Limiting coronary malperfusion in bioprosthetic aortic root replacement

The authors aimed to evaluate the incidence of coronary malperfusion following Freestyle aortic root replacement and to identify techniques that can limit this complication. They found a low incidence of coronary malperfusion at 1.3%, with improvements in surgical techniques contributing to reduced adverse outcomes. The study suggests that bioprosthetic aortic root replacement can be performed safely and effectively when specific techniques are employed.
