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.

History Of

A case of heart transplantation with concomitant coronary artery bypass graft is reported. The patient was an alternate transplant list candidate with a history of bilateral below-knee amputation and 2 previous myocardial revascularization procedures. The previously used and patent left internal mammary artery graft was successfully removed and retransplanted from the recipient to the donor heart.

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).

Operative Assessment

Background: In coronary artery bypass surgery (CABG) left internal mammary artery (LIMA) is considered gold standard conduit of choice for myocardial revascularization. Graft failure following CABG reduces cardiac mortality and morbidity both in short and long term. Although conventional angiography is gold standard for assessing graft patency but rarely available in same operating room. So intraoperative florescence imaging could be an efficient and reliable method of assessing the patency of graft.Methods: This study was conducted between July 2013 to June 2014 in the Department of Cardiac Surgery of National Institute of Cardiovascular Diseases (NICVD). Thirty six LIMA grafts were assessed by using IFI system .ICG administered through CVP line and imaging acquired during pass of the ICG through field of view graft flow. Quality of anastomosis was intra operatively to validate graft.Results: Mean age of study population was 54±8.38 years. Per operative assessment of LIMA to left anterior descending artery revealed 32 (88.8%) patent anastomosis, narrowing of anastomosis was found in 2 (5.55% ) patients.Conclusion: Intraoperative fluorescence imaging is an effective and inexpensive way to validate patency of LIMA graft.Cardiovasc. j. 2018; 10(2): 145-149
