Aortic root dissection. Another cause of early systolic closure of the aortic valve.
An early systolic closure of the aortic valve was recorded in the echocardiogram in two patients with aortic root dissection. This sign, initially described in discrete subaortic stenosis and occasionally observed in mitral regurgitation and interventricular septal defect, has not so far been described in dissecting aneurysm of the aorta.
