The clinical significance and management of patients with incomplete coronary angiography and the value of additional computed tomography coronary angiography.

HYPOTHESIS: coronary computed tomography angiography (CTA) is useful for patients with incomplete invasive coronary angiography (ICA).

METHODS: consecutive patients referred for coronary CTA after ICA, which did not visualize at least one native coronary artery or by-pass graft.

RESULTS: ICA did not identify by-pass grafts in 2% and did not identify native coronary artery in 0.2 % of cases. The explanations for an incomplete ICA included ostium anomalies, left main spasms, access site problems, ascending aorta aneurysms, and tortuous take-off of a subclavian artery. After coronary CTA, revascularization was found to be indicated in 24 % of ICA patients.

CONCLUSION: Incomplete coronary angiography is a rare, but significant clinical problem. Coronary CTA provides important clinical information in these patients.
