Contemporary outcomes of chronic total occlusion percutaneous coronary intervention in Europe: the ERCTO registry.

Background: Percutaneous coronary interventions (PCI) of chronic total occlusions (CTO) have reached high procedural success rates thanks to dedicated equipment, evolving techniques, and worldwide adoption of state-of-the-art crossing algorithms.

Aims: We report the contemporary results of CTO PCIs performed by a large European community of experienced interventionalists. Furthermore, we investigated the impact of different risk factors for procedural major adverse cardiac and cerebrovascular events (MACCE) and trends of employment of specific devices like dual lumen microcatheters, guiding catheter extensions, intravascular ultrasound and calcium-modifying tools.

Gender differences in percutaneous coronary intervention for chronic total occlusions from the ERCTO study.

Background: Gender-specific data addressing percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) in female patients are scarce and based on small sample size studies.

Aims: We aimed to analyze gender-differences regarding in-hospital clinical outcomes after CTO-PCI.

Methods: Data from 35,449 patients enrolled in the prospective European Registry of CTOs were analyzed.

Retrograde Chronic Total Occlusion Percutaneous Coronary Interventions: Predictors of Procedural Success From the ERCTO Registry.

Objectives: The aim of this study was to identify independent predictors of procedural success after retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Background: Retrograde CTO PCI is an established technique, but predictors of success remain poorly understood.

Methods: A multivariable logistic regression model was used to analyze potentially important demographic, clinical, anatomical, and technical aspects of retrograde CTO PCI cases uploaded to the multicenter European CTO (ERCTO) Club Registry.

Acceptance and safety of femoral versus radial access for percutaneous coronary intervention (PCI): results from a large monitor-controlled German registry (QuIK).

Background: In 2015 and 2018, European Society of Cardiology guidelines for percutaneous coronary intervention (PCI) favoring radial access over femoral access were published. These recommendations were based on randomized trials suggesting that patients treated radially experienced reduced bleeding complications and all-cause mortality. We aimed to assess acceptance and results of radial access in a real-world scenario by analyzing all PCI cases in the Quality Assurance in Invasive Cardiology (QuIK) registry.

Microcatheters for antegrade recanalization of chronic total coronary occlusions: Feasibility and safety of the corsair - A retrospective registry-based single operator experience.

Background: The Corsair collateral channel dilator was designed for retrograde passage in cases of coronary chronic total occlusion (CTO). Its antegrade use is discouraged and the number of published studies regarding such use is limited. Our single-operator experience examines the feasibility and safety of the Corsair in antegrade recanalization of chronic CTOs in a large cohort.
