Cardiac masses, afib, pulm disease Flashcards
tumor originating from right atrium
angiosarcoma
Least likely place for myxoma
valvular origins
most common malignant tumor of heart
metastatic is most common
(angiosarcoma most common of sarcomas)
greatest propensity for metastasis to heart
melanoma (50% chance)
benign primary tumors
more common than malignant
myxomas
lipomas
papillary fibroelastomas
myxomas
most common benign primary tumor
typically middle aged adults women >men
majority are in LA
mobile ,irregular and pedunculated, often attached to fossa ovalis
usually do not recur
lipomas
anywhere in heart but more common in subpericardial/extramyocardial
Lipomatous hypertrophy most commonly of interatrial septum (watersons groove/superior interatrial groove accumulation of fat)
fibroelastomas
Usually on ventricular side of MV and aortic side of AV
appears like vegetation or lambls excresence
well demarcated, can have mobile stalk, usually less than 2 cm
can embolize causing stroke/MI
primary Malignant tumors
sarcomas
lymphomas
Types of sarcoma
angiosarcomas - more common, middle age men, predilection for RA, poorly defined borders
rhabdomyosarcoma- more common in kids, usually in ventricular wall
Secondary cardiac tumors
Much more common than primary tumors
Most often from lung, breast, melanoma, leukemia/lymphoma
often involve pericardium
Pericardial effusion most common finding in metastatic disease
Mass in IVC
often RCC, growing into RA
malignant melanoma
uncommon but seen on pericardial surface (charcoal heart)
what is v wave cutoff
early peak velocity and steep decline seen on CWD of insufficient jet (Severe TR) rather than parabolic shape
