can somebody explain this to me? More specifically, what are they using them all for? If they end up with a right IJ, right radial, and bilateral venous sites, what are they using each site for?

I got the two....but the addition of the 2 fem lines as well...sounds like they had issues with access?

So with most ablations there are several catheters placed in the heart all at once. Most of these are for diagnostic and pacing reasons. The Right IJ is usually a 7fr sheath that is placed for a Coronary Sinus catheter. This cath is simply to see the internal electrical activity of the heart. Right radial is usually used for pressures since most patients get anesthesia. Bilateral femoral veins are usually two access sites. Right groin superior is for what is called an SLO or SRO Sheath that holds the Abaltion catheter. Right Groin Inferior is usually 7fr short sheath that introduces the a loop or lasso catheter for mapping the Left Atrium. Left Groin Superior is an SLO that holds a quad or decapolar catheter in the RV after the transeptal needle has been removed and the left inferior is a 10fr short sheath that introduces the Intra Cardiac Echo catheter or ICE.
What I explained here is a typical Atrial Fibrillation that requires so many sheaths just for one ablation. Hope this explains it.
