Does real-time MRI guidance allow for successful transcatheter closure of atrial septal defects and immediate assessment of cardiac volumes in a swine model?
Real-time MRI guidance is feasible for transcatheter ASD closure and allows for immediate assessment of treatment effects on cardiac volumes in a swine model.
