Effect of balloon material and inflation strategy on arterial trauma and mechanisms of percutaneous transluminal coronary angioplasty as determined by intracoronary ultrasound.
Twenty-three patients were randomized to a minimally invasive strategy or to standard percutaneous transluminal coronary angioplasty followed by intracoronary ultrasound. There was no difference in intracoronary ultrasound-determined dissection after the procedure in the 2 groups, and the mechanism of lumen enlargement by percutaneous transluminal coronary angioplasty in both groups predominantly was due to vessel stretch.
