Key result
Restrictive annuloplasty combined with CABG for chronic ischaemic mitral regurgitation showed no 10-year survival benefit compared to CABG alone (approximately 50% for both).
Absolute Event Rate: 50% vs 50%
Restrictive annuloplasty for chronic ischemic mitral regurgitation has high recurrence rates and no long-term survival benefit over CABG alone, highlighting the need for new mechanism-based surgical approaches.
No takes yet. Share an insight, caveat, or question.
No survival benefit supports avoiding routine restrictive annuloplasty; leaves open mechanism-based surgical strategies for chronic ischaemic mitral regurgitation.
Bouma et al. (2009) conducted a review in Chronic ischaemic mitral regurgitation. Restrictive annuloplasty combined with CABG vs. CABG alone was evaluated on 10-year survival rate. Restrictive annuloplasty combined with CABG for chronic ischaemic mitral regurgitation showed no 10-year survival benefit compared to CABG alone (approximately 50% for both).
