Abstract

Coronary angiography is the most commonly used invasive method for coronary pathology evaluation. The practical applications of this method are both in the diagnostic phase by assessing lesion’s anatomy (such as the lesion location) as well as in the treatment phase of interventional revascularisation. The graft angiography is similar to that used in native vessels, with specific procedures for the appropriate visualisation of the venous or arterial grafts. The mechanisms involved in recurrent post-surgery ischemia are represented by the significant bypass lesions and /or disease progression in the native vessels. The effectiveness of surgical myocardial revascularization decreases in time by the appearance of atherosclerotic lesions at the level of venous grafts. Arterial grafts are more resistant to atherosclerosis but their patency is affected by the competitive flow. The degree of preoperative native vessels stenosis is used as surrogate for competitive flow, graft patency being frequently correlated with significant stenoses.
