Official title: Mechanisms and Therapeutics for Congenital Aortic Valve Disease
Funded at Research Inst Nationwide Children's Hosp · NIH-11310034 · Data updated 2026-11-12
This project develops medicines targeting the genetic and molecular causes of malformed aortic valves to help people born with bicuspid or other congenital valve problems avoid or delay surgery.

Who could benefit from this research
✓Could help
People born with bicuspid aortic valve or other forms of congenital aortic valve stenosis who are at risk of progressive valve narrowing would be the most relevant candidates.
✕Less likely to help
Patients whose valve narrowing is caused mainly by age-related calcific aortic stenosis or who already need immediate valve replacement are unlikely to benefit from these early-stage therapies.
What this research studies
From your point of view, the team looks at inherited gene changes linked to bicuspid and malformed aortic valves and how those changes alter valve cells. They follow specific pathways (including NOTCH1 and nitric oxide signaling) and study the role of GATA5 using animal models and human valve tissue. Lab experiments will be used to find molecular targets and test candidate drugs that might slow valve narrowing. Promising lab findings would be pushed toward steps needed for future clinical testing in patients.
Why it matters
Potential benefit: If successful, this work could produce medicines that slow or prevent progression of congenital aortic valve stenosis and reduce the need for valve surgery or replacement.
How similar studies have gone: Previous genetic and animal studies have established key roles for NOTCH1, GATA5, and nitric oxide pathways, but effective pharmacologic treatments for congenital aortic valve stenosis remain largely unproven.
