Dear John,
I usually perform Picrosirius Red stain in cardiac tisse sections.
I use phosphomolibic acid treatment in order to eliminate the cytoplasmic
staining improving collagen/myoplasm contrast.

Have a look at this paper:
Picrosirius red staining of cardiac muscle following phosphomolybdic acid
Dolber PC, Spach MS
Stain Technol. 1987 Jan;62(1):23-6.

Good luck!
