Background: The evolution toward "more physiologic" cardiac surgery targets reduction of both surgical trauma and the systemic sequelae of cardiopulmonary bypass (CPB). Minimal Invasive Extracorporeal Circulation (MiECC) incorporates biocompatible closed circuits to attenuate the inflammatory cascade, while Minimally Invasive Cardiac Surgery (MICS) limits mechanical access. Their integration represents a paradigm shift aimed at synergistically improving patient outcomes in adult cardiac surgery.

Methods: This narrative review synthesizes current evidence from clinical trials, observational studies, and meta-analyses. Literature was evaluated to examine the technical synergy, pathophysiological rationale, and reported clinical outcomes of combining MiECC with MICS, primarily in coronary artery bypass grafting (CABG) and isolated valve procedures.

Results: Evidence confirms that MiECC alone, versus conventional CPB, significantly reduces inflammatory markers (e.g., IL-6, TNF-α), transfusion rates (approximately 20-30%), acute kidney injury (relative risk reduction ~25%), and ICU length of stay (by ~1.5 days). Preliminary data from combined MiECC-MICS applications in CABG and mitral valve surgery suggest additive benefits, including further reductions in transfusion needs, postoperative atrial fibrillation, and time to extubation, though large-scale comparative data remain limited.

Conclusions: The integration of MiECC and MICS forms a compelling multidisciplinary strategy toward physiologically optimized cardiac surgery. Available data support enhanced recovery profiles, justifying this combined approach. Prospective, procedure-specific comparative studies are now mandated to definitively quantify synergistic effects on major clinical endpoints, neurocognitive outcomes, and cost-effectiveness.
