Chronic Total Occlusion (CTO)


Long-term outcomes of patients with prior coronary artery bypass graft (CABG) surgery undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) have received limited study.
Coronary plaque modification via coronary atherectomy has evolved dramatically since its introduction as an important adjunct to PCI in the subset of patients with complex plaques.
We investigate the impact of Fielder XT-R and XT-A (Asahi Intecc) on antegrade wire escalation (AWE) crossing of Coronary CTO lesions. A total of 164 consecutive CTO lesions were treated with a primary AWE strategy using either guide wire as the starting wire regardless of lesion characteristics.
Hemodynamic support is increasingly utilized to avoid hemodynamic collapse during high-risk CTO-PCI. We retrospectively evaluated procedural and clinical outcomes in consecutive patients undergoing Tandem Heart assisted CTO-PCI at our institution.
We report a case of RA-induced fistula between the diagonal branch and the accompanying vein. Thus far, the patient has had no relevant symptoms; thus, no intervention has been undertaken. We will closely monitor the patient to determine future treatment.
