    A novel method assists the right ventricle using timed balloon catheter inflation in the pulmonary artery. This approach augments blood flow, unloads the right heart, and aids conditions like pulmonary hypertension.

    Area of Science:

    • Cardiovascular Science
    • Medical Devices
    • Surgical Innovation

    Background:

    • Effective methods for right ventricular assistance are currently limited.
    • The right ventricle plays a crucial role in cardiac function, and its failure has significant clinical implications.

    Purpose of the Study:

    • To introduce and evaluate a new approach for right ventricular assistance.
    • To demonstrate the feasibility of this method for independent use or during cardiac surgery.

    Main Methods:

    • Implementation of a novel approach involving timed inflation and deflation of balloon catheters.
    • Placement of catheters within the pulmonary artery to modulate distal flow.

    Main Results:

    • Augmentation of distal pulmonary arterial flow was achieved.

  • Successful unloading of the right side of the heart was demonstrated.

    • Conclusions:

    • The presented method offers a promising new option for right ventricular support.
    • This approach has potential applications in treating atherosclerotic heart disease, congenital heart disease, and pulmonary hypertension.
