Coronary Steal

The left internal mammary artery (LIMA) is a widely used conduit during coronary artery bypass graft (CABG) surgery because of its excellent long-term patency. Although large LIMA side branches are typically ligated during the surgery, the occurrence of a coronary steal phenomenon related to these side branches following surgery remains controversial. Advocates for occlusion of LIMA side branches in the setting of left anterior descending artery (LAD) ischemia indicate that anginal symptoms often improve and that objective measures of LAD ischemia frequently resolve. We present a patient with ischemia in the LAD distribution secondary to coronary steal from a large LIMA side branch that was successfully treated using the Embolization Coil-IMWCE-3-PDA5 (Cook Medical, Bjaeverskov, Denmark).

Coronary Steal

Unligated side branches of the left internal mammary artery (LIMA) have been described in the literature as a cause of coronary steal resulting in angina. Despite a number of studies reporting successful side branch embolization to relieve symptoms, this phenomenon remains controversial. Hemodynamic evidence of coronary steal using angiographic and intravascular Doppler techniques has been supported by some and rejected by others. In this case study using an intracoronary Doppler wire with adenosine, we demonstrate that a trial occlusion of the LIMA thoracic side branch with selective balloon inflation can confirm physiologic significant steal and whether coil embolization of the side branch is indicated.

Internal Mammary

Coronary artery disease (CAD) has become a common diagnosis. Managing the symptoms of CAD continues to be an ongoing dilemma requiring optimal medication management or potential revascularization with either percutaneous coronary interventions or coronary artery bypass grafting (CABG). We present a case of debilitating refractory angina in a patient with severe CAD after optimal medical therapy and CABG secondary to coronary steal phenomenon via the left internal mammary artery conduit supplying a large unligated side branch to the internal chest wall. While current data are inconclusive on this phenomenon, our patient had complete resolution of angina following coil embolization of unligated side branch of the internal mammary artery.
