Full Metal Jacket

Objective: Modern coronary interventional practice can result in coronary vessels that are totally stented. The term “full metal jacket” has been coined to refer to vessels that have an overlapping stent in series along the whole length of the vessel. This poses a serious challenge to surgical revascularization, particularly when a left internal thoracic artery (LITA) to the left anterior descending (LAD) needs to be undertaken. We evaluated the early and midterm results of on-pump coronary artery bypass grafting (CABG) following “stent endarterectomy” for the LAD with LITA to LAD grafting. Methods: During October 2017 to September 2020, 21 patients presented with multi-vessel disease and a totally occluded LAD with a stent full metal jacket. No distal target for LITA grafting was available, despite a viable myocardial territory. The LAD was endarterectomised, removing the column of totally occluded stents with the medial wall of the vessel, leaving the proximal stent in place to avoid competitive flow. Long length anastomosis was then undertaken with the LITA graft. Postoperatively, patients were followed up clinically and by coronary computed tomography (CT) angiography at 6- and 18-month intervals. All patients were discharged on a combination of aspirin and warfarin for three months and then aspirin and clopidogrel for the rest of the first year and then aspirin alone for life. Results: Patients had a mean age of 58.07 ± 2.06 yr. Sixteen (76.2%) were males, 13 (61.9%) patients were diabetics, 18 (85.7%) were hypertensive, 15 (71.4%) were dyslipidemic, six (28.6%) were obese, 11 (52.4%) were smokers, and five (23.8%) had positive family history of ischemic heart disease (IHD). The number of grafts per patient ranged 3-5, with a mean cross-clamp time of 64.71± 8.84 min. There were no postoperative deaths nor MI clinically, by electrocardiogram (ECG) criteria nor by troponin or CK-MB. In-hospital complications included one (4.8%) patient who required re-exploration for bleeding, one (4.8%) developed a superficial wound, and three (14.3%) developed atrial fibrillation (AF), during their hospital stay. Mean hospital stay was 7.71±1.73 days. All patients completed the 6-month follow up showing patent LITA to LAD with coronary CT angiography. One patient was lost to follow up after six months; five patients are awaiting their 18-month CT angiography, while 15 (71.4%) patients have completed their 18-month CT angiography, and all have a patent LITA to LAD. Conclusions: Stent endarterectomy for a totally occluded LAD with a full metal jacket and viable myocardial territory is a safe procedure with good early and midterm results. This technique should be considered in these difficult cases presenting for revascularisation when no other option is available.

Introduction Multivessel coronary artery bypass graft (CABG) with bilateral internal thoracic arteries (BITA) has only been uncommon and technically demanding. We describe our experience with BITA only CABGs requiring ≥ 4 anastomoses. Material and Methods The department's database was queried for patients undergoing isolated CABG with ≥ 4 anastomoses. The surgical technique included systematically a right internal thoracic artery (ITA) of left ITA Y graft. The multivariate model included variables with a p < 0.3 at univariate analysis. Results Between January 2006 and December 2009, 251 consecutive patients (71 ± 10 years) (on-pump: 130, off-pump: 121) had CABG with ≥ 4 anastomoses, representing 21% of total isolated CABGs for the same period; all patients received a totally arterial BITA only revascularization. Follow-up was 4.9 ± 1.6 years. Overall and cardiac cumulative survivals were 78 and 92%, respectively, at 5 years. The occurrence of any major postoperative complication was associated with overall and cardiac mortality (odds ratio [OR]: 3.6, 95% confidence interval [CI]: 1.3–9.9 and OR: 5.4, 95% CI: 1.3–21.9, respectively). Major sternal wound complication requiring surgical revision was not associated with impaired glucose control (n = 9; diabetics: 6/82, 7.3%; nondiabetics: 3/169, 1.8%, p = 0.06). Preoperative kidney failure was associated with incomplete revascularization (OR: 6.2; 95% CI: 1.2–33.5), that was unfailingly due to ungraftable right coronary artery targets. Discussion BITA only revascularization was a valuable and safe procedure, with favorable results in terms of morbidity and mortality at a 5 years' follow-up.

Vein Harvesting

Background: Utilisation of the Endoscopic Vein Harvesting (EVH) technique has been increasing for coronary artery bypass grafting (CABG) for the last two decades. Some surgeons remain concerned about the long-term patency of the long saphenous vein harvested endoscopically compared to traditional Open Vein Harvesting (OVH). The aim of this study was to perform a retrospective analysis of the outcomes between EVH and OVH from three UK centres with 10 years follow-up. Methods: 27,024 patients underwent CABG with long saphenous vein harvested by EVH (n=13,794) or OVH (n=13,230) in three UK centres between 2007 and 2019. Propensity modelling was used to calculate the Inverse Probability of Treatment Weights (IPTW). The primary endpoint was mortality from all causes and secondary endpoints were length of hospital stay, postoperative complications, and incidence of repeat coronary re-vascularisation for symptomatic patients. IPTW was used to balance the two intervention groups for baseline and preoperative co-morbidities. Results: Median follow-up time was 4.54 years for EVH and 6.00 years for OVH. Death from any cause occurred in 13.8% of the EVH group versus 20.8% in the OVH group over the follow-up period. The hazard ratio of death (EVH to OVH) was 0.823 (95% CI: 0.767, 0.884). Length of hospital stay was similar between the groups (p=0.86). Post-operative pulmonary complications were more common in EVH vs OVH (14.7% vs. 12.8%, p<0.001), but repeat coronary re-vascularisation was similar between the groups. Conclusion: This large retrospective multicentre analysis indicates that EVH has a lower risk of mortality compared with OVH during the follow-up period of the study. The observed benefits of EVH may outweigh the risks but should be considered on a case-by-case basis. We hope this review gives confidence to other cardiac centres that offering an EVH approach to conduit harvesting does not affect long term patient outcomes.

<p><b>Objectives:</b> Despite increasing recognition that off-pump coronary artery bypass surgery and sequential grafting strategy individually are associated with improved outcomes, concerns persist regarding the safety and efficacy of combining these 2 techniques. We compared in-hospital and midterm outcomes for off-pump multivessel sequential and conventional coronary artery bypass grafting.</p><p><b>Methods:</b> From September 1998 to September 2008, 689 consecutive patients received off-pump multivessel sequential coronary artery bypass grafting performed by a single surgeon. These patients were propensity matched to 689 patients who underwent off-pump coronary artery bypass grafting without sequential anastomoses. A retrospective analysis of prospectively collected perioperative data was performed. In addition, medical notes and charts of all the study patients were reviewed. The mean duration of follow-up was 5.1 � 2.0 years.</p><p><b>Results:</b> The major in-hospital clinical outcomes in the sequential and control groups were found to be similar. After adjusting for clinical covariates, sequential grafting was not an independent predictor of in-hospital adverse events (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.86-1.50; <i>P</i> = .31), medium-term mortality (hazard ratio [HR], 1.26; 95% CI, 1.06-1.32; <i>P</i> = .92), and readmission to hospital (HR, 1.12; 95% CI, 0.96-1.20; <i>P</i> = .80). Sequential grafting was an independent predictor of receiving more than 3 distal anastomoses (OR, 7.46; 95% CI, 4.27-11.45; <i>P</i> < .0001). Risk-adjusted survival was 89% for sequential grafting patients and 88% for conventional grafting patients (<i>P</i> = .96) during the medium-term follow-up.</p><p><b>Conclusion:</b> Our analysis confirms the short- and midterm safety and efficacy of off-pump sequential coronary artery bypass grafting.</p>
