Risk factors and clinical significance of elevated mitral valve gradient following valve repair for degenerative disease.

ABSTRACT:

Objectives

The risk factors and clinical effect of elevated mitral valve (MV) gradients after valve repair for degenerative valve disease remain insufficiently understood.

Methods

Between January 2004 and December 2015, a total of 484 patients underwent valve repair for degenerative disease. A true-sized full annuloplasty ring was implanted in all cases. We analysed the effect of preoperative and intraoperative factors on the postrepair gradient. Additionally, we explored the effect of postrepair gradients on long-term outcomes.

Results

On linear regression analysis, postrepair MV gradients were associated with patient age (coefficient = -0.110, standard error = 0.005, P = 0.034), body surface area (coefficient = 0.905, standard error = 0.340, P = 0.008), implanted an
