Chirurgische koronare Mehrgefäßrevaskularisation: minimalinvasiv vs. konventionelle Sternotomie
摘要
The aim of this meta-analysis was to systematically evaluate the early and mid-term outcomes of minimally invasive multivessel coronary artery bypass grafting (MICS-CABG) compared with conventional bypass surgery with medial sternotomy CABG (ST-CABG). Only propensity score-matched studies including true multivessel revascularization (≥ 2 distal anastomoses) were included. In total, 6 studies comprising 1806 patients (903 MICS-CABG vs. 903 ST-CABG) were analyzed.
Random effects meta-analysis demonstrated no significant differences in in-hospital mortality between the two approaches. Likewise, no significant differences were observed in mid-term clinical endpoints, including 5‑year overall survival and freedom from major adverse cardiac and cerebrovascular events (MACCE).
Importantly, a consistent positive trend favoring MICS-CABG was observed with respect to perioperative complications and length of hospital stay. In particular, transfusion rates and overall in-hospital stay were numerically lower in the minimally invasive group, suggesting a potentially reduced perioperative burden and enhanced postoperative recovery.
These findings indicate comparable early and mid-term safety of both MICS-CABG and ST-CABG in selected patients, with potential advantages of the minimally invasive approach in terms of postoperative recovery. Ongoing prospective randomized trials are expected to further validate and confirm these results.
