Abstract
Comparing the right-sided cardiac output and left-sided cardiac output is important in situations where a shunt is suspected; it is done by comparing the flow across the LVOT and the RVOT. It is important to remember the limitations and the pitfalls of this technique, as well as to understand precisely the information obtained from these calculations. PDA is a unique example where the classic comparison of the LVOT and RVOT cardiac output results in “confusing” data. Since PDA is an abnormal communication between the right and the left heart occurring outside the heart, it is important to understand which site (LVOT / RVOT) represents which circulation.
