Of 1,237 degenerative cases, 1,234 were repaired; overall operative mortality was 0.3%. The report describes favourable outcomes as subsequent surgeons joined an experienced programme. How to interpret this: Historical institutional results across four surgeons, not 1,410 operations by Chikwe. Most degenerative cases had isolated P2 prolapse; results should not be assumed for every complex valve.

Read alongside Joanna Chikwe’s profile → Barlow durability measured separately The Barlow analysis reported 92% survival free from greater-than-moderate regurgitation at five years, with a wide 95% confidence interval of 80.2%–98.1%.
