Normal anatomy of fetal heart- color Doppler ultrasound:

This color Doppler ultrasound video clip of the normal fetal heart, shows the flow across the foramen ovale, from the right atrium to the left atrium (seen in red). RA= right atrium, LA= left atrium, LV= left ventricle, RV= right ventricle. This was a normal 3rd trimester fetus.                                                                  

This B-mode ultrasound video clip shows the fetal heart in a 4 chamber view, with the the foramen ovale in the interatrial septum. Note the valve of the foramen ovale bulging into the left atrium as blood gushes from the fetal right atrium to left atrium. As pressure builds in the left atrium, after birth, the valve leaflet of the foramen ovale presses against the foramen, and closes this opening.
Another video clip of the normal mobility of the fetal foramen ovale valve (see below). The arrow heads point to the foramen ovale valve.

  1. After 6 months of offering stem cell therapy in combination with the venous angioplasty liberation procedure, patients of CCSVI Clinic have reported excellent health outcomes. Ms. Kasma Gianopoulos of Athens Greece, who was diagnosed with the Relapsing/Remitting form of MS in 1997 called the combination of treatments a “cure”. “I feel I am completely cured” says Ms. Gianopoulos, “my symptoms have disappeared and I have a recovery of many functions, notably my balance and my muscle strength is all coming (back). Even after six months, I feel like there are good changes happening almost every day. Before, my biggest fear was that the changes wouldn’t (hold). I don’t even worry about having a relapse anymore. I’m looking forward to a normal life with my family. I think I would call that a miracle.”
    Other recent MS patients who have had Autologous Stem Cell Transplantation (ASCT), or stem cell therapy have posted videos and comments on YouTube. www.youtube.com/watch?v=jFQr2eqm3Cg.
    Dr. Avneesh Gupte, the Neurosurgeon at Noble Hospital performing the procedure has been encouraged by results in Cerebral Palsy patients as well. “We are fortunate to be able to offer the treatment because not every hospital is able to perform these types of transplants. You must have the specialized medical equipment and specially trained doctors and nurses”. With regard to MS patients, “We are cautious, but nevertheless excited by what patients are telling us. Suffice to say that the few patients who have had the therapy through us are noticing recovery of neuro deficits beyond what the venous angioplasty only should account for”.
    Dr. Unmesh of Noble continues: “These are early days and certainly all evidence that the combination of liberation and stem cell therapies working together at this point is anecdotal. However I am not aware of other medical facilities in the world that offer the synthesis of both to MS patients on an approved basis and it is indeed a rare opportunity for MS patients to take advantage of a treatment that is quite possibly unique in the world”.
    Autologous stem cell transplantation is a procedure by which blood-forming stem cells are removed, and later injected back into the patient. All stem cells are taken from the patient themselves and cultured for later injection. In the case of a bone marrow transplant, the HSC are typically removed from the Pelvis through a large needle that can reach into the bone. The technique is referred to as a bone marrow harvest and is performed under a general anesthesia. The incidence of patients experiencing rejection is rare due to the donor and recipient being the same individual.This remains the only approved method of the SCT therapy.
