Endoscopic harvesting device type and outcomes in patients undergoing coronary artery bypass surgery.

ABSTRACT: To evaluate angiographic and clinical outcomes associated with open and closed dissection tunnel endoscopic vein harvesting (EVH) devices.A previous PREVENT-IV (PRoject of Ex-vivo Vein graft ENgineering via Transfection IV) analysis reported that EVH for coronary artery bypass graft surgery was associated with worse outcomes than with traditional vein harvesting; however, outcomes by EVH device type were not available.Using data from the PREVENT-IV trial, we compared 1549 patients from 75 surgical sites who underwent EVH with open (n = 390) or closed (n = 1159) harvest tunnel devices. Outcomes included the incidence of vein graft failure at 12 to 18 months and a composite of death, myocardial infarction, and revascularization through 5 years.Among patients undergoing open and closed tunnel EVH, no difference in the per-patient incidence of vein graft failure (43.8% vs 47.1%; adjusted odds ratio, 0.91; 95% confidence interval, 0.53-1.55; P = 0.724) or per-graft incidence of vein graft failure (25.5% vs 25.9%; adjusted odds ratio, 0.96; 95% confidence interval, 0.59-1.55; P = 0.847) was observed. At 5 years, no difference was observed in the primary composite clinical outcome between patients who underwent open and closed system EVH (21.5% vs 23.9%; adjusted hazard ratio, 0.85; 95% confidence interval, 0.66-1.10; P = 0.221).No differences in angiographic or clinical outcomes were observed among patients who underwent open versus closed tunnel endoscopic harvesting for coronary bypass surgery. These findings suggest that the risks associated with EVH that were reported in a previous PREVENT-IV analysis are not related to a specific EVH device.

Project description:Background-Coronary endarterectomy (CEA) has been introduced to allow revascularization in end-stage coronary artery disease (CAD). After CEA, the injured remnants of the vessel's media could result in fast neo intimal tissue ingrowth, which require an anti-proliferation agent (antiplatelet therapy (APT). We aimed to review outcomes of patients undergoing CEA within bypass surgery who received either single-APT (SAPT) or dual-APT (DAPT). Methods-We retrospectively evaluated 353 consecutive patients undergoing CEA within isolated coronary artery bypass grafting (CABG) in the period 01/2000-07/2019. After surgery, patients received either SAPT (n = 153), or DAPT (n = 200) for six months then lifelong SAPT. Endpoints included early, late survival, and freedom from major-adverse-cardiac and cerebrovascular events (MACCE), which were defined as incidence of stroke, myocardial infarction, need for coronary intervention (PCI or CABG) or death for any cause. Results-Patients' mean age was 67 ± 9.3 years; they were predominantly male 88.1%. Both DAPT- and SAPT-groups had the same extent of CAD (mean SYNTAX-Score-II: 34.1 ± 11.6 vs. 34.4 ± 17.2, p = 0.91). Postoperatively, no difference between DAPT- and SAPT-groups was reported in the incidence of low-cardiac-output syndrome (5% vs. 9.8%, p = 0.16), revision for bleeding (5% vs. 6.5% p = 0.64), 30-day mortality (4.5% vs. 5.2%, p = 0.8) or MACCE (7.5% vs. 11.8%, p = 0.19). Imaging follow-up reported significantly higher CEA and total grafts patency (90% vs. 81.5% and 95% vs. 81%, p = 0.017) in DAPT patients. Late outcomes within 97.4 ± 67.4 months show lower incidence of overall mortality (19 vs. 51%, p < 0.001) and MACCE (24.5 vs. 58.2%, p < 0.001) in the DAPT patients when compared with SAPT patients. Conclusions-Coronary endarterectomy allows revascularization in end-stage CAD when the myocardium is still viable. The use of dual APT after CEA for at least six months seems to improve mid-to-long-term patency rates and survival, and reduced the incidence of major adverse cardiac and cerebrovascular events.
