Long-term clinical outcomes of robotic-assisted surgical coronary artery revascularisation
Authors' conclusion
Robotic-assisted CABG and HCR provide good long-term outcomes in patients who are not candidates for conventional CABG.
Study context
- Population
- Patients not candidates for conventional coronary artery bypass grafting (CABG) undergoing robotic-assisted CABG (LITA-LAD via 4 cm left thoracotomy), with HCR (non-LAD stenting within 7 days) where applicable, May 2005–June 2021
- Participants
- 2,280 consecutive patients
- Exposure
- Robotic-assisted CABG across three time periods
- 2005-2010n = 615reference
- 2011-2016n = 904
- 2017-2021n = 761
- Outcome
- Long-term outcomes:
- All-cause death
- MACCE
- Non-fatal stroke
- Repeat revascularisation with stents
- Follow-up
- Mean 4.2 years
