Outcomes of Percutaneous Antegrade Intraluminal Coronary Intervention of Chronic Total Occlusion With Remote Surgical Backup

Percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) is not favored in facilities without on-site surgical backup. We reviewed outcomes of patients who had CTO intervention with remote surgical backup in our institution. All patients who underwent attempted antegrade intraluminal CTO PCI from January 2013 to July 2017 were analyzed. Twenty cases (18 patients, 58.1 +/- 7.0 years, 70% males) were identified. Procedure was successful in 85% (17 of 20). There were 2 nonflow limiting dissections and 1 wire perforation. Two patients had post-PCI myocardial infarction. There was no cardiac death, myocardial infarction, target vessel revascularization, or stroke at 30 days and at mean follow-up of 19.5 +/- 13.7 months. There were 4 rehospitalizations for angina requiring repeat angiogram in 3 cases: 2 without intervention, and 1 referred for coronary artery bypass grafting. Careful attempt at antegrade intraluminal CTO intervention done at a center with remote surgical backup is feasible in selected patients.
