The long-term effect of recanalisation of a CTO on LV function and volumes is currently unknown.
To investigate early and late effects of percutaneous revascularization for chronic total coronary occlusion (CTO) on left ventricular (LV) function and volumes.
MRI was performed in 21 patients before, at 5 months, and at 3 years after recanalisation of CTO. Global LV function and volumes and segmental wall thickening (SWT) were quantified on cine-images. Two viability indexes were used; the transmural extent of infarction (TEI) on delayed contrast enhancement images and end-diastolic wall thickness at baseline (EDWT).
A positive effect on LV remodelling and EF is observed up to three years after recanalisation. Both early and late improvement of regional LV function is observed in the perfusion territory of CTO and is related to the transmural extent of infarction on pre-treatment MRI.
