Ventricular Remodeling In Patients With Aortic Stenosis Assessed Echocardiography
Ventricular Remodeling In Patients With Aortic Stenosis Assessed Echocardiography
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
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.
