23 Three year review of mitral valve surgery: predictability of mitral valve repair

Abstract

Aims We aim to outline a three year review of consecutive mitral valve surgeries performed by a single surgeon. We further aim to establish the predictability of mitral valve repair in the degenerative population. Methods All patients who underwent isolated or combined mitral valve surgery from January 2013 to April 2016 had their pre operative echocardiograph and their operative note reviewed. In cases of degenerative disease this data was reviewed to compare predicted repair rates to actual repair rates. Results 181 patients underwent mitral valve surgery. Underlying pathologies were as follows; degenerative 57% (n = 103), functional/ischaemic 18.2% (n = 33), rheumatic 13.3% (n = 24), previous endocarditis 7.1% (n = 13), revision mitral valve surgery 4.4% (n = 8) and systolic anterior motion of the mitral valve 0.6% (n = 1). 78.5% (n = 142) of patients underwent mitral valve repair and 21.5% (n = 39) of patients underwent mitral valve replacement. 99.02% (n = 141) of patients with degenerative disease underwent a successful repair and 0.08% underwent mitral valve replacement. Conclusion Degenerative mitral valve disease remains the most common underlying pathology requiring mitral valve surgery. In high volume services, excellent repair rates can be achieved. This serves to further support the role of mitral valve surgery in patients with asymptomatic mitral valve disease.
