Key result
Predictors of aortic valve repair failure include unaddressed annular dilation, residual cusp prolapse or retraction, commissural orientation, and use of patch material.
Why the study?
Recurrent aortic insufficiency is the major complication of aortic valve repair, prompting a review of the current knowledge on predictors of repair failure.
What are the predictors of aortic valve repair failure in patients with severe aortic insufficiency?
What are the predictors of aortic valve repair failure in patients with severe aortic insufficiency?
Understanding predictors of aortic valve repair failure, such as unaddressed annular dilation and residual cusp prolapse, can help refine surgical techniques and improve patient outcomes.
Intraoperative attention to these predictors may improve aortic valve repair durability; leaves open need for prospective validation before practice change.
Aortic valve repair is the preferred approach for the treatment of severe aortic insufficiency (AI), as it allows patients to keep their native aortic valve, thus substantially reducing the risk of prosthesis-related complications. Several studies have documented excellent long-term outcomes of aortic valve repair. The major complication of this operation is AI recurrence, with ensuingneed for reoperation. The surgical experience accumulated over the last two decades has allowed for better understanding of the mechanisms of recurrent AI after aortic valve repair. Herein, we review the current state of knowledge on predictors of aortic valve repair failure. These include unaddressed annular dilation, residual cusp prolapse or retraction, commissural orientation, and use of patch material. This enhanced understanding has led to the development of increasingly refined techniques and improved patient outcomes. Continued follow-up and detailed data collection at the time of surgery, together with three-dimensional echo imaging, will allow further improvements in aortic valve repair.

Yanagawa et al. (2019) conducted a review in Severe aortic insufficiency. Predictors of aortic valve repair failure was evaluated on Aortic valve repair failure (AI recurrence). Predictors of aortic valve repair failure include unaddressed annular dilation, residual cusp prolapse or retraction, commissural orientation, and use of patch material.
