Key result
Doppler ultrasound mapping of the ascending aorta in patients with normal valves showed a skewed peak systolic velocity profile with the highest velocity along the left posterior wall.
Why the study?
What is the distribution of blood velocities across the human ascending aorta, and what is the optimal sampling site for measuring cardiac output?
Population

What is the distribution of blood velocities across the human ascending aorta, and what is the optimal sampling site for measuring cardiac output?
The study maps the complex, skewed blood velocity profiles in the human ascending aorta and identifies the optimal Doppler sampling site for estimating cardiac output.
Segadal et al. (1987) conducted an observational in Patients undergoing open-heart surgery (n=8). Doppler ultrasound mapping of blood velocities was evaluated on Blood velocity distribution in the ascending aorta. Doppler ultrasound mapping of the ascending aorta in patients with normal valves showed a skewed peak systolic velocity profile with the highest velocity along the left posterior wall.
