Five-year total-arterial MICS outcomes

Davierwala coauthored a 186-patient elective series from 2015–2021. Bilateral internal thoracic arteries were used in 88%; there was one hospital death and two conversions to sternotomy. Estimated five-year survival was 93.3%.

How to interpret this: Selected single-centre cohort associated with the Leipzig programme. It is historical experience, not a current Toronto result or a head-to-head proof that every patient benefits from this strategy.
