Coronary artery anatomy before and after direct revascularization surgery: clinical and cinearteriographic studies in 67 selected patients

Quantitatively assessed coronary collateral circulation and restenosis following percutaneous revascularization

“…After surgical coronary artery bypass grafting, an accelerated progression of native vessel disease has been well documented, both in vessels in which the preoperative diameter stenosis was greater than 50% [26][27][28] , and also in normal segments that lie between a significant stenosis and the bypass graft anasthomosis [29] . This phenomenon has been attributed to increased distal pressure induced by the graft, decreasing transtenotic flow [26,30] .…”

Progression of atherosclerosis after venous coronary artery bypass graft surgery: A 15-year follow-up study

“…However, when comparing the rates of progression of atherosclerosis in vein grafts with all native coronary arteries, no big differences were found [21][22][23]. Moreover, it has been suggested there is no difference in progression in native coronary arteries when comparing progression distal to a graft insertion with progression in nonrevascularized coronary arteries [24][25][26]. It also has been suggested that the recurrence of angina pectoris is mainly caused by progression of disease in the native coronary circulation, although other investigators did find a higher attrition rate of the venous grafts in patients with angina [22,[27][28][29][30].…”

Results of a randomized study of medical and surgical management of angina pectoris

“…In 90% of instances in our study, the procedure was done 10 months or more after operation. The reported experience from other sizable series, as well as the proportion of surgically treated patients who were studied 6 months or longer after surgery, is given in Table 2 [24,[29][30][31][32][33][34]. In a report by Grondin et al [35] from Montreal on 60 consecutive surgical patients who were studied, the overall graft patency rate was 68% at 12 months.…”
