What does bilateral ostia seen mean?

"Bilateral ostia seen" typically refers to the observation of two openings or passageways on both sides of a structure, often in a medical imaging or anatomical context. This term can be relevant in various fields, such as cardiology, where it might describe the presence of ostia (openings) for blood vessels or valves. The bilateral nature indicates that these openings are symmetric and located on both sides of the body or organ in question. Understanding this can be crucial for diagnosing conditions or planning surgical interventions.
