Against the Odds: Improving Survival for Children with Pulmonary Vein Stenosis

01/25/24 • 24 min

Dr. Christopher Petit is the co-director of the Children's Heart Center at NewYork-Presbyterian Morgan Stanley Children's Hospital and division chief of pediatric cardiology at Columbia University, and... a stubborn optimist. That optimism has made all the difference in his years of treating a rare heart disease in newborns: Pulmonary Vein Stenosis (PVS). Dr. Petit’s determination to better understand and treat PVS has led him and his team to make important breakthroughs in the field, including the use of sirolimus– an immune-targeted medication usually used for cancer treatments– as a systemic oral therapy to treat PVS, as well as the development of a hybrid surgical method for treating patients with severe disease, performed in collaboration with Dr. Emile Bacha. The results: drastically improved survival rates for his patients.

The Network Effect: Analyzing Brain Structures to Treat Depression

For any patient diagnosed with depression for the first time, the recommended course of treatment is the same: a medication like a selective serotonin reuptake inhibitor (SSRI), an evidence based psychotherapy, or both. But there is a large group of people for whom these treatments simply won't work. That’s where Dr. Conor Liston and his team focus. His work mapping the brain is helping doctors better understand where depression is impacting certain brain structures and what that means for the symptoms patients present. Dr. Liston’s work is focused on identifying how these symptoms impact patients' brains and using those findings to identify the best treatment approach. It also may eventually help detect the likelihood of depression in patients before they exhibit any symptoms.
