Abstract
Atrial fibrillation is the most common cardiac arrhythmia, leading to progressive dilation of cardiac chambers, abnormal contraction patterns of the atria and ventricles and, potentially, atrioventricular valvular insufficiency. Moreover, heart failure with preserved ejection fraction is often present and closely intertwined with disease initiation and progression. Surgical valve repair with a true-sized ring annuloplasty is a well-established treatment option in atrial functional mitral regurgitation. While early results are good, recent studies have brought the durability of this repair approach into question, highlighting the need for further refinement of the surgical strategy. In particular, repair strategies that simultaneously target the mitral valve as well as the left ventricle could provide improved repair durability.
