A new multipurpose aortic root cannula for open-heart surgery

Abstract

Cold cardioplegic infusion is widely and successfully used today for myocardial protection. Cardioplegic solution is administered using a variety of means and techniques. This paper introduces a newly developed double-lumen cannula that allows the delivery of cardioplegic solution via the aortic root with simultaneous air aspiration, thus preventing coronary artery embolization. The featured double- lumen is useful for the removal of air from the aortic root after the releasing of the aortic cross-clamp. This aortic cannula also features an additional port that provides monitoring of the infusion pressure in the aortic root. This cannula has been used safely, effectively and without complications in 200 cases and we think it is a valid aid in open-heart surgery.
