Validation of the coronary artery specific chronic total occlusion percutaneous coronary intervention angiographic difficulty scores in the PROGRESS-CTO registry.

Background: The J-CTO investigators recently developed angiographic difficulty scores for each of the three major coronary arteries in patients undergoing first-attempt chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in de novo occlusions.

Methods: We examined the performance of the individual J-CTO scores in a large multicenter registry.

Results: The CTO lesion location was as follows: right coronary artery (RCA) 3,805 (54%), left anterior descending artery (LAD) 2,303 (33%), and left circumflex (LCX) 935 (13%).

Iso-osmolar vs low-osmolar contrast agents for coronary optical coherence tomography: a blinded prospective randomized controlled study.

Background: The impact of contrast type on coronary optical coherence tomography (OCT) imaging has received limited research.

Methods: We conducted a blinded, prospective, single-center, randomized, controlled crossover study comparing iso-osmolar contrast media (IOCM) with low-osmolar contrast media (LOCM) in patients undergoing clinically indicated coronary OCT imaging. Patients were randomly assigned to undergo OCT imaging with either IOCM or LOCM as the initial contrast medium.

Burnout in cardiology: a narrative review.

The frequency of burnout is rising among cardiologists, affecting not only their well-being but also the quality of patient care. Computerization of practice, bureaucracy, excessive workload, lack of control/autonomy, hostile and hectic work environments, insufficient income, and work life imbalance are the main categories listed as contributing factors to cardiologists' burnout. Organization- and physician-directed interventions can be impactful; however, the effectiveness and feasibility of these interventions have rarely been assessed in cardiology.

Significance of Intercellular adhesion molecule-1 Lys496Glu gene polimorphism on plasma redox status regulation in laryngeal carcinoma.

Background: Intercellular adhesion molecule-1 (ICAM-1) is a surface glycoprotein important for tumor invasion and angiogenesis. The present research is conducted to investigate whether specific gene polymorphism of ICAM-1 K469E (rs5498) and plasma redox status could be associated with laryngeal cancer (LC) development. Since there is no clear evidence which investigates the relationship between ICAM-1 polymorphism and ROS-mediated plasma protein oxidation in LC, our study is the first significant contribution for investigating the relationship.

Sex differences in the well-being of interventional cardiologists.

Several studies suggest differences in burnout and coping mechanisms between female and male physicians. We conducted an international, online survey exploring sex-based differences in the well-being of interventional cardiologists. Of 1251 participants, 121 (9.

International survey of chronic total occlusion percutaneous coronary intervention operators.

Methods: We performed an online, anonymous, international survey of CTO PCI operators.

Adverse events with intravascular lithotripsy after coronary use: A report from the FDA MAUDE database.

Percutaneous coronary intervention (PCI) on heavily calcified lesions has been associated with more complications.1 Intravascular lithotripsy (IVL) was recently approved for treating de novo calcified coronary lesions based on excellent safety and efficacy on several studies, but there are limited "real world" outcomes. We conducted a comprehensive search of the MAUDE database between February 12, 2021, and February 28, 2023 using the manufacturer and brand name tabs with the keywords "Shockwave Medical" and "Shockwave," respectively.

Impact of target vessel on the procedural techniques and outcomes of chronic total occlusion percutaneous coronary intervention.

Background: There is limited information on the impact of the target vessel on the procedural techniques and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Methods: We analyzed the baseline clinical and angiographic characteristics and procedural outcomes of 11,580 CTO PCIs performed between 2012 and 2022 at 44 centers.

Results: The most common CTO target vessel was the right coronary artery (RCA) (53.

Atrial fibrillation and chronic total occlusion percutaneous coronary intervention outcomes: insights from the Progress-CTO registry.

Background: We examined the effect of atrial fibrillation on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Methods: We examined the baseline characteristics and procedural outcomes of 9,166 CTO PCIs performed at 39 US and non-US centers between 2012 and 2023.

Results: Atrial fibrillation was present in 1122 (12%) patients.

Frequency and outcomes of ad hoc chronic total occlusion percutaneous coronary intervention: insights from the progress-cto registry.

Background: Although discouraged, ad hoc chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is occasionally performed.

Methods: We examined the clinical, angiographic characteristics, and procedural outcomes of patients who underwent ad hoc CTO PCI in the Prospective Global Registry for the Study of CTO Intervention (PROGRESS-CTO, NCT02061436).

Results: Of the 10,998 patients included in the registry, 899 (8.

Incidence, treatment and outcomes of coronary artery dissection during percutaneous coronary intervention.

Background: Coronary artery dissection is a feared and potentially life-threatening complication of percutaneous coronary intervention (PCI).

Results: Between 2014 and 2019, unplanned coronary dissection occurred in 141 of 10,278 PCIs (1.

Contemporary In-Hospital Outcomes of Chronic Total Occlusion Percutaneous Coronary Interventions: Insights from the MENATA (Middle East, North Africa, Turkey, and Asia) Chapter of the PROGRESS-CTO Registry.

Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been rapidly evolving in different parts of the world. We examined the clinical and angiographic characteristics and procedural outcomes of 1,079 consecutive CTO PCIs performed in 1,063 patients at 10 centers in the Middle East, North Africa, Turkey, and Asia regions between 2018 and 2022. The mean age was 61 ± 10 years and 82% of the patients were men.
