Aria CV, Inc. is developing a medical device that treats pulmonary hypertension, a life-threatening disease with few therapeutic options. Pulmonary hypertension, or high blood pressure in the vessels that carry blood from the heart to the lungs, increases the workload on the heart. The increased workload leads to right heart failure, the ultimate cause of mortality in this disease. Patients are currently treated with drugs that can cost over $100,000 per year but are generally considered to have limited efficacy. Even with optimal drug therapy, the average survival time is on the order of six years, making pulmonary hypertension a tremendous unmet medical need. Aria CV, Inc. is developing a medical device that reduces the workload on the heart. Preclinical testing suggests the device has the potential to enhance both survival and quality of life of those suffering from pulmonary hypertension.
