Long-term changes in left ventricular performance following mitral valve replacement for pure rheumatic mitral regurgitation.
Our data indicate that MVR, with or without chordal preservation, for pure severe MR in symptomatic younger rheumatic patients with a good preoperative ejection fraction results in normalization of LV size and performance by 1 year. Normalization of LV performance was only achieved at 1 year after surgery, and it is therefore essential to extend the assessment of LV function to at least 1 year postoperatively.
