It involved the left main coronary artery in four and the right coronary artery originating from the left anterior descending coronary artery in two patients. Conduit types were homograft (<jats:italic>n<\/jats:italic>\u2009=\u20093), bioprosthesis (<jats:italic>n<\/jats:italic>\u2009=\u20092), and a pericardial patch (<jats:italic>n<\/jats:italic>\u2009=\u20091). Median diameter was 23 (17\u201324) mm at surgical implantation. CC was diagnosed through a selective coronary angiogram during balloon dilation of the conduit in the first three patients and through an aortic root angiogram for the three next cases because we recognized that proximal compression could be masked during coronary artery cannulation. It was suspected on pre\u2010procedure imaging (magnetic resonance imaging and\/or computed tomography) in three cases. Patients with abnormal coronary anatomy tend to be at increased risk of CC (<jats:italic>P<\/jats:italic>\u2009=\u20090.0504). One institution had a higher incidence of CC (<jats:italic>P<\/jats:italic>\u2009=\u20090.04). CC resolved after balloon deflation. No patient underwent conduit stenting.
