2 discs connected together by waist that corresponds to size of VSD
Available in 4-18 mm waist sizes
Duct occluder
Designed to seal PDA
Conical shape to conform to PDA
Available in 5-16 mm diameters
Vascular plug
Used for embolization of peripheral arteries & veins
Alternative to coils
Device made from nitinol mesh & polyester fabric, which provide rapid occlusion & substrate for tissue ingrowth
Sizing balloon used to determine correct size device
Requires transesophageal or intracardiac echocardiography as well as fluoroscopic imaging during procedure
Can be repositioned & recaptured during placement
Very high closure rates (> 95%)
Indications for ASD closure device
Ostium secundum ASD
Clinical evidence of right ventricular (RV) volume overload
Left-to-right shunt of 1.5:1 or greater, or RV chamber enlargement
Contraindications
Sepsis within 1 month prior to implantation
Bleeding disorder or other contraindication to aspirin therapy after device placement
Intracardiac thrombi
Septal defect location < 5 mm from coronary sinus, atrioventricular valves, or pulmonary vein orifice
Nickel allergy (as nitinol contains nickel)
Follow-up
Requires endocarditis prophylaxis & antiplatelet/anticoagulation therapy for 6 months post implantation
Devices "conditional 6" to 3.0 Tesla magnet
