In the United States, individuals born with single ventricle congenital heart disease (SVHD) and living with Fontan circulation face a significant challenge – there are currently no approved medications specifically designed to address their needs. However, there is a ray of hope on the horizon as the United States Food and Drug Administration (FDA) is actively evaluating the potential approval of Udenafil, a groundbreaking medication that has shown promise in enhancing exercise capacity for patients aged 12 and above with SVHD and Fontan circulation. This is a significant development, as Udenafil has the potential to become the sole medication available for this unique and deserving patient group.

The Fontan procedure, a surgical intervention performed on those with SVHD, reroutes blood flow in the heart, enabling individuals to survive with only one functional ventricle. While this procedure has improved outcomes for many, individuals with Fontan circulation often experience challenges in physical exertion, limiting their exercise capacity and overall quality of life. This is where Udenafil comes in, offering a glimmer of hope to those living with SVHD and Fontan circulation.

Udenafil, currently under FDA review, has shown promising results in clinical studies, demonstrating its ability to enhance exercise capacity among patients with SVHD and Fontan circulation. If approved, Udenafil will mark a groundbreaking milestone as the first-ever medication tailored to address the unique needs of this patient group.

We are at a crucial juncture where your support can make a significant impact. By joining us in advocating for the approval of Udenafil by the FDA, you can help ensure that individuals with SVHD and Fontan circulation finally have access to a medication that can improve their exercise capacity and enhance their overall quality of life. Together, we can make a difference and pave the way for better healthcare options for this underserved population.
