OBJECTIVE: To evaluate the impact on cardiac magnetic resonance imaging (CMRI) with @entity859 stress and delayed enhancement for indication and follow up after interventional recanalisation of chronic total coronary occlusions (CTOs). MATERIAL AND METHODS: Twenty consecutive @entity1 (15 males; 5 females; mean age 65 years) with CTO verified by cardiac catheterisation referred to CMRI. Sixteen of them got CMRI before and after coronary recanalisation. @entity854 ( @entity854 ), first pass perfusion with @entity859 and viability were assessed using a 1.5 T MR scanner (Sonata; Siemens). CMRI results were compared with clinical classifications, the results of cardiac catheterisation and follow up angiography. RESULTS: Sixteen @entity1 had a successful recanalisation, 15 of the occluded coronary artery and one of collateral donor artery stenosis. After recanalisation all stress-induced progressive or new @entity854 ( @entity854 ) of the corresponding segments and in the collateral donor territory (5 @entity1 ) and all @entity859 induced @entity154 ( @entity154 ) or delay (12 @entity1 ) were regredient. 13/16 @entity1 showed no transmural and one @entity1 transmural delayed enhancement (DE) indicating @entity296 . In 10/16 @entity1 CSS grading of angina improved after recanalisation. CONCLUSION: After successful recanalisation of CTOs, @entity1 with preinterventional stress-induced PDs and @entity854 in viable myocardium did not display any signs of stress-induced @entity63 postinterventionally. A comprehensive CMRI approach, including assessment of rest and stress @entity854 , first pass perfusion and myocardial viability represents an important tool for the pre-interventional decision to recanalise CTOs and follow up.
