Lordotic right posterior oblique projection of the left coronary artery: a speical view for special anatomy.
Key result
Lordotic RPO projection improves LCA visualization while adding under ~2 minutes to procedure time.
Why the study?
The lordotic right posterior oblique projection improves arteriographic assessment of the left coronary artery, especially when the LAD artery is directed cephalad early in its course.
Does the lordotic right posterior oblique projection improve arteriographic assessment of the left coronary artery?
Population
Patients undergoing coronary angiography, especially with early cephalad LAD direction

Implication
May aid visualization in select left coronary cases; leaves open need for prospective validation before routine use.
Structured PICO
Does the lordotic right posterior oblique projection improve arteriographic assessment of the left coronary artery?
P
Population
Patients undergoing coronary angiography, especially those in whom the left anterior descending artery is directed cephalad early in its course
I
Intervention
Lordotic right posterior oblique projection (combining cranial angulation of the X-ray beam with rotation of the patient into the right posterior oblique position)
O
Outcome
Separation of the main left coronary artery and the proximal portions of the left anterior descending and circumflex divisionssurrogate
The lordotic right posterior oblique projection is a useful angiographic technique for better visualizing the proximal left coronary system, particularly when the LAD has an early cephalad course.
Cite This Study
Arani et al. (1975) studied Coronary artery anatomy assessment. Lordotic right posterior oblique projection was evaluated on Arteriographic assessment improvement and procedure time. The lordotic right posterior oblique projection improves arteriographic assessment of the left coronary artery, adding less than two minutes to the procedure.
