  1. Heart Valves for Congenital Heart Disease Patients Vathana Ngeth Biomedical Engineering University of Rhode Island

  2. What is congenital heart disease? • Problems of the heart present at birth • Most common birth defect • 8 out of every 1000 newborns affected • No types of prevention http://www.healthcentral.com/common/images/1/18133_11388_5.jpg

  3. What is aortic valve stenosis? • Allows for the blood to flow out of the heart Issues: • Stiffening • Thickening • Valve fusion Symptoms: • Causes chest pain • Poor circulation • Easily fatigued https://carmenwiki.osu.edu/download/attachments/15439430/aortic%20stenosis-1.jpg

  4. Biological Valves • Animal tissues or donors • Used the least • Short life duration http://www.reidhealthcare.ie/images/cardiac-surgery/bhv1_web.png • No need for blood thinners • Lower risk of thrombi http://www.clemson.edu/media-relations/archive/newsroom/multimedia/images/2008_images/september/pigvalve.jpg

  5. Caged Ball Valve http://bloximages.chicago2.vip.townnews.com/tdn.com/content/tncms/assets/editorial/b/15/edf/b15edf66-da7f-11df-b4d8-001cc4c03286-revisions/4cbbe6ff3a85e.image.jpg http://www.pages.drexel.edu/~nag38/Images/ball_clip_image001.jpg http://www.sciencephoto.com/image/278433/530wm/M5610088-Artificial_heart_valve-SPL.jpg

  7. Bi-leaflet Valve http://www.pages.drexel.edu/~nag38/Images/bil_clip_image001.jpg http://www.lbl.gov/ritchie/Programs/BIO/bileaflet.jpg

  8. What is the procedure? • Too severe for repair (minimally invasive surgery) • Replacement surgery • Incisions in the chest through skin and muscle • Open heart • Endoscopy • Assistance of lung-heart machine • Average duration 3-6 hours http://www.umm.edu/graphics/images/en/22868.jpg

  9. Complications • Extreme stress on the body • Restarting the heart • Fluid buildup around the cardiac cavity • Proper valve function • Very high risk of infection • Blood clots

  10. Patient’s future • Biological Heart Valve • Another major surgery • Mechanical Heat Valve • Blood thinner medication • Regular heart check-ups • Limited to no physically rigorous activity

  11. Future of heart valves and procedures • Development of better materials • Stronger for less degradation • More fluid dynamic valves • Better techniques to reduce pain and recovery time
