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 ...

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 ...

Constant improvements make the Ross procedure a safe aortic valve replacement option
Cardiac surgeons understand that innovation isn’t always about invention. Improving something can be just as transformative. So it shouldn’t come as a surprise that Boston Children’s cardiac surgery team is seeing lasting positive outcomes in patients after making adjustments over the years to the Ross procedure, a last-option treatment for aortic valve disease that hasn’t always been accepted by ...

Whether she’s embracing school, sports, or music, Lindsey shows how Williams syndrome can be managed
One of the first things Lindsey Franco will tell you is, “I like being me. I like being happy.” The 19-year-old has a lot to be happy about. She attends a post-high school transition program that helps young adults expand their social and life skills. There, she does all the things she enjoys, including playing ...

Mending injured hearts: Lessons from newborns?
When the heart is injured, as in a myocardial infarction, the damaged heart muscle cannot regenerate — instead, scar tissue forms. Cardiomyocytes, the heart muscle cells that generate contractile force, are lost for good. Yet, in mouse models, the hearts of newborns regenerate readily after injury. How are newborn hearts able to recover? What are ... Read More about Mending injured hearts: Lessons from newborns?
A surgeon’s last-minute trip to Sri Lanka reduces children’s wait for needed heart repair
Last year, Dr. Christopher Baird got an offer he couldn’t refuse — something that happens often as he travels the world to demonstrate the heart surgery techniques he has learned and developed at Boston Children’s Hospital. At a heart surgery symposium in India, Dr. Baird had just performed a complex type of aortic valve reconstruction ...
