Coronary malperfusion requiring coronary revascularization post-aortic root replacement occurred in only 1.3% of patients undergoing Freestyle stentless bioprosthetic root replacement.
Technical improvements such as avoiding oversizing the root and extensive coronary button mobilization significantly reduced adverse coronary outcomes compared to earlier series.
Coronary artery dissection related to type A aortic dissection and concomitant coronary interventions remain important considerations in this population.
The Cabrol procedure was selectively used in 6% of patients with coronary calcification or stenosis to optimize coronary flow.
