Ultrasonic annular debridement in minimally invasive aortic valve replacement.

Here, we demonstrate the details of annular decalcification using an ultrasonic aspirator in minimally invasive aortic valve replacement for aortic stenosis. In our debridement procedure, the aortic valve leaflets are excised with enough valve tissue left, not just at the annulus. The invisible annulus is exposed by traction of the remnant valve tissue, and the annular calcifications are scraped off using an ultrasonic aspirator. After an annular decalcification, the remnant valve tissue was completely resected using long scissors. No cases of in-hospital mortality, annular injury, stroke, or paravalvular leakage were found. In conclusion, ultrasonic aspirator allowed safe and secure annular debridement and could be a useful tool during minimally invasive aortic valve replacement.
