In vivo coronary angioscopy utilizing a 1.8 mm angioscope was demonstrated to be feasible for direct visualization of intravascular anatomy in patients during open heart surgery.
Is in vivo coronary angioscopy feasible for direct visualization of intravascular anatomy?
This early study demonstrates the feasibility of using a 1.8 mm angioscope with optically clear liquids for direct in vivo visualization of coronary intravascular anatomy.
The feasibility of in vivo coronary angioscopy was tested utilizing a 1.8 mm angioscope in vessels where blood had been replaced by optically clear liquids, including a new perfluorocarbon emulsion. After trials in postmortem canine and human coronary arteries, in vivo intraluminal visualization was accomplished in the dog with a catheterization technique and in patients during open heart surgery. The results demonstrate the feasibility and potential clinical usefulness of direct visualization of intravascular anatomy and disease, analogous to endoscopy of other organ systems.
