Assessing the severity of aortic stenosis.

The height of the "a" wave of the apexcardiogram was evaluated as a marker for critical aortic stenosis in patients over 40. Critical aortic stenosis was defined as an aortic valve area < .75 cm2 with no more than mild aortic insufficiency. Phonocardiograms and apexcardiograms were performed on 72 patients with catheterization proven aortic stenosis and on 14 normal controls, all over age 40. T...

Association between the severity of chest pain and the severity of mitral valve prolapse in children

Introduction: One of the causes of chest pain in children is mitral valve prolapse (MVP). This study aimed to investigate the association between the severity of chest pain and the severity of MVP. Materials and Methods: This cross-sectional study was designed on 103 children aged 7 to 18 years suffering from MVP along with chest pain. By using echocardiography, severity of MVP was assessed in ...

Assessment of aortic valve stenosis severity using intelligent phonocardiography.

Aortic valve resistance as an adjunct to the Gorlin formula in assessing the severity of aortic stenosis in symptomatic patients.

OBJECTIVES This study was conducted to determine the utility of aortic valve resistance in assessing the severity of aortic stenosis. BACKGROUND Assessment of the severity of aortic stenosis has traditionally employed hemodynamic data and the Gorlin formula to calculate the area of the aortic valve. Recently, flow dependence of the Gorlin formula has been identified and the accuracy of the fo...
