Investigational drug(s) / intervention(s)
transcatheter closure of outlet VSDs with bioabsorbable occluders
transcatheter closure of outlet VSDs with bioabsorbable occluders: Transcatheter closure of outlet ventricular septal defects using a bioabsorbable occluder (Shape Memory Alloy Ltd, Shanghai, China). Implantation is performed via femoral/transthoracic approach under echocardiographic guidance following standard interventional protocols.
Study summary
This study aims to evaluate the efficacy and safety of transcatheter bioabsorbable occluder closure in patients with outlet-type ventricular septal defect (outlet VSD), with a focus on assessing its impact on aortic valve function.
