37 Predictive value of normal high-sensitivity troponin for significant coronary artery disease in new atrial fibrillation

Abstract

placed under-expanded stent and 11% had severely calcified ISR. Procedural success was high (94%), however, reasons for failure/abandonment included: (i) intra-procedural ischaemia with significant residual stenosis, (ii) prolonged procedural time, ischaemia and resistant stent under-expansion and (iii) prolonged procedural time, dissection with no-reflow, in the setting of a chronic total occlusion (CTO). Complications Included Coronary dissection (13%) of which the majority were successfully treated with conservative measures and coronary perforation (2%) which was treated with prolonged balloon inflation. At a mean follow up of 10 months, 23% underwent planned/staged-PCI, 4% underwent CABG and there were 2 (4%) deaths. There was a 51% reduction in CCS angina class from 2.9 (prior to IVL) to 1.4 (post IVL), p<0.00001. Conclusions The use of coronary IVL is a very effective percutaneous therapy for severe CAC. This cohort shows high procedural success with IVL and a significant reduction in CCS angina class at follow-up.
