Loeys-Dietz Syndrome Symptoms often come on gradually with a decreased ability to exercise often occurring first. Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle.As a consequence, the cardiac muscle is Read full issue. Abdominal pain and hematuria. Background An atrial septal aneurysm (ASA) is a well-recognized abnormality of uncertain clinical relevance. Correspondence.
