  Atrial Septal Defect Transcatheter Repair for Children

  Atrial septal defect (ASD) transcatheter repair is a procedure to fix a hole in the atrial septum. The atrial septum is a wall that separates the right and left upper chambers in the heart (atria). This hole is called an atrial septal defect or ASD. Your child will not need an incision in the chest wall for this procedure.

• Minimally Invasive Surgery

  Methods of Surgery

  An "open" surgery means cutting the skin and tissues so that the surgeon has a full view of the structures or organs involved. Minimally invasive surgery is a relatively new approach that allows the patient to recuperate faster with less pain. Not all conditions are suitable for this type of surgery.

• Mitral Valve Surgery

  Mitral Valve Replacement: Open

  An open mitral valve replacement is a surgery to replace a poorly working mitral valve with an artificial valve. The mitral valve, one of the heart's four valves, helps blood flow through the heart and out to the body. The mitral valve lies between the left atrium and the left ventricle. Your doctor will replace your poorly working mitral valve with an artificial valve. This will ensure that blood can flow into the left ventricle and then flow out to the body normally, without putting extra stress on the heart. The surgery is called “open” because it uses a traditional larger incision to expose the heart. This incision is larger than the incision used in minimally invasive mitral valve replacement surgery.

• Myasthenia Gravis

  Myasthenia Gravis

  Myasthenia gravis is a chronic autoimmune disorder in which antibodies destroy neuromuscular connections. This causes problems with communication between nerves and muscle, resulting in weakness of the skeletal muscles. Myasthenia gravis affects the voluntary muscles of the body, especially the eyes, mouth, throat, and limbs.
