One hundred and four were treated for dissecting and 44 for non-dissecting pathologies. Eighty-four received FET initially and 64 as an aortic redo procedure. Data were collected retrospectively using our center's dedicated aortic database as well as transthoracic echocardiographic reports of our cardiologists.<\/jats:p><jats:p>In the first weeks after FET implantation, dissection and non-dissection patients show a significant increase of mild valvular insufficiencies\u2014a significant decrease of ejection fraction is only seen in dissection patients but these changes do not stay significant during later follow-up. Patients who receive FET as an aortic redo procedure tend to have significantly larger left ventricular (LV) end-diastolic diameters and higher LV masses, however, in longitudinal analysis, there were no long-term negative effects in patients who received FET initially or as aortic redo.<\/jats:p><jats:p>In the first 2 years after implantation, FET has no echocardiographically measurable effect
