Fig. 3From: Improved recovery of regional left ventricular function after PCI of chronic total occlusion in STEMI patients: a cardiovascular magnetic resonance study of the randomized controlled EXPLORE trialChanges in regional left ventricular function in segments in the CTO territory in Rentrop grade 2–3 collaterals versus grade 0–1 collaterals, comparing CTO PCI versus no-CTO PCI. Change in percentage segmental wall thickening (SWT) in all segments (a) and dysfunctional segments (b) in the CTO territory comparing Rentrop grade 2–3 collaterals versus grade 0–1 collaterals. Recovery of SWT was compared between baseline and 4 month follow-upBack to article page
