Direct aortic cannulation in minimally invasive mitral-valve operations . The minimally invasive Port-Access ( Heartport , Redwood City , CA ) approach in mitral-valve operations originally required femoral arterial cannulation , which is considered a disadvantage , especially in patients with peripheral vessel disease . In this study 20 patients were prospectively randomized into 2 groups , to undergo either standard femoral ( group A ) or direct aortic cannulation ( group B ) . Pre- and postoperative data as well as markers for myocardial damage were assessed . Postoperatively , patients of group B showed lower levels of damage , indicating that direct aortic cannulation might provide better myocardial protection . Furthermore , the direct aortic cannulation technique may eliminate complications associated with the standard femoral artery cannulation .
