WHAT IS THE BEST ACCESS FOR ANGIOGRAPHY IN PATIENTS WITH A SINGLE IN-SITU LEFT MAMMARY ARTERY GRAFT

Methods: from a prospective database between Jan 2009 and Oct 2011 of 557 coronary angiography in patients treated with at least one mammary graft, we extracted 341 angiography in patients with one Left Mammary graft (14 operators). Quality of left mammary angiography was assessed by one independent reviewer: 1 or 2 respectively for selective or subselective truly diagnostic angio (graft, anastomosis and distal bed), 3 for non selective good visualization of graft and partial analysis of distal vessels, 4 for graft patency or not diagnosis only. Continuous variables are described as median and interquartile ranges (25th/75th), comparisons are done using non parametric statistics.
