Summary
The ReCross microcatheter, used in antegrade chronic total occlusion percutaneous coronary intervention (CTO PCI), demonstrated high success rates (96%) and efficiency in a recent study. This device shows promise for improving CTO PCI outcomes.
Area of Science:
- Cardiovascular Interventions
- Interventional Cardiology
- Medical Device Technology
Background:
- The antegrade approach is a primary technique for chronic total occlusion percutaneous coronary intervention (CTO PCI).
- Advancements in devices and strategies, including the hybrid algorithm, have improved CTO PCI success rates.
- The ReCross microcatheter, a novel device with dual lumens and multiple exit ports, has potential in antegrade CTO PCI but limited published efficacy data.
Purpose of the Study:
- To evaluate the efficiency and outcomes of the ReCross microcatheter in contemporary CTO PCI.
- To analyze the device's performance based on a predefined protocol and firsthand clinical experience.
Main Methods:
- A prospective study involving 118 patients undergoing CTO PCI at eight centers between June 2023 and April 2024.
- Patients were treated using a planned primary antegrade approach with an upfront ReCross microcatheter strategy.
- Data collected included procedural success, time, and complications.
Main Results:
- The ReCross strategy achieved a technical success rate of 96% in 118 patients, with 94% of cases successfully resolved.
- The average procedure time was 90 minutes, which is lower than reported in similar studies.
- No procedure-related mortalities occurred; one case of distal wire perforation was reported.
Conclusions:
- The ReCross microcatheter, when used with a dedicated algorithm in select cases, facilitates highly successful antegrade CTO PCI.
- Initial clinical experience indicates the device is effective and efficient for CTO PCI.
- Further investigation into the ReCross device's role in antegrade CTO PCI is warranted.

01:16Crossover Experiments
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
