Assessment of site and severity in congenital aortic stenosis.

Assessment of site and severity in congenital aortic stenosis.

It has frequently been stated that congenital aortic valve stenosis cannot be distinguished with any confidence from discrete subvalvar aortic stenosis on clinical grounds, and that their separation rests on the results of hmmodynamic investigation and angiocardiography (Nadas, 1957; Ongley et al., 1958; Dotter et al., 1961; Braunwald et al., 1963; Engle and Ehlers, 1964). Our experience has le...

Assessment of Aortic Stenosis Severity by Cardiovascular Magnetic Resonance

Cardiovascular magnetic resonance (CMR) has become a valuable tool to corroborate aortic stenosis (AS) severity when echocardiography assessment is discordant. Moreover, CMR can provide useful complementary information about AS severity and hemodynamic markers. In particular, the use of advanced 4D flow CMR allows a comprehensive assessment of complex flow alterations produced by AS. This revie...

Assessment of aortic valve stenosis severity using intelligent phonocardiography.

Congenital valvar aortic stenosis. Natural history and assessment for operation.

Two hundred and eighteen patients with congenital valvar aortic stenosis aged between 1 and 25 years at presentation were followed for one to 26 years (average 8.7 years). Assessment of severity of aortic stenosis was essentially based on clinical findings including symptoms, the character of the pulse, and the behaviour of the second heart sound, management being further influenced by the degr...

Congenital Aortic Stenosis

mur, accompanied by a thrill, to the right of the sternum. On x-ray examination the most frequent manifestation was dilatation of the ascending aorta. Electrocardiographic evidence of left ventricular hypertrophy was found in 60 per cent. Nineteen patients have been operated upon with 2 deaths. The procedure has been tolerated amazingly well. Although it is too early to judge the results, all b...
