This a full-text version of the seminal paper from 1970:
Swan HJ, Ganz W, Forrester J, Marcus H, Diamond G, Chonette D (August 1970). "Catheterization of the heart in man with use of a flow-directed balloon-tipped catheter". N. Engl. J. Med. 283 (9): 447–51.
A manufacturer (Edwards) offers some free information about the PA catheter on their product page.
The PA catheter section from The ICU Book by Paul L Marino (3rd edition, 2007) is a valuable read.
Additionally, UpToDate has an article on PA catheter complications.
