pulmonary---systemic flow ratio (Qp/Qs): What it is how to calculate it
A high Qp/Qs ratio The ratio of pul-monary blood flow (Qp) to systemic blood flow (Qs) can be calculated as: In PFO blood can flow only from right to left FIGURE 2 Color Doppler transesophageal echocardiogram images comparing a patent foramen ovale (left image) and secundum atrial septal defect (right image) In the left
What is a normal Qp/Qs ratio?
flow, the Qp/Qs ratio, is a useful tool for quantifying the net shunt.AQp/Qsratioof1:1is normal and usually indicates that there is no shunting. A Qp/Qs ratio of 1:1 indicates that pulmonary flow exceeds systemic flow and defines a net left-to-right shunt. Similarly, a Qp/Qs ratio of 1:1 indicates a net right-to-left shunt.
What is the AUC of Qp/Qs ratio?
threshold of a Qp/Qs ratio >1.75:1 (area under curve (AUC) 5 0.99). Quantification of left-to-right shunting can be performed reliably and accurately by PC-MRI and the data
What is the Qp/Qs ratio for right shunting?
right shunting based on measurements of blood oxyge- nation [5–7]. Interventional closure or corrective surgery is usually indicated in patients with a Qp/Qs ratio >1.5. MRI is a non-invasive method that allows an exact visualisation of cardiac anatomy and an accurate non-
What is Qp and QS in echocardiography?
Quantification of shunt volumes and of the ratio of flow in the pulmonary (Qp) and systemic circulation (Qs) and assessment of cardiac dilatation as a consequence of volume overload are crucial in the management of patients with left-to-right shunting [1–3]. Transthoracic and transoesophageal echocardiography usually allow exact localisation and
