Background Coronary endarterectomy aims to improve completeness of revascularization in patients with occluded coronary vessels. The benefits of coronary endarterectomy remain uncertain. The aim of this study was to evaluate short-term surgical outcomes and factors affecting graft patency post-coronary endarterectomy. Methods Between 2009 and 2019, 81 consecutive patients who had coronary endarterectomy done were evaluated for their perioperative and early results. A total of 36 patients with follow-up coronary studies were included in patency analysis. Mortality rates, major adverse cardiac and cerebrovascular events, and graft patency were outcomes of interest. Survival and risk factor analysis were performed with Kaplan–Meier and logistic regression analysis. Results The average age of the cohort was 61.9 ± 9.29 years. Complete revascularization rate was 95.4% post-coronary endarterectomy. The 30-day and 1-year mortality was 2.5 and 6.2%, respectively. One-year major adverse cardiac and cerebrovascular events rate was 11.1%. Periprocedural myocardial infarction rate was 7.4%. Three patients required repeat revascularization within a mean follow-up duration of 49.6 ± 36.5 months. Overall graft patency was 89.2% at 20.2 months and graft patency post-coronary endarterectomy was 85.4%. Arterial grafts showed 100% patency. Vein grafts to endarterectomized obtuse marginal branch had patency rates of 33.3%. Multiple endarterectomies were associated with worse one-year major adverse cardiac and cerebrovascular events (OR: 28.6 ± 1.16; P = 0.003). Conclusions Coronary endarterectomy facilitates completeness of revascularization and does not increase early mortality. Graft patency post-coronary endarterectomy on obtuse marginal artery was suboptimal. Judicious use of coronary endarterectomy should be practiced to balance the need of completeness of revascularization against the risk of myocardial infarction.

Abstract Background Multiple spontaneous coronary artery dissection (SCAD) is a rare condition which may lead to serious consequences such as sudden cardiac death, acute myocardial infarction (AMI), and acute heart failure. Case summary In this paper, we report the case of a 57-year-old woman with acute myelocytic leukaemia who was undergoing her second phase of chemotherapy. After the first induction cycle of intravenous infusion of daunorubicin, the patient experienced chest pain, shortness of breath, and low blood pressure. The electrocardiograms revealed significant ST-elevation in the D1, aVL, and V2–V6 leads, which indicated AMI. Coronary catheterization showed spontaneous coronary dissection in the mid-left descending coronary artery and first obtuse marginal artery of the circumflex. The patient died immediately. Discussion This is the first reported case of multiple SCAD associated with intravenous (IV) daunorubicin infusion. We also reviewed the literature and proposed the mechanism of this complication.

An 83-year-old man, who underwent coronary artery bypass operation of left internal mammary artery (LIMA) to left anterior descending (LAD) artery, with sequential saphenous vein to the first and second obtuse marginal (OM) branches of circumflex artery 5 years ago and coronary artery stent implantation to right coronary artery 2 months ago, was admitted to the hospital with syncope and chest pain. Aortosaphenous graft selective angiography revealed that first sequential side to side ligation was inadvertently anastomosed to left posterolateral coronary vein with resultant flow into the coronary sinus and distal end to side sequential anastomosis to OM 2 coronary artery which was filling very weakly. In order to close this iatrogenic coronary arteriovenous fistula and to supply saphenous vein flow to OM artery, we decided to implant a graft covered stent into the saphenous vein at the same session.

A fit 57-year-old man presented with exertional chest pain to the emergency department and was found to have anterolateral T wave inversion on ECG and blood troponin of 1290. Coronary angiography showed a severe proximal to mid-course lesion in mid left anterior descending (LAD) artery, severe ostial disease in obtuse marginal 1 (OM1) and large coronary artery fistula between proximal LAD and main pulmonary artery (PA). Subsequent cardiac CT multiple gated acquisition scan showed a coronary artery to main PA fistula, fed by small branches of the LAD and right coronary artery (RCA). Cardiac magnetic resonance (CMR) showed preserved left ventricle systolic function, ejection fraction 62% and small left to right shunt. Following multidisciplinary team (MDT) discussion, the patient was offered coronary artery bypass grafting (CABG) and fistula ligation as first option, but percutaneous intervention (PCI) to the LAD would also be feasible. After lengthy discussions the patient declined CABG and opted for PCI and stent insertion.
