Injected microbubbles could be a safe way to deliver emergency oxygen
For years, researchers and clinicians have been trying to find a way to rapidly deliver oxygen to patients when traditional means of oxygenation are difficult or ineffective during critical moments of cardiac or respiratory arrest. Sometimes, hypoxemia caused by airway obstruction or lung disease can be so severe that methods to boost low-oxygen levels (including ...

Clara now runs, dances, and sings along to Taylor Swift thanks to a new life-changing heart surgery
The time had finally come. Only two weeks after a transformative heart operation at Boston Children’s, 11-year-old Clara Portnoy stood in a sprinter’s starting position on an open stretch of grass during her school’s field day. Surrounded by classmates and teachers, she was ready to go. Born with a condition in which the structures on ...

Kiersten finds new purpose after care for life-threatening cardiomyopathy
Being just three miles away from her cardiac care team at Boston Children’s makes all the difference in the world to New Jersey native Kiersten Rock-Torcivia as she starts her sophomore year at Boston College. She is now closer to the specialists who help her manage a rare and life-threatening cardiomyopathy. Kiersten initially believed she ...

Shoring up heart muscle’s mini ‘managers’ to treat heart failure
Our heart muscle is studded with tiny dyads, intricately designed structures that manage incoming electrical signals and calcium release to coordinate our heartbeats. Could gene therapy help maintain dyads’ structure and boost the function of failing hearts? A new study suggests it can. “We know that in heart failure from many causes, dyads become disorganized,” says ... Read More about Shoring up heart muscle’s mini ‘managers’ to treat heart failure
Finding a possible genetic treatment for rare arrhythmias
Variants in a gene that plays a key role in heart function can cause potentially life-threatening arrhythmia syndromes known as calmodulinopathy. Calmodulinopathy is rare and causes arrhythmias that are poorly treated by current options. Boston Children’s cardiologist William Pu, MD, believes he has found a promising custom genetic treatment: antisense oligonucleotides that deplete the disease-causing gene product. ...

Jack had a first-of-its-kind surgery with the aim of making it his last
Jack Mangan loves fire trucks. He also loves monster trucks. So you can imagine his excitement about those two things being mashed up as a toy: a fire truck on top of a monster truck. The 4-year-old has an extensive collection of miniature hybrid monster trucks — one has a shark on top; another Scooby-Doo ...

Eight years of preparation for a surgical first: a partial heart transplant
Boston Children’s cardiac surgeons have an overriding goal for each patient: If possible, repair their congenital heart defect (CHD) — rather than replace any native heart tissue. Preserving heart tissue often leads to a speedier and more complete recovery and longer-lasting cardiac function. Sometimes, though, a patient’s valve tissue is beyond repair and a bioprosthetic or mechanical replacement valve ...

Ted Williams, chocolate milkshakes, and a pioneering heart team: What Bruce remembers about his heart surgery 65 years later
Bruce Chansky was the star of his neighborhood after he had heart surgery at Boston Children’s. It was 1959, a time when a child having heart surgery wasn’t common — it was newsworthy. Eleven-year-old Bruce was featured in his hometown newspaper, which only furthered his celebrity in Beverly, Massachusetts. Friends, neighbors, and strangers all wanted ...

Healing the heart, mind, and spirit
For most of her life, Siena Tancredi worried about her heart beating too fast. She has long QT syndrome, an inherited condition that affects the heart’s electrical rhythm and can cause fast, erratic heartbeats. From the time she was diagnosed at age 10 and into adulthood, she avoided any situation that would potentially cause her heart ... Read More about Healing the heart, mind, and spirit
Mitochondrial transfer restores heart muscle — but how?
Transferring mitochondria from a patient’s healthy skeletal muscle to damaged, ischemic heart tissue has been shown to restore heart muscle, increase energy production, and improve ventricular function. After pioneering preclinical work by James McCully, PhD, at Boston Children’s Hospital about a decade ago, cardiac surgeons led by Sitaram Emani, MD, have been testing it as ...
