Overview

Patients undergoing minimally invasive mitral valve reconstruction via small thoracotomy are randomized into two groups.

The intervention group receives serratus anterior plane block after minimally invasive mitral-valve reconstruction, following 48h infusion with ropivacaine 2% continually.

The control group receives a placebo pump without infusion. Primary endpoints are perceived pain using a numeric pain rating scale and opioid consumption during the hospital stay.
