ABSTRACT
OBJECTIVES:
We propose a right lateral (90-120° RAO) with 30° cranial angiographic view to expose the bifurcation of the left main coronary artery (LMCA) when previously used routine projections were inefficient at clearly showing this region.BACKGROUND:
Little has been published in the medical literature regarding angiographic projections dedicated to special anatomies.METHODS:
A total of 84 patients were subjected to the proposed projections. A reproducibility study, conducted with the participation of 2 independent observers, judged the effectiveness of the proposed projection. The Prevalence and Bias Adjusted Kappa (PABAK) index, with a 95% confidence interval (CI), was used to demonstrate the intensity of intra/inter-observer agreement.RESULTS:
The proposed projection was efficient in 79% of the angiograms, with agreement of 0.76 (0.6-0.9; P ≤ 0.001). The origins and the proximal segments of the anterior descending coronary artery were exposed in 89% of the angiograms, agreement of 0.86 (0.7-1.0; P ≤ 0.001); the circumflex artery were exposed in 83% of the angiograms, with agreement of 0.72 (0.5-1.0; P ≤ 0.001); and the intermediate branch, when present, were exposed in 89% of the angiograms, agreement of 0.79 (0.6-1.0; P ≤ 0.001).CONCLUSION:
The right lateral (90-120° RAO) with 30° cranial projection is effective, safe, and reproducible. In special situations where routine projections fail, this proposed projection can reveal important details of the anatomy of the bifurcation of the LMCA during conventional coronary angiography or be the working projection during coronary angioplasty.
