LEFT ANTERIOR DESCENDING CORONARY ARTERY (LAD) RAO or PA view Steep LAO view (40°) with severe cranial angulation (40°) for LAD and Diagonal bifurcation LAO 40°, caudal 40° (spider view) for bifurcation of LMS, proximal circumflex and LAD and at times distal LAD Spider view. Spider view - LAO (left anterior oblique) caudal view  is often the first view taken during diagnostic coronary angiography. It has the advantage of visualizing the proximal left anterior descending coronary artery (LAD) and left circumflex (LCX) coronary artery along with the left main coronary artery The LAO cranial view provides a clear view of the middle and distal segments of the left anterior descending artery and the origins of the diagonals. It also exposes the ostium of the left main coronary artery. However, the proximal segments of the left anterior descending artery is usually foreshortened thus requiring additional LAO angulation . 1 (aortic root angiography) reveals non visualization of the origin of right coronary artery and an isolated single left coronary artery.ure 1 Aortic root angiogram (LAO cranial view) Optimal Views LAO caudal and cranial; AP-caudal, cranial or flat.

of patients with coronary artery disease (CAD), the cur-rent practice of standard ﬁxed-view coronary angiogra-phy has several limitations. Studies of intravascular ul-trasound, angioscopy, and pathologic analysis have demonstrated the limited diagnostic accuracy of coronary angiography [1-7]. Standard angiography gives a ﬁxed perspective.

Primary or spontaneous coronary artery dissection (SCAD) is an unusual but increasingly recognized cause of acute myocardial ischemia and sudden cardiac death. Typically, SCAD presents in younger patients without conventional risk factors for coronary artery disease. It occurs more commonly in women than in men, and frequently during pregnancy or the postpartum period CTA was performed after elective percutaneous coronary intervention (PCI) to the distal branches of the right coronary artery (RCA) (#4:posterior lateral branch and atrio ventricular branch). a Right anterior oblique (RAO)-cranial view, b Anteroposteriol-cranial view, c Left anterior oblique (LAO)-cranial view.

There i Since it may be assumed, that the circumflex coronary artery leaves the coronary sulcus at its lowermost point (as can be seen on parasternal short axis view), the left part of the sulcus between aorta and lowermost point of the sulcus may be divided into two sections of approximately the same length, and segments of the circumflex artery.
