THE IMPACT OF GRADIENT AND FLOW ON THE OUTCOMES OF TAVR IN SEVERE AORTIC STENOSIS WITH PRESERVED LEFT VENTRICULAR EJECTION FRACTION

Background While transaortic flow and gradient are important determinant of prognosis in patients with severe AS treated medically or with surgical aortic valve replacement; it is unclear whether these echocardiographic values are still predictive of outcomes in patients with severe aortic stenosis with preserved ejection fraction who are undergoing TAVR is less defined. At baseline there was no significant difference in baseline characteristics in regards of age, race, gender, or baseline characteristics including hypertension, hyperlipidemia, diabetes or coronary artery disease.
