Why the study?
What is the echocardiographic motion pattern of the aortic valve in patients with ruptured right coronary sinus of Valsalva aneurysm compared to other non-rheumatic left ventricular outflow tract lesions?
What is the echocardiographic motion pattern of the aortic valve in patients with ruptured right coronary sinus of Valsalva aneurysm compared to other non-rheumatic left ventricular outflow tract lesions?
Identifies a novel echocardiographic sign (abnormal early systolic closure of the right coronary cusp) useful for diagnosing ruptured right coronary sinus of Valsalva aneurysm.
May not yet guide diagnosis of ruptured right coronary sinus of Valsalva aneurysm; leaves open specificity versus other LVOT lesions.
Echocardiographic examination of the aortic valve cusps has proved useful in the differential diagnosis of left ventricular outflow tract lesions. This paper presents a previously undescribed motion pattern of the aortic valve in 3 patients with ruptured right coronary sinus of Valsalva aneurysm. The right coronary cusp opened normally with the onset of systole, but demonstrated abnormal early systolic closure, with reopening in late systole. The noncoronary cusp moved normally. Following surgical correction in one patient, this early systolic closure was no longer present. Echocardiographic patterns in patients with membranous subvalvular aortic stenosis, idiopathic hypertrophic subaortic stenosis, and congenital aortic stenosis are compared.
