Arm && Interventions

Group	Intervention	Description
Control Arm	Close the defects with Chest Polyester Patch	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
Test Arm	Open heart surgery to address the heart disease	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
Test Arm	Close the defects with XenoSure Patch	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
Control Arm	Open heart surgery to address the heart disease	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

Primary Outcome Measures

Name	Time	Method
Leakage rate at 6 month post-procedure measured by ultrasound	6 months	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.
