Would a cardiac cath show if i have a tortuous course of the thoracic aorata?

Yes, a cardiac catheterization (cardiac cath) can provide information about the anatomy of the thoracic aorta, including any tortuous courses. During the procedure, contrast dye is injected, allowing for imaging that can reveal abnormalities in the aorta's shape and structure. However, other imaging modalities like echocardiography, CT angiography, or MRI might be more commonly used to assess the aorta's morphology in detail. It's best to discuss with your healthcare provider which imaging technique is most appropriate for your situation.
