Coronary Steal

A case of coronary steal syndrome caused by a large unligated branch of the left internal mammary artery in a patient who had undergone myocardial revascularization is described. The presence of recurrent angina, a positive exercise stress test, and repeat angiography showing a lateral branch of the mammary artery led to a diagnosis of the coronary steal phenomenon. Surgical ligation of the branch was performed and the patient became symptom-free with a negative exercise stress test.

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.
