Evaluation of Systemic Microcirculatory Vessel Density in the Early Postoperative Period of Heart Valve Surgery: an Observational Study

After cardiac valve surgery, there was an improvement in microvascular parameters concerning capillary vessels and in the total number of microvessels. Moreover, significant positive correlations were found between the use of milrinone and these parameters. The study demonstrated the usefulness of handheld cameras for bedside evaluation of the microcirculation.
