projection angle

Its is indeed 'Anl*o*ten'. This term is somehow misapplied here. It is more commonly used in cardiac ultrasound/echocardiography rather than cardiac CT and/or angiography. Literally akin 'sounding'.

It means the angle (of the ultrasound probe) which is optimal for imaging of certain anatomic structures. Here it obviously refers to the tilt of the CT gantry or the angle of the X-ray tube.

Note that in the LAO projection ventricular and atrial structures cannot be distinguished. In most hearts, an LAO *projection angle' of approximately 30° will align along the interventricular septum.

Many possible *projection angles* can correctly represent the native aortic valve plane in a given patient....
However, to more accurately determine the valve plane, multiple orthogonal aortic root angiograms can be performed until an angiographic *projection angle* is found in which the base of all aortic valve cusps/sinuses of Valsalva are on a straight line.

Accurate device positioning in Transcatheter Aortic Valve Replacement (TAVR) requires an angiographic *projection angle* perpendicular to the native valve plane.

anatomic*al* instead of *anatomic*, apologies...
Note from asker:
Great, you saved me. I had no clue at all.

This should be anloetungswinkel (umlaut); there are various errors in your text, it must have been scanned.

Dear pj-ffm: This word certainly appears frequently in the literature for a word that does not exist...
Peer comment(s):

disagree uyuni : Never (!) apply solder to the aortic valve or the coronary arteries... ;-) //edit: I would not dare to perform left heart catheterization with a previously 'soldered' catheter. So, to use one of SJLD's favourite phrases: 'Don't try this at home!' ;-))

the catheter is soldered, not the artery!!!
disagree pj-ffm : Not in cardiology... Sorry, "Anlötungswinkel" is not a word and this is clearly describing the optimal angiographic projection angle.
