THE LEFT VENTRICULAR REMODELING AFTER MECHANICAL AORTIC VALVE REPLACEMENT Clinical Trial
Official title:
Long-Term Effects of Aortic Valve Mismatch on Functional Ability and Remodeling the Left Ventricular After Aortic Valve Replacement Mechanics
The real impact of the existence of an aortic valve mismatch after aortic valve replacement in various studies conducted so far is a source of controversy. There is currently no long-term impact of the aortic valve mismatch on the reversal of left ventricular remodeling and its impact functional.To evaluate these effects of aortic valve mismatch on abilities to the effort, the quality of life and the regression of left ventricular hypertrophy long term after a aortic valve replacement, conducting a new study is fundamental. This study is even more essential in patients with a young life expectancy theoretical long and physical activity.Our study aims to determine whether the existence of an aortic valve mismatch has an influence on: The functional capacity to the effort by measuring the maximum oxygen consumption during a stress test (VO2 max) The reversal of left ventricular remodeling (cardiac ultrasound doppler), diastolic dysfunction (cardiac ultrasound and Doppler measurement Brain Natriuretic Peptide (BNP). This study will analyse these data in patients who received youth a VAN by mechanical aortic valve prosthesis.
