- W2416441396 abstract "Background Dilated cardiomyopathy (DCM) is often complicated by the appearance of functional mitral regurgitation (FMR). Although mitral ring annuloplasty (MAP) is the most widely used surgical procedure for the surgical treatment of FMR, there are still reports of patients who suff er recurrent FMR at later follow-ups. We sought to investigate the effi cacy of papillary muscle approximation (PMA) combined with MAP in preventing the recurrence of FMR in high-risk patients.Methods One hundred patients with ischaemic (74%) or non-ischaemic (26%) DCM along with severe (4+/4+) or moderately severe (3+/4+) FMR were enrolled in this prospective, cross-sectional study. According to the interpapillary muscle distance (iPMD) and coaptation depth (CD), the patients were risk stratifi ed as low (iPMD + CD ≤ 30 mm, n = 69) and high-risk (iPMD + CD > 30 mm, n = 31) groups. The low-risk patients underwent only MAP, whereas the high-risk patients underwent MAP plus PMA.Results After a mean ± SD follow-up of 40.8 ± 12.5 months, recurrence of 3+ to 4+ MR was observed in 8 (8.7%) and 7 (11.1%) patients in the annuloplasty group (MAP-only) and one (3.4%) patient in the combination group (MAP plus PMA) (P = 0.428). At the fi nal follow-up, the New York Heart Association (NYHA) function class was 1.57 ± 0.62 in the annuloplasty group and 1.45 ± 0.57 in the combination group; there was no signifi cant diff erence in NYHA function class between the fi rst and fi nal follow-ups (P > 0.05).Conclusion iPMD is a valuable index in the risk stratifi cation of the recurrence of post-MAP MR in patients with DCM complicated by FMR. The patients treated with MAP plus PMA had more favourable outcomes and lower recurrence rates than those treated via the traditional route of MAP only." @default.
