Key result
Oxygenated Fluosol infusion during PTCA prevents the ~90% decrease in regional contraction versus controls.
Why the study?
Does transcatheter infusion of oxygenated Fluosol DA 20% prevent regional left ventricular dysfunction in patients undergoing PTCA?
Does transcatheter infusion of oxygenated Fluosol DA 20% prevent regional left ventricular dysfunction in patients undergoing PTCA?
Distal infusion of oxygenated Fluosol DA 20% during PTCA balloon inflation preserves regional left ventricular contraction, potentially allowing for longer inflation times and safer procedures in high-risk patients.

May facilitate longer PTCA inflations in high-risk cases; leaves open impact on procedural safety or outcomes.
Cleman et al. (1986) studied Myocardial ischemia during percutaneous transluminal coronary angioplasty. Transcatheter infusion of oxygenated Fluosol DA 20% vs. Control inflations (no infusion, Ringer's lactate, or nonoxygenated Fluosol DA 20%) was evaluated on Regional contraction during balloon inflation. Transcatheter infusion of oxygenated Fluosol DA 20% during PTCA maintained normal regional contraction, compared to a >90% decrease in regional contraction during control inflations.
