I work for a group cardiology practice. There are a couple of Dr's that always document in their cath report "_____catheter was use for the left ventriculogram" or "hand injections RAO left ventriculogram was preformed" I am not sure if this is sufficient documentation. Isn't it necessary to state in the report that they entered the left ventricile or accessed the left ventricle. It is my understanding that is what is necessary to distinguish between a Left heart cath and an angio. Does anyone know of any published documentation guidelines?
