Spider view – Cardiology MCQ

Correct answer: a) LAO caudal view
LAO (left anterior oblique) caudal view, also known as spider view, is often the first view taken during diagnostic coronary angiography. Some operators prefer to take RAO caudal view as the first shot. Both these caudal views are useful in delineating the left main coronary artery and its proximal branches. As those with critical proximal coronary artery disease can potentially deteriorate fast even during angiography, it is vital to detect these lesions early in the course of the procedure.
