Valve Replacement

 Removal and replacement of a defective heart valve with an artificial or
biological valve.

 Invasive procedure performed under general anesthesia, a large cut is made
to the breastbone to reach the heart and aorta. The heart is stopped and the
CS is connected to a heart-lung bypass machine to continue oxygenating the
blood.




                                         This image shows an artificial heart
                                        valve being inserted, the plastic
                                        tubes on the right are connected to a
                                        heart-lung bypass machine. Artificial
                                        valves are more durable than biological
                                        replacements but the patient will need
                                        to continuously take blood-thinning
                                        medication for life.
Angioplasty
Also known as Percutaneous Coronary Interventions [PCI], Balloon
Angioplasty, Coronary Artery Balloon Dilation, and percutaneous
transluminal coronary angioplasty (PTCA).

    Minimally invasive surgical procedure to correct localized narrowing
     of artery.

    Involves the insertion of a balloon catheter through the skin into
   the coronary artery, the balloon is dilated to help widen the vessel
   and compress plague blocking the artery.




                                      Often times a stent is implanted during
                                     the procedure to help the artery remain open
                                     and decrease the chance of another blockage
Coronary Artery Bypass Graft

 Open-heart procedure where (usually) the saphenous vein (leg vein) is
grafted onto the aorta and coronary artery to reroute blood around a blockage.

 The coronary arteries supply blood to the heart muscle, a significant
blockage will lead to death of the heart muscle. This is a myocardial infarction, or
heart attack.

                                       This picture illustrates a single-bypass graft.
                                      1-5 coronary arteries can be bypassed,
                                      depending on the number of blockages.
