Update on minimally invasive cardiac surgery and enhanced recovery after surgery.

Abstract

Numerous recent trials have examined the potential benefits of treating cardiac surgery patients with a minimally invasive approach. Recently, Enhanced Recovery After Surgery (ERAS) has also been applied to cardiac surgery, and specifically to minimally invasive cardiac surgery (MICS) patients. This review will explore current evidence regarding MICS, as well as the combination of MICS plus ERAS. Multiple contemporary prospective and retrospective trials have published data demonstrating equivalent or better outcomes with reduced length of stay (LOS) for MICS patients compared to patients undergoing full sternotomy. In fact, recent reviews and met-analyses suggest that MICS is associated with reduced atrial fibrillation, wound complications, blood transfusion, LOS, and potentially cost. Additionally, several new trials reporting longer term follow-up on MICS coronary and valve surgery have demonstrated durable results. Emerging literature on the benefits of combining MICS and ERAS perioperative protocols have also reported promising results regarding reduced LOS and faster recovery. Minimally invasive cardiac surgery appears to provide patients with equivalent or better outcomes, faster recovery, and less surgical trauma compared to full sternotomy. The addition of ERAS phase specific perioperative protocols can help maximize the benefits of MICS.
