Abstract
Chronic total coronary occlusions (CTO) occur in up to 50 % of patients with coronary artery disease by angiography. In CTO-patients, clinically significant arrhythmia is potentially important and insufficiently investigated. Therefore, the purpose of the CTO-ARRHYTHMIA study was to investigate the incidence of loop recorder detected clinically significant arrhythmias and the effect on arrhythmias of revascularization by CTO-PCI. The study is an independent sub-study of the NOrdic-Baltic Randomized Registry Study for Evaluation of PCI in Chronic Total Coronary Occlusion (NOBLE-CTO); ClinicalTrials.gov Identifier NCT03392415. NOBLE-CTO prospectively collects procedural data, quality of life measures, echocardiographic and cardiac MRI findings before and after treatment as well as clinical outcomes in all CTO patients that may be treated by PCI.
