Abstract
The effectiveness of posterior annuloplasty in two patients who failed to respond to medical treatment for atrial and ventricular arrhythmias related to mitral valve prolapse (MVP) is reported. Although the etiology of arrhythmia in MVP remains mostly speculative, anatomic correction of prolapse or billowing of the mitral leaflets appears to reverse the anatomic and pathologic conditions that cause the arrhythmia.
