Ventricular Remodeling In Patients With Aortic Stenosis Assessed Echocardiography

Withdrawn

• Conditions: Aortic Stenosis

• Registration Number: NCT00774657
• Lead Sponsor: Lahey Clinic

Brief Summary

This preliminary study will compare the effectiveness of two-dimensional and three-dimensional echocardiographic measurements of wall thickness and left ventricular mass in patients with Aortic Stenosis

Detailed Description

This study will evaluate left ventricular patterns of remodeling and hypertrophy in patients with aortic stenosis, and compare two-dimensional echocardiography measurements (wall thickness) with three-dimensional echocardiography data(left ventricular mass). Along with a second objective to assess Doppler diastolic filling indices associated with the various patterns of left ventricular remodeling.

Previous studies(see reference list) were primarily derived from two-dimensional echo data set(based on wall thickness). Various patterns of left ventricular remodeling have been described in response to increased pressure overload.

Three-dimensional echocardiography is a relatively new technique that is being increasingly used in the Echocardiography Lab in selected patients. This technique holds promise of being more accurate for volume-related measurements than the standard 2-dimensional echocardiography techniques.
