Needs clarification: It is unlikely anyone has an :intracardiac injection in their purse because there is no value to injecting medicines into the heart itself for the most part.

It is given into a muscle, often the thigh. It is easy to use, even kids learn. ...Read more
EIF: If you are referring to an 'echogenic intracardiac focus', seen in a fetus during a sonogram- then it is essentially a bright white spot, seen within a chamber of the baby's heart, having the same brightness as bone. It is considered a 'soft' marker for down's syndrome.It is present in 15-30% of fetuses that have down's syndrome, and ~5% of normal fetuses. Additional testing (amnio, harmony, mat21. ...Read more

Others can obstruct flow across valves and cause heart failure like symptoms when large enough. ...Read moreSee 1 more doctor answer
Benign finding: An eif (echocardiogenic intracardiac focus) is a common finding on fetal ultrasound. This is a small "bright" spot in the heart muscle, meaning that the spot is reflective of the ultrasound waves. The precise cause is unclear, but this finding on fetal ultrasound is not associated with any structural or functional abnormality in the baby. ...Read moreSee 1 more doctor answer

Why does intracardiac right to left shunting occur? Since the left side of heart has higher pressure, how can blood from right side flow through?
Shunt: Good observation....We see right to left shunting when the right sided pressure is higher than the left side and a connection is present between the circulations. This is when pulmonary hypertension is present. There are various causes of pulmonary hypertension including late changes in the lung from left to right shunting. ...Read more
