Sustained benefit of left ventricular remodelling after valve replacement for aortic stenosis.

Background: Valve replacement for aortic stenosis (AS) determines negative ventricular remodelling. We used cross sectional and Doppler echocardiography to check how rapidly it occurs and to assess if these changes are sustained over time.

Methods: We evaluated in 34 patients subjected to aortic valve replacement for AS morphological and functional (ejection fraction and E:A ratio) left ventricular data by echocardiography prior to surgery and 2 postoperative studies: early after surgery (pQ1) and at mid-term evolution (pQ2).
