“…25) Several studies have reported that stent implantation is an option in cases of refractory CAS with a focal lesion; 30,31) however, stenting in patients with CAS is associated with complications such as stent-edge spasm and stent crush phenomenon and therefore should be carefully considered. 32,33) If CAS is intraoperatively identified, it may be treated by drug infusion directly through the bypass graft. 25) In hemodynamically unstable patients, the use of an IABP can increase the coronary flow and support the struggling left ventricle.…”

SummaryCoronary artery spasm after coronary artery bypass surgery may result in life-threatening arrhythmias, circulatory collapse, or death. We report two cases of coronary artery spasm after coronary artery bypass surgery, one of which developed ventricular fibrillation requiring extracorporeal membrane oxygenation support. Both patients were discharged in good condition and are currently followed as outpatients. Unexpected sudden hemodynamic compromise could be due to coronary vasospasm, and this should be considered as one of the possible differential diagnoses. We were able to prevent the lethal consequences seen with coronary artery spasm by early diagnosis and management. (Int Heart J 2014; 55: 451-454)

“…[8][9][10][11][12][13][14] However, stenting in patients with coronary spasm has various problems, such as new onset stent-edge spasm and stent crush phenomenon. [15][16][17] Therefore, when performing stenting for refractory coronary spasm, complications associated with this strategy need to be considered and stenting should be considered as the last choice for the treatment of coronary spasm.…”

Coronary Artery Multistenting in the Treatment of Life-Threatening Refractory Coronary Spasm After Coronary Artery Bypass Grafting

SUMMARYA 74-year-old man had undergone on-pump coronary artery bypass grafting (CABG) for effort-induced angina pectoris. Soon after CABG using the left internal thoracic artery for the left anterior descending artery and saphenous vein for the left circumflex artery, ST elevation was found in the inferior leads and complete atrioventricular block, ventricular tachycardia, and circulatory collapse occurred. Emergent coronary angiography revealed diffuse severe spasm of the right coronary artery (RCA). Despite the intravenous and intracoronary administration of massive doses of vasodilators and intra-aortic balloon pumping, the coronary spasm did not resolve. Five stents were deployed from the distal to the proximal portion of the RCA. After multistenting, coronary flow was dramatically improved and the ST elevations in the inferior leads were also improved. Coronary artery spasm after CABG is relatively rare, but when it occurs, it can be fatal. Multistenting is a useful treatment for life-threatening refractory coronary spasm after CABG. (Int Heart J 2007; 48: 379-385) Key words: Coronary artery spasm, Coronary artery bypass grafting, Multistenting CORONARY artery spasm after coronary artery bypass grafting (CABG) is relatively rare, but when it occurs, it can be fatal. In this situation, coronary spasm is sometimes resistant to vasodilating drugs, which are usually effective for coronary spasm, and malignant arrhythmias or circulatory collapse can frequently occur. [1][2][3][4][5] We present a patient with life-threatening refractory coronary spasm after CABG in whom massive administration of vasodilating drugs, such as isosorbide dinitrate (ISDN), nitroglycerin, nicorandil, and diltiazem, and intra-aortic balloon pumping (IABP) were not effective in resolving the spasm. For this patient, we performed multistenting for the spasm sites and obtained good results.From the

“…LSS can be caused by interaction with the stent and guide catheter, balloon, another stent or ultrasound catheter [4]. On the other hand, few authors have reported stent collapse (deformity in radial direction and narrowing in area inside stent) occurring immediately after stenting [5,6]. Immediate stent collapse can be caused by vascular spasm [5] and elastic recoil of the vessel [6].…”

“…On the other hand, few authors have reported stent collapse (deformity in radial direction and narrowing in area inside stent) occurring immediately after stenting [5,6]. Immediate stent collapse can be caused by vascular spasm [5] and elastic recoil of the vessel [6]. We herein report a rare complicated case, that we believe is the first report, with remarkable CoCr everolimuseluting stent (EES) collapse caused by the excess negative pressure generated by the distal occlusion and aspiration procedure under the completely wedged guide catheter into the ostium of the target vessel.…”
