VSD devices

  1. 1. VSD DEVICES
  2. 2. COMPLICATIONS OF VSD DEVICES (29% cases, mostly minor) • EMBOLISATION (2-5%) • ARRHYTHMIAS (mostly transient) • CONDUCTION DEFECTS (2-3% CHB) • AR/TR (9% mostly resolves within 6 months) • RESIDUAL LEAK (upto 60% cases with post MI VSD device closure) • LOCAL PUNCTURE SITE COMPLICATIONS
  3. 3. AMPLATZER MUSCULAR VSD DEVICE • SYMMETRIC • WAIST length 7 mm ,Discs exceed waist by 8 mm • Dacron fabric incorporated • Sizes 4-18 mm
  4. 4. AMPLATZER ASYMMETRIC VSD OCCLUDER • very short (1.5 mm) connecting waist to minimise contact with the tricuspid valve. • In its latest design the left sided disk extends 5 mm towards the apex (with a platinum marker) to lean firmly on the muscular septum and only 0.5 mm towards the aorta to avoid contact with the aortic valve • The right sided disk is 4 mm larger than the waist. • The prosthesis is filled with Dacron fabric to facilitate thrombosis. • Prostheses are available in sizes ranging from 4–12 mm at increments of 2 mm
  5. 5. AMPLATZER PERIMEMBRANOUS VSD DEVICES • Allows for placement that avoids interference with the aortic or atrioventricular valves • Devices range from 4 to 18 mm, in single mm increments • LV disk is 6 mm larger, RV disk is 4 mm larger than waist
  6. 6. AMPLATZER POST MI VSD DEVICE • Symmetric,Waist 10 mm, discs 10 mm larger • Sizes 16-24 mm(less than required!!) • Dacron incorporated • 20% have complete closure,60% have small residual leak,20% have moderate leak • 28% mortality at 30 days
  7. 7. POST MI VSD CLOSURE RESULTS Kaulfersch, Dähnert, Schuler, Thiele Minerv Cardioangiol 2007;55:693-701
  8. 8. MADE IN CHINA……!! • YATAI Scientific corporation • Polyester fabrics sewn in frame
  9. 9. LIFETECH • • • • Nitinol mesh Polyester Pure Stainless Steel tip e PTFE membrane
  10. 10. NIT OCCLUD VSD COIL • Novel attachment mechanism, 6 Fr delivery catheter • Controlled released coil similar to the PDA NitOcclud • Stiff distal loops covered with Dacron filaments • Distal coil diameter: 10, 12, 14, 18 mm • Prox coil diameter: 6, 6, 8, 10 mm
