چکیده

AIM To investigate the rates and determinants of success of repeat percutaneous coronary intervention (PCI) following an initial failed attempt at recanalising the chronic total occlusions (CTO) percutaneously. METHODS In 445 consecutive first attempt CTO-PCI procedures in our institution, procedural failure occurred in 149 (33.5%). Sixty-four re-PCI procedures were performed in 58 patients (39%) all had a single CTO. Procedural and outcome data in the re-PCI population was entered into the institutional database. A retrospective analysis of clinical, angiographic and procedural data was performed. RESULTS Procedural success was achieved in 41 (64%) procedures. Univariate analysis of clinical and angiographic characteristics showed that re-PCI success was associated with intravascular ultrasound (IVUS) guidance (19.5% vs 0%, P = 0.042), while failure was associated with severe calcification (30.4% vs 9.7%, P = 0.047) and a JCTO score > 3 (56.5% vs 17.1% P = 0.003). Following multiple regression analysis the degree of lesion complexity (J-CTO score > 3), IVUS use, involvement of an experienced CTO operator and LAD CTO location were significant predictors of successful re-PCI. Overall the complication rate was low, with the only MACCE two periprocedural MI's neither of which required intervention. CONCLUSION Re-PCI substantially increases the overall success rate of CTO revascularization. Predictors of re-PCI success included the use of IVUS, the involvement of an experienced CTO operator in the repeat attempt and the location of the CTO.

Initial Experience of Retrograde Wire Approach in Coronary Chronic Total Occlusion Intervention

BACKGROUND AND OBJECTIVES Retrograde wire approach has been emerged as a useful tool to enhance success rate in coronary chronic total occlusion (CTO) intervention. Therefore, we tried to report the initial experience of retrograde approach and its clinical implication on CTO intervention. SUBJECTS AND METHODS From February 2007 to July 2008, retrograde approaches were performed in 28 patient...

Success, safety, and mechanisms of failure of percutaneous coronary intervention for occlusive non-drug-eluting in-stent restenosis versus native artery total occlusion.

We compared the procedural success, mechanism of failure, and safety of percutaneous coronary intervention in 235 procedures for de novo chronic total occlusions with 78 procedures for chronic occlusive in-stent restenosis. Despite similar rates of procedural success and safety profile, angiographic predictors of successful percutaneous coronary intervention for de novo chronic total occlusions...

Procedural outcomes and long-term survival among patients undergoing percutaneous coronary intervention of a chronic total occlusion in native coronary arteries: a 20-year experience.

OBJECTIVES The study compared procedural outcomes and long-term survival for patients undergoing percutaneous coronary intervention (PCI) of a chronic total coronary artery occlusion (CTO) with a matched non-CTO cohort to determine whether successful PCI of a CTO is associated with improved survival. BACKGROUND Percutaneous coronary intervention of a CTO is a common occurrence, and the long-t...

Long-term MACCE Rate after Retrograde Compared to Antegrade Recanalization of Chronic Total Coronary Occlusions

Background: The recanalization success rate of chronic total occlusion (CTO) percutaneous coronary interventions (PCI) can be increased by the retrograde approach. However, the long-term outcome of patients undergoing retrograde procedures is unknown. Aim: We aimed to evaluate the long-term MACCE (major adverse cardiac and cerebrovascular event) rate (death, myocardial infarction, coronary arte...

Intracoronary fibrin-specific thrombolytic infusion facilitates percutaneous recanalization of chronic total occlusion.

OBJECTIVES We sought to investigate the benefit, predictors of procedural success, and safety of pre-procedural intra-coronary fibrin-specific lytic infusion (ICL) in patients with failed prior percutaneous coronary intervention (PCI) for chronic total occlusions (CTO). BACKGROUND Percutaneous coronary intervention for CTO remains a challenge with a high incidence of procedural failure second...
