Transcatheter treatment of angina after coronary surgery due to concomitant internal mammary steal and right coronary artery stenosis: a need for staging.
Unligated side branches of the internal mammary artery used as a conduit in bypass surgery can be responsible for a flow steal phenomenon, causing recurrent angina. In this report we describe such a case, which was treated with a transcatheter embolization technique using coils as an alternative to surgery. However, heparin administration for simultaneous balloon dilatation of another lesion delayed successful embolization. Whenever balloon dilatation and embolization have to be performed on the same patient, both procedures should be staged to avoid heparin administration during and after the embolization procedure.
