Circulation. Cardiovascular Interventions, 2021 Supplemental Digital Content is available in the text. Background: Chronic total occlusions (CTO) occur in nearly 20% of coronary angiograms. CTO revascularization, either by percutaneous coronary intervention (PCI) or coronary artery bypass grafting ...

Microvascular dysfunction in the immediate aftermath of chronic total coronary occlusion recanalization [PDF]
, 2016 Objectives The aim of this study was to compare microvascular resistance under both baseline and hyperemic conditions immediately after percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) with an unobstructed reference vessel in ...

Journal of interventional cardiology, 2021 Intravascular lithotripsy (IVL) has been shown to be safe and effective for calcium modification in nonocclusive coronary artery disease (CAD), but there are only case reports of its use in calcified chronic total occlusions (CTO). We report data from an

The Hybrid Approach to Intervention of Chronic Total Occlusions [PDF]
, 2015 The "hybrid" approach to chronic total occlusion (CTO) percutaneous coronary intervention (PCI) was developed to provide guidance on optimal crossing strategy selection.

Advances in procedural techniques--antegrade. [PDF]
, 2014 There have been many technological advances in antegrade CTO PCI, but perhaps most importantly has been the evolution of the "hybrid' approach where ideally there exists a seamless interplay of antegrade wiring, antegrade dissection re-entry and ...

Journal of Interventional Cardiology, 2022 Background. The role of rotational atherectomy (RA) in contemporary percutaneous coronary intervention (PCI) is expanding to include certain chronic total occlusion (CTO) lesions. However, the long-term outcome of RA in CTOs is still unclear.

Medical therapy, percutaneous coronary intervention and prognosis in patients with chronic total occlusions [PDF]
, 2015 Objective There is little published data reporting outcomes for those found to have a chronic total coronary occlusion (CTO) that is electively treated medically versus those treated by percutaneous coronary intervention (PCI).

Temporal profile and mechanisms of the prompt sympathoexcitation following coronary ligation in Wistar rats [PDF]
, 2014 Our aim was to assess the timing and mechanisms of the sympathoexcitation that occurs immediately after coronary ligation. We recorded thoracic sympathetic (tSNA) and phrenic activities, heart rate (HR) and perfusion pressure in Wistar rats subjected to ...

Biomarkers of coronary endothelial health: correlation with invasive measures of collateral function, flow and resistance in chronically occluded coronary arteries and the effect of recanalization [PDF]
, 2016 Objectives: In the presence of a chronically occluded coronary artery, the collateral circulation matures by a process of arteriogenesis; however, there is considerable variation between individuals in the functional capacity of that collateral network ...

Adjunctive strategies in the management of resistant, 'undilatable' coronary lesions after successfully crossing a CTO with a guidewire. [PDF]
, 2014 Successful revascularisation of chronic total occlusions (CTOs) remains one of the greatest challenges in the era of contemporary percutaneous coronary intervention (PCI).
