Outcome Measures

Primary Outcomes (1)

  • Leakage rate at 6 month post-procedure measured by ultrasound

    The heart defects should be totally closed by the patch. Any residual flow or leakage, measured by ultrasound, will be recorded. The percentage of the patients that show leakage post-procedure is the failure rate. The study is considered achieved its primary endpoint if the failure rate of the test device is non-inferior to the rate of the comparator device.

Study Arms (2)

Test Arm

EXPERIMENTAL

In Test Arm, the subjects will be implanted with test article - XenoSure patch. The interventions include: Open heart surgery to address the heart disease; Close the defects with XenoSure Patch

Procedure: Open heart surgery to address the heart diseaseDevice: Close the defects with XenoSure Patch

Control Arm

ACTIVE COMPARATOR

In Control Arm, the subjects will be implanted with comparator device - Polyester patch by Shanghai Chest Medical Technology Co. The interventions include: Open heart surgery to address the heart disease; Close the defects with Chest Polyester Patch

Procedure: Open heart surgery to address the heart diseaseDevice: Close the defects with Chest Polyester Patch

Interventions

The patient will first have open heart surgery to achieve access to the diseased site in the heart

Control ArmTest Arm

The heart defects, such as ASD (Atrial Septal Defect) or VSD (Ventricular Septal Defect ), are closed with LeMaitre XenoSure Patch.

Test Arm

The heart defects, such as ASD (Atrial Septal Defect) or VSD (Ventricular Septal Defect ), are closed with a Polyester Patch made by Shanghai Chest Medical Technology Co.
