Summary： To investigate the clinical use of π graft in total arterial revascularization and its outcomes, a retrospective analysis of 23 patients out of 1000 patients undergoing total arterial coronary bypass surgery with a π graft between September 1994 and December 2004 was performed. In the selected patients for the management of triple vessel disease with middle diagonal/intermediate ramus disease such that a skip with the left internal mammary artery （LIMA） or radial artery （RA）, the main stem of π graft, to the left anterior descending coronary artery （LAD） will not work and the right internal mammary artery （RIMA） or right gastroepiploic artery （RGEA） cannot pick up the diagonal/intermediate ramus, hence the LAD and diagonal/intermediate ramus were grafted with a mini Y graft using the distal segment of LIMA, RIMA, RA or RGEA, together with the bilateral internal mammary artery （BIMA） or LIMA-RA T graft to compose π graft. Twenty-three patients （18 males, 5 females） underwent the π graft procedure. There were no deaths or episodes of myocardial infarction, stroke, and deep sternal wound infection. One patient required reopening for controlling bleeding. Until the end of 2004, during a mean follow-up of 81.0±28.4 months, no angina needing re intervention or operative therapy or coronary related death occurred. In conclusion, in patients with specific coronary artery anatomy/stenosis, the BIMA （sometimes LIMA with RA or RGEA） π graft can be successfully performed for total arterial revascularization with good midterm outcomes.

Background total arterial revascularization （TAR） was widely utilized in coronary artery bypass grafting （CABG） as a result of its better long-term effect compared with vein grafts. Of the arterial conduits, radial artery （RA） gained popularity for its easy availability and reported long-term patency. Thus, the objective of this study was to investigate the effect of RA in TAR in CABG. Methods From January 2000 to December 2006, 85 patients （56 male and 29 female） at a mean age of 57.0 ± 5.2 years, underwent TAR in CABG. RA and left internal mammary artery （LIMA） with composite Y or T and sequential grafting techniques were used. Post-operative complications were recorded and follow-up was performed. Results Eighty-five LIMA and 149 RA grafts including 21 single and 64 bilateral RA were collected. A total of 87 distal anastomoses were done with the LIMA and another 152 were done with the RA, with the mean number of distal anastomosis per patient of 2.81 ± 0.47. The proximal RA ends were anastomsed directly to the aorta in 140 grafts with Y or T graft off in situ LIMA in 9, Y or T graft off RA in 9. The distal end was anastomsed to right coronary artery system in 92 to obtuse margina in 46, to diagonal in 19 and to ramous intermedius in 5. Nine sequential anastomoses were performed with RA. Nine composite Y or T grafts were constructed with RA and LIMA while another 9 were constructed with RA and RA. One （1.2%） patient died, 3 patients （3.5%） experienced acute renal failure and 2 （2.4%） developed stroke. All patients were still alive and no patient had evidences of newly occurred myocardial infarction or angina after a mean follow-up of 36.5 ＋ 4.1 months （6-67 months）. Postoperatively at 6 month, mean left ventricular ejective fraction was increased to 0.49 ±0.09, compared with that of 0.43 ± 0.11 preoperatively （P=-0.027）. Postoperative mean New York Heart Association class was 2.5±0.5, compared with that of 3.0±0.4 preoperatively （P=-0.003）. Conclusions TAR w

Background： arterial grafts had better mid-term and long-term patency than saphenous vein grafts in coronary artery bypass grafting （CABG）. We summarized our experience with total arterial off-pump coronary artery bypass grafting （OPCAB） and assessed the early clinical results, surgical complications, and follow-up. Methods： From January 2007 to May 2017,508 coronary artery disease patients undergoing total arterial OPCAB were enrolled. Clinical features, approaches, outcomes of surgical treatments, and follow-up data of these patients were studied retrospectively. A total of 122 patients underwent single left internal mammary artery （IMA）-left anterior descending artery grafts, whereas the other 386 patients underwent multiple vessel grafts. Results： The average distal anastomosis was 2.34 ± 0.97 （range： 1-4）. All the patients were discharged from hospital except one died. A total of 457 （90.32%） patients were followed up. In the 4-, 7-, and 10-year follow-up groups, the rate of death from any cause was 1.19%, 6.47%, and 10.67%; rate of cardiac death was 0.60%, 2.88%, and 3.33%; rate of repeat revascularization was 0.00%, 3.60%. and 8.67%; rate ofischemic symptoms was 1.79%, 7.91%, and 11.33%; and incidence of stroke was 2.38%, 4.32%, and 6.67%, respectively. Poor medication adherence was observed in 9.38% of the follow-up population. Conclusions： total arterial OPCAB with bilateral IMA, radial artery, and right gastroepiploic artery grafting yielded satisfactory early and midterm outcomes in this patient group, without a significant increase in early mortality or morbidity. Moreover, the long-term outcomes are also positive.

total arterial Revascularisation in Left Ventricular Dysfunction

Journal of Huazhong University of Science and Technology(Medical Sciences) 2006年第1期26卷 82-85页

作者：邓勇志孙宗全 Hugh S PATERSON Department of Cardiovascular Surgery Union Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan 430022 China Department of Cardiothoracic Surgery The Second Affiliated Hospital Shanxi Medical University Taiyuan 030001 China Department of Cardiothoracic Surgery Westmead Hospital Sydney University NSW 2145 Australia

The feasibility and safety of total arterial coronary revascularization with 2 arterial conduits in patients with impaired left ventricular function was evaluated. Data were prospectively collected on all patients with multiple vessel disease and moderately or severely impaired left ventricular function, who underwent coronary surgery with the intention of total arterial revascularization with 2 conduits between March 1995 and August 2002. One hundred and seventy-nine patients were included in the study. Acute coronary insufficiency was present in 3 patients and 43 had unstable angina. Severe left ventricular impairment was present in 29 patients. There were 17 redo operations including 3 redo-redo procedures. Eighty-two percent of patients had a Y graft configuration from the left internal mammary artery （right internal mammary artery 40. 8 %, radial artery 33. 5 %, other 7.8 % ）. The perioperative mortality was 2. 2 %, myocardial infarction 1.7 % and stroke 0. 6 %. total arterial revascularization in patients with ischaemic left ventricular dysfunction can be safely performed with 2 arterial conduits. The radial artery provides conduit length greater than the right internal mammary artery and allows full revascularization despite left ventricular dilatation.
