TTE (Panels A and B) and TEE (Panels C and D) visualization of the aortic dissection. (A) Long-axis parasternal view, notice the enlarged aorta (arrow) measuring up to 5 cm at the distal aortic root. (B) Doppler mode showing noticeable backflow at the aortic valve during diastole, indicating aortic regurgitation (arrow). (C) Incomplete closing of the valve (dotted circle) during diastole causing aortic regurgitation, secondary to dilated aortic root. (D) False lumen space (arrow) separated by the torn endothelium. Other findings include normal ejection fraction, eccentric left ventricular hypertrophy, and absence of pericardial effusion.
