Biography
Yousif Ahmad, BMedSci, BMBS, PhD, MRCP, is an Assistant Professor of Medicine (Cardiovascular Medicine) and Associate Program Director of the Interventional Cardiology Fellowship at Yale Medicine. He specializes in treating problems related to the aorta, the main blood vessel that carries blood from the heart to the rest of the body. Dr. Ahmad uses advanced techniques, such as transcatheter aortic valve replacement (TAVR), to fix these issues with minimal impact on the body.
In addition to his clinical practice, Dr. Ahmad is a prolific researcher with numerous publications exploring various aspects of heart health and treatments for heart-related issues. His research interests include advanced imaging techniques for diagnosing heart problems, the impact of heart valve replacements on blood flow, and the relationship between heart health and other conditions, such as kidney problems and diabetes.
Dr. Ahmad is dedicated to improving the understanding of heart diseases and finding better ways to treat and prevent them. His expertise and commitment to patient care make him a valuable resource for those seeking treatment for heart-related issues.

Biography
Yousif Ahmad, BMedSci, BMBS, PhD, MRCP, is an Assistant Professor of Medicine (Cardiovascular Medicine) and Associate Program Director of the Interventional Cardiology Fellowship at Yale Medicine. He specializes in treating problems related to the aorta, the main blood vessel that carries blood from the heart to the rest of the body. Dr. Ahmad uses advanced techniques, such as transcatheter aortic valve replacement (TAVR), to fix these issues with minimal impact on the body.
In addition to his clinical practice, Dr. Ahmad is a prolific researcher with numerous publications exploring various aspects of heart health and treatments for heart-related issues. His research interests include advanced imaging techniques for diagnosing heart problems, the impact of heart valve replacements on blood flow, and the relationship between heart health and other conditions, such as kidney problems and diabetes.
Dr. Ahmad is dedicated to improving the understanding of heart diseases and finding better ways to treat and prevent them. His expertise and commitment to patient care make him a valuable resource for those seeking treatment for heart-related issues.
