Imaging: Cardiovascular Imaging II Flashcards
What is the Hampton hump?
- Westermark sign: focal peripheral hyperlucency secondary to oligemia resulting in a collapsed appearance of vessels distal to the occlusion.
How is chest x-ray used in acute pulmonary embolism?
What do you see here?
What is shown here?
Where are the aortic and mitral valves here?
What kind of pacemaker is described?
- Has at least one right ventricular lead, one left ventricular lead and may have a right atrial lead as well.
- The left ventricular lead traverses the coronary sinus into a posterior or lateral cardiac vein
- This allows access to the lateral left ventricle wall for left ventricular pacing.
What is shown at the arrow?

What is shown here?
Saddle Embolism: When it goes over bifurcation of pulmonary artery
What condition caused this? (the white arrow?)
Name the Pacemaker/ICD Complication
Name the Pacemaker/ICD Complication
What is shown at the arrow?
eccentric clot
What device is described?
- Capable of generating a large amount of electrical energy in a single output used to defibrillate the heart.
- If the device senses a tachyarrhythmia such as ventricular tachycardia or ventricular fibrillation, it sends a defibrillation shock to cardiovert the heart.
What kind of pacemaker is this?
Single Lead Ventricular Pacemaker VVI
What is the Palla sign?
- enlargement of the descending interlobar branch of the right pulmonary artery, causing a “sausage” appearance towards right middle lobe.
What device is shown?
What is wrong with this?
Misplaced lead
What are the features of right heart strain from pulmonary embolism?
What pacemaker is described?
- Has one lead that paces either the right ventricle or right atrium.
- Most commonly, this lead is placed in the apex of the right ventricle
- Used to pace the heart when there is a problem with the conduction pathways.
What is the Checklist for CIED Evaluation

What is Twiddler Syndrome?

What is the Westermark sign?
What are the arrows pointing to?
Hilar adenopathy
What is shown?

Name the Pacemaker/ICD Complication
What is a Fleischner sign?
a disproportionately enlarged left pulmonary artery
What kind of pacemaker is described?
- Has leads in the right atrium and right ventricle.
- This type of pacemaker helps coordinate signals to and contractions of the atria and ventricles.
