"Reverse Spider View" for left stem coronary artery angiographic evaluation.

Area of Science:

• Cardiovascular Imaging
• Interventional Cardiology
• Radiology

Background:

• The spider view is iconic for evaluating left coronary artery systems, especially the Left Main (LM) stem and bifurcations.
• Its use in percutaneous coronary interventions (PCIs) for LM bifurcation disease is significant.
• However, the spider view involves high X-ray exposure for operators and patients.

Purpose of the Study:

• To introduce and describe an alternative angiographic view, the "reverse spider" view.
• To demonstrate its utility in evaluating LM body and bifurcation disease.
• To highlight its advantage in reducing X-ray exposure.

Main Methods:

• Description of the novel "reverse spider" angiographic view.
• Comparison of the reverse spider view with the traditional spider view.
• Assessment of information provided regarding LM and bifurcation disease.

Main Results:

• The reverse spider view provides valuable information on LM body and bifurcation disease.
• This alternative view potentially reduces X-ray exposure compared to the spider view.
• It offers an improved method for assessing complex LM lesions.

Conclusions:

• The reverse spider view is a viable alternative to the traditional spider view.
• It enhances the evaluation of LM and bifurcation disease.
• It offers a safer approach with reduced radiation exposure in coronary angiography.
