Where can I find the pathway of coronary catheterization from the hand to the coronary arteries?[edit]
Where can I find the pathway of coronary catheterization from the hand to the coronary arteries? I'd like to know the way in details, by any vessel that the cath insert till it comes to the coronary arteries. I found a way on internet that by the aorta arch, and from this place it's not understood how it enters to the coronary artery, what's the place that the cath enters to the coronary arteries).

- (Radial artery) > brachial artery > axillary artery > subclavian artery > (brachiocephalic artery, right only) > aortic arch > coronary arteries. I got that by following the "source" entries in the infoboxes. The other, more frequently-used insertion point for percutaneous coronary intervention is one of the femoral arteries in the leg. --47.146.63.87 (talk) 00:30, 15 September 2019 (UTC)
- If the question is specifically the entry to the coronary arteries proper, the left and right coronary arteries are supplied by their respective coronary ostia, just above the aortic valve. The aortic valve has three cusps: one, called the non-coronary cusp, has no ostia; the right coronary cusp, whose ostia supplies the right coronary artery; and the left coronary cusp, which supplies the left (main) coronary artery. If you look at our article aortic sinus you can see an illustration of where the ostia are, labelled "origins of coroner arteries" -Nunh-huh 13:36, 15 September 2019 (UTC)
