Lecture 17: heart Flashcards
which of the following is a more appropriate radiograph
Upper left- inspiration- more space between heart and diaphragm
Lower right: exhalation- not as much space
t or f: use the spine to determine left and right heart
false
on rads it is easier to see __ hypertrophy vs __
eccentric, concentric
which represents normal, concentric vs eccentric hypertrophy
Left: eccentric hypertrophy- chamber dilation and thin walls
Middle: normal
Right: concentric hypertrophy- thick walls, thin chamber
what two ddx
pericardial effusion or eccentric hypertrophy (DCM)
think of heart as clock what is located at 12, 1-2, 2-3, between 3-6, between 6-10 and 10–12
12: aorta
1-2: pulmonary artery
2-3: left atrium
3-6: left ventricle
6-10: right ventricle
10-12: right atrium
what wrong
left atrial enlargement
reverse D, right ventricle enlargement usually __ or severe __hypertrophy
eccentric, concentric
what are two differentials for reverse D (right ventricle enlargement) what are age ranges for each
- Pulmonic stenosis <2yrs
- Heartworm dz >4yrs
X-ray of puppy, what is likely dx. What about dog >4y
puppy: pulmonic stenosis
>4y: heartworm disease
if your have large pulmonary artery what is likely problem
pulmonary hypertension
if you have large pulmonary vein what is likely problem
left sided heart failure
if both pulmonary artery and pulmonary veins are enlarged what wrong
PDA
what are some signs of heartworm disease on xray
- Reverse D
- Large pulmonary artery
- Tortus
- Bronchointerstitial lung pattern
taken from 5yr old dog, identify 1+ 3, lung pattern and what is likely dx
- Pulmonary artery (enlarged)
- Pulmonary vein
Lung pattern: interstitial
Dx: heartworm disease
identify 1-2, based on x-ray what is likely dx . Which lobe is affected
- Pulmonary artery
- Pulmonary vein (enlarged)
Dx: left sided heart failure
Right caudal lung lobe affected
puppy X-ray- what likely dx, identify 1-2
Dx: PDA (both artery and vein enlarged)
1. Artery
2. Vein
puppy presented in respiratory distress and burn marks on tongue, based on this x-ray what is dx and cause
Caudodorsal lung pattern
Cardiac silhouette looks good
Likely noncardiogenic pulmonary edema, electrocution consistent with burns on tongue and lung pattern
1 month old leonberger presented with distress and lethargy. What wrong
peritoneal-pericardial diaphragmatic hernia
