In 14 of these patients, the intramural site of origin (SOO) was identified with multipolar catheters. The intramural SOO could not be accessed with mapping catheters in the other 15 patients while mapping the coronary venous system. The CTA identified sizable proximal septal veins in all patients in whom the SOO could be accessed with mapping catheters. In the patients in whom the intramural SOO was not identified, the proximal septal veins were often either small (&lt;2\u2009mm at\u00a0the branching site) or non\u2010existent (<jats:italic>n<\/jats:italic>\u2009=\u20099, <jats:italic>p<\/jats:italic>\u2009=\u2009.001).
