Key result
Incomplete annuloplasty rings for ischaemic mitral valve repair were associated with more prolonged ventilation (P=0.002) but no significant differences in residual MR, mortality, or survival compared to complete rings.
Why the study?
The choice of ring type for mitral valve repair remains debatable and is usually left to the surgeon's discretion.
Does the use of an incomplete annuloplasty ring compared to a complete ring improve early and mid-term outcomes in patients undergoing repair of ischaemic mitral regurgitation?

Does the use of an incomplete annuloplasty ring compared to a complete ring improve early and mid-term outcomes in patients undergoing repair of ischaemic mitral regurgitation?
The choice between complete and incomplete annuloplasty rings for ischaemic mitral regurgitation repair does not significantly impact early and mid-term clinical or echocardiographic outcomes.
No differences in residual MR or survival support equipoise between ring types; leaves open impact on prolonged ventilation in ischaemic MR repair.
BACKGROUND: The choice of ring type for mitral valve (MV) repair is still debatable and usually is left to the surgeon's discretion. AIM: The aim of this study was to compare the early and mid-term results after repair of ischaemic mitral regurgitation (MR) with complete and incomplete annuloplasty rings. METHODS: Collected data included preoperative assessment (age, sex, comorbidities, clinical status, NYHA grade, and the EURO score); intraoperative details (echocardiography, degree of MR, and cross-clamp time); and results (the length of ICU and hospital stay, duration and need for inotropes, duration of mechanical ventilation, and postoperative adverse events). Follow up after discharge included assessment of dyspnea status, the degree and progression of MR, and left ventricular function and dimensions. RESULTS: The present study included 133 patients: 61 with incomplete rings and 72 with complete rings inserted. There was no significant difference in the rate of postoperative complications between the two groups, apart from a significantly higher percentage of patients with incomplete ring who required prolonged ventilation >24 hours (P = 0.002). There were no significant differences between the two groups, regarding the grade of residual MR (P = 0.464), postoperative dyspnea status (P = 0.723), 30-day mortality rate (P = 0.687), and mean duration of survival (P = 0.276). CONCLUSION: The choice of incomplete or complete annuloplasty ring was not associated with a marked difference in the early and midterm results of ischaemic MV repair.

Soliman et al. (2021) conducted a cohort in Ischaemic mitral regurgitation (n=133). Incomplete annuloplasty ring vs. Complete annuloplasty ring was evaluated on Early and mid-term results including residual MR, 30-day mortality, and survival. Incomplete annuloplasty rings for ischaemic mitral valve repair were associated with more prolonged ventilation (P=0.002) but no significant differences in residual MR, mortality, or survival compared to complete rings.
