Key result
Preoperative 3D-CTA detected asymptomatic coronary stenosis in 40.8% of lung cancer patients, identifying severe disease requiring intervention that could not be judged solely by conventional CT.

Does 3D-CTA improve the preoperative detection of coronary artery disease in elderly lung cancer patients compared to conventional CT?
3D-CTA is a useful preoperative screening tool that detects clinically significant coronary artery disease missed by conventional CT in elderly patients undergoing lung cancer surgery.

May aid preoperative CAD detection beyond conventional CT in lung cancer patients; leaves open whether routine use improves outcomes.
BACKGROUND: The number of elderly patients undergoing surgery for lung cancer is increasing. In this study, we assessed the usefulness of three-dimensional computed tomographicangiography (3D-CTA) for the detection of coronary disease in the elderly before surgical intervention for lung cancer. METHODS: One hundred twenty patients admitted to our institution for lung cancer resection were enrolled in the study. 3D-CTA was performed in all 120 patients. RESULTS: Seventy-one patients had normal findings, and forty-nine patients showed coronary stenosis on 3D-CTA examination. Among the latter 49 patients, 24 with slight stenosis underwent lung tumor resection, 23 had coronary angiography for severe stenosis before lung surgery and 2 were not eligible for lung resection because of very severe coronary stenosis. The diagnostic value of 3D-CTA was better than conventional CT. CONCLUSIONS: This study suggests the usefulness of 3D-CTA for the preoperative diagnosis of coronary ischemic disease in elderly lung cancer patients.

Watanabe et al. (2013) conducted an observational in Lung cancer (n=120). Three-dimensional computed tomographic angiography (3D-CTA) vs. Conventional CT was evaluated on Detection of coronary stenosis. Preoperative 3D-CTA detected asymptomatic coronary stenosis in 40.8% of lung cancer patients, identifying severe disease requiring intervention that could not be judged solely by conventional CT.
