurysm, LV Pseudo aneurysm (trauma) , DCMO
|
|
LV thrombus to form there got to be some type of
|
Dysfunction or WA
|
|
Most common cause of LA appendage thrombus
|
MS 2ndary to Rheumatic Heart disease
|
|
Why do thrombus form at the right side of the heart
|
Venous thrombi that emboli trapped on the tricuspid valve.
|
|
Iatrogenic material ( doctor put it there)
|
needles, ballons, pacemaker wire
|
|
Lipomatous Hypertrophy of Atrial septum
|
Dumbell sign, area of fossa ovals is spared.
|
|
