Background: Chronic total occlusion (CTO) is common in patients with diabetes mellitus. Data on the long-term outcomes after treatment of CTOs in this high-risk population are scarce.
Aim: To compare the long-term clinical outcomes of CTO revascularization either by coronary artery bypass graft (CABG) or successful percutaneous coronary intervention (PCI) versus optimal medical treatment (MT) alone in patients with diabetes.
Aims: Cryoballoon (CB) ablation has emerged as a reliable modality to isolate pulmonary veins (PVs) in atrial fibrillation. Ablation lesions and the long-term effects of energy delivery can be assessed by delayed-enhancement cardiac magnetic resonance (DE-CMR). The aim of the study was to compare the number, extension, and localization of gaps in CB and radiofrequency (RF) techniques in pulmonary vein isolation (PVI).
