Key result
Well-collimated AP and shallow RAO/LAO views best visualize the LMCA without foreshortening versus routine projections.
Why the study?
Diagnosis of significant left main coronary artery stenosis by clinical grounds is inconsistent and requires angiography, but routine projections cause foreshortening of the artery.
Do well-collimated anteroposterior and shallow right and left anterior oblique views improve visualization of the left main coronary artery compared to routine projections?

May guide projection choice in arteriography; leaves open prospective validation of diagnostic impact.
Do well-collimated anteroposterior and shallow right and left anterior oblique views improve visualization of the left main coronary artery compared to routine projections?
Anteroposterior and shallow right and left anterior oblique views are essential during coronary arteriography to accurately assess the left main coronary artery.
Nath et al. (1979) studied Left main coronary artery stenosis. Anteroposterior and shallow right and left anterior oblique views vs. Routine projections was evaluated on Visualization of the left main coronary artery without foreshortening. Well-collimated anteroposterior and shallow right and left anterior oblique views best demonstrate the left main coronary artery without foreshortening compared to routine projections.
