Which of the following is a key feature that distinguishes OCT from other intracoronary imaging modalities, such as intravascular ultrasound (IVUS)?
OCT can only visualize soft plaques.
OCT provides higher resolution images.
IVUS is better at assessing vessel dimensions.
OCT cannot be used in calcified lesions.
OCT eliminates the need for contrast agents.
What is the primary imaging principle behind Optical Coherence Tomography (OCT)?
X-ray absorption
Light interference
Magnetic resonance
Ultrasound reflection
In the context calcified plaque imaging, what component of OCT analysis that differentiate OCT with IVUS?
Angle of calcium
Calcium length
Vessel diameter
Maximal calcium thickness
Calcified nodule
Which type of calcification morphology is not identified with OCT
Thin
Superficial
Deep
Nodular
What component of OCT analysis that should be acquired after PCI procedure
Plaque morphology
Lesion length
Vessel diameter
Stent apposition
Intimal dissection
Which of the following statements about orbital atherectomy is TRUE?
It is ineffective in treating heavily calcified lesions.
It utilizes a centrifugal rotating burr to modify plaque morphology.
It is a pharmacological approach to dissolve calcified plaque.
It is contraindicated for use in patients with diabetes.
Its calcium modification property is done by forward only motion
The primary objectives with coronary orbital atherectomy are, EXCEPT?
Reduction severe calcium to help optimize stent outcomes
Orbital atherectomy reduces long-term survival
Minimum stent area (MSA) is a strong predictor of long-term restenosis, TVR, and stent thrombosis
Complete stent apposition facilitates uniform drug delivery and reduction of TLR
What is a common complication associated with orbital atherectomy?
Hematoma formation
Artery perforation
Stent thrombosis
Myocardial infarction
Distal embolization of debris
The rule of 5's in OCT calcium scoring is based on these factors, EXCEPT
Maximum calcium thickness
Calcium length
Nodular calcification
Maximum calcium arc
This is true about traverse speed in orbital atherectomy
Slower traverse speeds provide more control and efficiency during treatment and can help prevent complications
Slower traverse speeds extend treatment times
Faster traverse is safer when using high speed
The traverse speed does not matter when performing orbital atherectomy
