Over the past 2 decades, chronic total occlusion (CTO) percutaneous coronary intervention has developed into its own subspecialty of interventional cardiology. Dedicated terminology, techniques, devices, courses, and training programs have enabled progressive advancements. However, only a few randomized trials been performed to evaluate safety efficacy CTO intervention. Moreover, several published observational studies shown conflicting data. Part paucity clinical data stems from fact that...
The use of the Ostial Flash balloon (Ostial Corporation) has received limited study in aorto-ostial chronic total occlusion (CTO) percutaneous coronary artery intervention (PCI). authors evaluated outcomes a large CTO-PCI registry (PROGRESS-CTO, NCT02061436). was used 54 907 CTO PCIs 905 patients (6.0%). mean patient age 65.1 ± 10.7 and 80.6% were men, with high prevalence diabetes mellitus, hypertension, prior PCI, myocardial infarction. length 40.5 25.1 mm, 52.2% had moderate to severe...
ABSTRACT Background The effectiveness and safety of traditional versus dual lumen microcatheter (DLMC)‐assisted parallel wiring in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. Aims To compare wiring. Methods We compared the clinical angiographic characteristics outcomes DLMC‐assisted after failed antegrade (AW) a large, multicenter CTO PCI registry. Results Among 1353 PCIs with AW single wire, ( n = 1081) or 272) were utilized at...
Abstract Objectives To report clinical, angiographic characteristics, outcomes, and predictors of unsuccessful procedures in patients who underwent chronic total occlusion (CTO) percutaneous coronary interventions (PCI) Latin America. Background CTO PCI has been increasingly performed worldwide, but there is a lack information this region. Methods An international multicenter registry was developed to collect data on centers Patient, angiographic, procedural outcome were evaluated....
Abstract Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is a technically challenging procedure. In failed cases, plaque modification strategy (also known as “investment procedure”), defined the intentional dilation of subintimal space through CTO segment, can be applied. The typical device used in this regular angioplasty balloon (either semi‐ or noncompliant). Performing technique with drug‐coated (DCB) may facilitate staged procedure by promoting better vessel...
Abstract Objectives To evaluate the outcomes of subadventitial stenting (SS) around occluded stents for recanalizing in‐stent chronic total occlusions (IS‐CTOs). Background There is little evidence on SS IS‐CTO. Methods We examined IS‐CTO PCI at 14 centers between July 2011 and June 2017, compared them to historical controls recanalized using within‐stent (WSS). Target‐vessel failure (TVF) follow‐up was endpoint this study, defined as a composite cardiac death, target‐vessel myocardial...
Abstract Objectives We examined the incidence of periprocedural cardiac enzyme rise (PCER) [troponin T (TnT) or high‐sensivity (hs)TnT >5× upper limit normal (ULN)] and myocardial infarction (PMI), predictors PCER impact on longer‐term major adverse events (MACE) following hybrid chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Background PMI after CTO PCI, risk factors for its MACE are not fully understood. Methods Among 469 PCI cases performed between 01/2010...
To inform about contemporary PCI practice of in-stent (IS) chronic total occlusions (CTO) from a large international registry in Latin America.IS-CTO represent distinctive challenge for PCI, but literature is limited and restricted to high-resource regions the world.Patients undergoing CTO enrolled LATAM 42 centers eight countries were included. We analyzed demographics, angiographic, procedure technique, success postprocedural outcomes between IS-CTO non-IS-CTO PCI.From 1,565 patients was...
Background . Chronic total occlusion (CTO) plaque modification (CTO‐PM) is often used for unsuccessful CTO interventions. Methods A multicenter, prospective study included consecutive patients with failed recanalization. At the end of procedure, received either a conventional (CB) or drug‐coated balloon (DCB) CTO‐PM at operator’s discretion and underwent new attempt recanalization ∼3 months later. Results 55 were enrolled (DCB: 22; CB: 33), median age 66 years. The J‐score was 3, CCS angina...
The field of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has witnessed a dramatic evolution in the last decade. challenging nature CTO interventions involves regularly dealing with support-related issues, uncrossable/undilatable lesions, manipulation equipment subadventitial (also known as "subintimal") space, and treatment complications such perforation loss or entrapment. experience provided numerous techniques to creative operator facing challenges non-CTO PCI...
