Bleeding in minimally invasive versus conventional aortic valve replacement.

ABSTRACT:

Background

Observational studies have shown reduced perioperative bleeding in patients undergoing minimally invasive, compared with full sternotomy, aortic valve replacement. Data from randomized trials are conflicting.

Methods

This was a Swedish single center study where adult patients with aortic stenosis, 100 patients were randomly assigned in a 1:1 ratio to undergo either minimally invasive (ministernotomy) or full sternotomy aortic valve replacement. The primary outcome was severe or massive bleeding defined by the Universal Definition of Perioperative Bleeding in adult cardiac surgery (UDPB). Secondary outcomes included blood product transfusions, chest tube output, re-exploration for bleeding, and several other clinically relevant events.
