Coronary Vessels (Anatomy and Pathology) [24%] Flashcards
This artery defines the transition from proximal and mid LAD.
Septal perforator 1.
Defines the transition between proximal and mid RCA
AV groove and diaphragmatic surface.
3 general types of coronary anomalies
Abnormal origin
Abnormal course
Abnormal termination (fistula)
5 types of ACAOS
- Retrocardiac
- Retroaortic
- Preaortic
- Intraseptal (supracristal)
- Prepulmonary (precardiac)
ACAOS. Definition ?
Anomalous Coronary Artery from the Opposite Sinus
ALCAPA
Anomalous Coronary Artery from Pulmonary Artery
The direction of flow is reversed in LAD.
Sinoatrial Artery
This seems like a good anatomic structure to be pointed to. (need a picture)
Coronary Artery aneurysm
This seems like a good anatomic structure.
Like Kawasaki -
Myocardial Bridge
This would be a good anatomic picture.
Common. Typically is asymptomatic.
coronary artery to PA fistula
This would be a good anatomic picture.
Most people are asymptomatic
SIS score with decreased survival
Min et al. 2007 SIS >5.
important thing is that a single plaque is probably not all that bad.
In Rixe et al 2006, the stent diameter which was associated with a significantly reduced ability to evaluate the stent lumen ?
<3mm
2 huge dilated coronary artery grafts
good anatomic picture to use.
lipomatous hypertrophy of interatrial septum
good picture
This is a benign condition
Picture of a darkenening in Left atrial appendage in pt with AF. What to do next?
Possible LAA thrombus. PERFORM DELAYED SCAN.
Secundum ASD picture
Good anatomic picture to identify.
Sinus Venosus ASD
good picture. High up picture, connecting.
Look for Superior or Inferior Sinus Venosus ASD
Persistent Ductus Arteriosis
Good anatomic picture.
Diastolic phase picture of gap for AI
good anatomic picture
for AI
Hockey stick MV
good anatomic picture for mitral stneosis
Prosthetic valve showing dehiscence and abscess
good anatomic picture
Picture of 4 chamber which looks like MVP
Reformat the data
Tricker - may not see in other views.
CTA reports says CADRADS3. What is next step is suggested if any.
Consider functional assessment
CADRADS criteria for vulnerable plaque
.1. Low CT density 30 HU
- Spotty calcification - punctate calc in noncalc lesion
- Napkin ring sign
- Positive Remodeling
NXT Trial, PPV and NPV of FFR-CT?
65 and 95
Most important is that FFRCT increases Accruracy while maintaining NPV
Beam hardening artifact in perfusion image
good image and question.
Clue is next to a HIGH ATTENUATION STRUCTURE (such as spine or descending aorta)
Aorta showing Beak Sign of false lumen of dissection
Good picture
