Description
OBJECTIVE: Ischaemic Mitral Regurgitation (IMR) is a significant source of morbidity and mortality. its optimal treatment has eluded clinicians for decades. The customised ischaemic Mitral Ring (IMR) annuloplasty has emerged as a promising innovative intervention to improve outcomes. we report the early outcomes of our experience with this intervention.
METHODS: Retrospective data analysis of consecutive patients with at least moderate ischaemic mitral regurgitation (vena contracta width 3 to less than 7mm) treated with the IMR annuloplasty in a single centre over a 3year period. All patients had complete concomitant surgical myocardial revascularisation and implantation of customised IMR annuloplasty ring. Outcome measured were survival, freedom from >moderate mitral regurgitation at 1 year and reverse ventricular remodelling using Left ventricular Ejection Fraction (LVEF) and left ventricular internal diastolic Dimension (LVIDD) as surrogate marker. data presented as median interquartile range.
RESULTS: 13 patients were included, Age 74(65-83) years, preoperative LVEF 40(20-55) %, Preop LVIDD 55(45-66) mm, post operative LVEF at 1yr 50(30-60)%, post operative LVIDD at 1yr 45(44-61) mm, Freedom from at least moderate MR at 1 year 12/13(92%), Mortality 2/13(15%), mortality was associated with poor ventricle LVEF < 25% and advance age >75 years
CONCLUSIONS: Use of the customised IMR ring annuloplasty and complete revascularisation is associated with reverse ventricular remodelling and freedom from mitral regurgitation at 1 year. this strategy in suitable patients would lead to improve outcomes. Severely impaired left ventricle with preoperative LVEF < 25% and age >75 years are associated with adverse outcome
