Successful recanalization of a calcified, collateral-poor LAD-CTO via repeat antegrade dissection and re-entry guided by intravascular ultrasound after prior subintimal plaque modification: a case report

Abstract Background Chronic total occlusion (CTO) of the left anterior descending artery (LAD) with poor collateral circulation poses significant procedural challenges. Subintimal plaque modification (SPM) followed by repeat antegrade dissection and re-entry (ADR) under intravascular ultrasound (IVU...
