Atrial septal defect (ASD) is a heart defect that is present at birth (congenital). While the baby is in the womb, there is normally an opening between the upper chambers of the heart (atria) to allow blood to flow around the lungs. This opening usually closes around the time when the baby is born.
Atherectomy – A nonsurgical technique for treating diseased arteries with a rotating device that cuts or shaves away material that is blocking or narrowing an artery.
Ultrasound-Guided Vascular Access: In-Plane Approach
The in-plane or long access approach is the technique used to allow visualization of the entire needle when performing ultrasound-guided vascular access.
The transducer is positioned in a long axis over the selected vein. The vessel is visualized straight across the screen. The needle is placed at the center of the transducer in-line with the ultrasound beam and the trajectory of the vessel with the bevel up.
The transducer is held stationary with the non-dominant hand while advancing the needle using the dominant hand.

A blood clot (thrombus) in a deep vein in the thigh or leg. The clot can break off as an embolus and make its way to the lung, where it can cause respiratory distress and respiratory failure.
