Interatrial Shunt Devices Market Size

Interatrial Shunt Devices Market Size

The global interatrial shunt devices market size was valued at around USD 3.8 billion in 2024 and is estimated to grow at 7% CAGR from 2025 to 2034. An interatrial shunt device is a medical device designed to create a controlled passage (or shunt) between the left atrium and the right atrium of the heart. This shunt allows blood to flow between the two atria, typically to reduce pressure imbalances or improve cardiac efficiency in specific medical conditions. These devices are often used to treat patients with certain forms of heart failure or pulmonary hypertension.

The market is primarily driven by the increasing prevalence of heart failure worldwide. According to the Journal of Cardiac Failure, nearly 6.7 million American aged over 20 years suffer from heart failure. The number is further estimated to increase to reach 8.5 million by 2030. As the global population ages and lifestyle-related risk factors become more common, the incidence of heart failure continues to rise. Interatrial shunt devices offer a minimally invasive treatment option for patients with heart failure, particularly those with preserved ejection fraction (HFpEF). These devices provide an alternative to traditional pharmacological therapies, which may have limited efficacy in certain patient populations.
 

Moreover, ongoing technological advancements in interatrial shunt devices are contributing to market growth. Improved device designs, materials, and implantation techniques are enhancing the safety and efficacy of these treatments. Additionally, the expanding body of clinical evidence supporting the use of interatrial shunt devices is increasing physician confidence and adoption rates. As more long term data becomes available and regulatory approvals are obtained in various regions, the market for these devices is expected to expand further, driving growth in the coming years.
