Diagnosis of this TTE?! 👀 (Don’t cheat — try to spot it before reading on!) Chest trauma? 👉 Watch for the flap. A thin, mobile, linear echo within the aortic lumen = possible intimal tear — a red flag for aortic injury or dissection. Echo Tips for Evaluation: 🔹 Scan in multiple views to confirm mobility and continuity 🔹 Use color Doppler to distinguish true (original) vs false (new) lumen 🔹 Quantify aortic regurgitation 🔹 Check for pericardial effusion — may signal rupture and impending ta
