3D Printing Help Surgeons Treat Complicated Heart Defects

A recent study found that supplementing x-rays, MRI, and ultrasounds with a 3D-printed model of a patient's heart helped surgeons perform delicate procedures to repair severe abnormalities.

Most heart surgeons rely on x-ray, MRI, and ultrasound technology to help them prepare for a complicated procedure. According a report by the American Heart Association, new research suggests that 3D-printed models of a patient's heart would boost a surgeon's ability to treat heart abnormalities and birth defects. Unlike the aforementioned trio of resources, a 3D-printed heart model would allow doctors to examine in great detail "complex structural complications in the heart’s chambers that occur when heart disease is present at birth."


From the report:

"Researchers used an inexpensive plaster composite material to create heart models of a 9-month-old girl, 3-year-old boy and a woman in her 20s all of whom had complex congenital heart defects. After studying the models and traditional images, surgeons successfully repaired severe heart abnormalities in all three patients."

...

“'With 3D printing, surgeons can make better decisions before they go into the operating room,' said Matthew Bramlet, M.D., study lead author and assistant professor of pediatric cardiology and director of the Congenital Heart Disease MRI Program at the University of Illinois College of Medicine in Peoria. 'The more prepared they are, the better decisions they make, and the fewer surprises that they encounter.

'When you’re holding the heart model in your hands, it provides a new dimension of understanding that cannot be attained by 2D or even 3D images. What once was used to build trucks, we’re using now to build models of hearts.'”

'Upstreamism': Your zip code affects your health as much as genetics

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."

Sponsored by Northwell Health
  • Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
  • Patients from low-income neighborhoods are most at risk of negative health impacts.
  • Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.

Meet the Bajau sea nomads — they can reportedly hold their breath for 13 minutes

The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.

Culture & Religion
  • The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
  • Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
  • Unfortunately, many disparate factors are erasing the traditional Bajau way of life.

Surprising Science
  • Fewer than 50 people worldwide have 'golden blood' — or Rh-null.
  • Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.
  • It's also very dangerous to live with this blood type, as so few people have it.
