    A new flexible cardiovascular endoscope allows clear visualization of heart and vascular structures. This innovative tool shows promise for diagnosing conditions like atrial septal defects with minimal patient risk.

    Area of Science:

    • Cardiovascular Medicine
    • Medical Device Technology
    • Diagnostic Imaging

    Background:

    • Traditional diagnostic methods for cardiovascular diseases can be invasive.
    • There is a need for minimally invasive tools for direct visualization of the cardiovascular system.

    Purpose of the Study:

    • To develop and evaluate a novel, slender, flexible cardiovascular fiberoptic endoscope.
    • To assess the safety and efficacy of this endoscope in diagnosing heart and vascular diseases.

    Main Methods:

    • Development of a 4.0 mm diameter, 120 cm long flexible cardiovascular endoscope.
    • Endoscopic procedures performed through peripheral vessels, similar to cardiac catheterization.
    • Application in 45 patients for diagnosis of various cardiovascular conditions.

    Main Results:

    • Clear visualization of the right side of the heart and vascular lumens was achieved.
    • The endoscope was successfully used in 45 patients for preoperative, intraoperative, and postoperative diagnoses.
    • No infections or apparent injuries to the cardiovascular system were observed.

    Conclusions:

    • The developed cardiovascular endoscope is a safe and effective adjunctive diagnostic tool.
    • This represents a significant advancement in minimally invasive cardiovascular diagnostics.
    • Further use is warranted to establish its role in routine clinical practice.
