Clinical Impact of the 'Delta-Aortic Valve Gradient', the Reduction in the Mean Aortic Valve Pressure Gradient After Transcatheter Aortic Valve Implantation, on Left Ventricular Ejection Fraction Improvement and Long-Term Mortality in Patients With Severe Aortic Stenosis and Left Ventricular Dysfunction
{{output}}
Background: The relationship between the reduction in aortic valve pressure gradient (AVG) after transcatheter aortic valve implantation (TAVI) and improvements in left ventricular ejection fraction (LVEF) or long-term survival r... ...
