Right coronary artery dissection during intraoperative ostium cannulation. Presentation of successful treatment

Right coronary artery dissection related to medical procedures is a very rare life-threatening complication caused by a combination of vessel occlusion and myocardial ischaemia. This paper presents a case of dissection which occurred during a Ross cardiac surgery procedure. The complication was observed after proximal right coronary constriction on the cannula used to administer cardioplegia. The damaged part of the internal membrane was resected during the operation. We present a five-year follow-up of this patient.
