A new method removes guidewire artifacts in optical coherence tomography, enabling visualization of a rare spiral dissection in the radial artery after coronary intervention.
Area of Science:
- Cardiovascular Imaging
- Interventional Cardiology
- Optical Coherence Tomography
Background:
- Guidewire shadow artifacts can obscure critical details during in vivo optical coherence tomography (OCT) interpretation.
- Transradial coronary intervention is a common procedure, but potential complications require careful monitoring.
Observation:
- A novel technique successfully eliminated guidewire artifacts in frequent domain OCT.
- This artifact removal facilitated the clear visualization of an iatrogenic spiral dissection of the radial artery.
Findings:
- The study identified a rare complication: spiral dissection of the radial artery.
- This dissection was directly linked to the transradial coronary intervention procedure.
Implications:
- Improved OCT interpretation can enhance the detection of rare iatrogenic vascular injuries.
- This technique may refine procedural safety and patient outcomes in interventional cardiology.

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
