Bicuspid and tricuspid aortic valve repair show similar mid-term outcomes. This study suggests that a bicuspid aortic valve is not a risk factor for aortic valve repair success.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Aortic Valve Disease
Background:
- Aortic valve repair is a complex procedure.
- Understanding outcomes based on valve anatomy is crucial.
- Bicuspid aortic valves (BAV) are common congenital abnormalities.
Purpose of the Study:
- To evaluate short- and mid-term results of aortic valve repair.
- To compare outcomes between bicuspid aortic valves (BAV) and tricuspid aortic valves (TAV).
- To determine if BAV impacts aortic valve repair success.
Main Methods:
- Retrospective analysis of 100 patients with aortic regurgitation undergoing aortic valve repair.
- Patients were divided into BAV (60) and TAV (40) groups.
- Follow-up was complete in 100% with a median of 25 months.
Main Results:
- No significant difference in survival between BAV and TAV groups (p=0.102).
- Similar three-year freedom from aortic valve-related reoperation (90% vs. 89%, p=0.456).
- Comparable three-year freedom from severe aortic regurgitation (86% vs. 82%, p=0.866).
Conclusions:
- Mid-term results after aortic valve repair are similar for bicuspid and tricuspid valves.
- Bicuspid aortic valve anatomy does not appear to be a risk factor for aortic valve repair.
- These findings support the feasibility of aortic valve repair in patients with BAV.

Mitral Valve Prolapse I: Introduction
Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
