Case Report (n=1)
Undersized mitral ring annuloplasty can lead to complete prolapse of both mitral leaflets, severe mitral regurgitation, and subsequent giant left atrium.

Reoperation may reverse giant left atrium after undersized annuloplasty; leaves open need for prospective data on this complication.
Enlargement of left atrium occurs in patients with longstanding mitral valve disease due to chronic pressure and volume overload and occasionally left atrium reaches a massive enlargement, condition known as giant left atrium. It is most commonly associated with rheumatic mitral valve disease, both stenosis and regurgitation. This unique case deals with a 70-year-old woman who developed a giant left atrium due to a severe mitral regurgitation from complete prolapse of both mitral leaflets, as a consequence of previous undersized mitral ring annuloplasty.

Bertin et al. (2016) conducted a case report in Giant left atrium and severe mitral regurgitation (n=1). Mitral valve replacement and tricuspid valve repair was evaluated on Left atrial volume and valve function.
