Role of myocardial strain and rotation for predicting prosthetic aortic valve stenosis

Pressure overload due to aortic stenosis leads to subclinical left ventricular (LV) dysfunction and global longitudinal strain (GLS) impairment even if ejection fraction is preserved. However, little is known about LV mechanics in aortic prosthetic valve (APV) stenosis. The study aimed to determine...

Zusammenfassung:	Pressure overload due to aortic stenosis leads to subclinical left ventricular (LV) dysfunction and global longitudinal strain (GLS) impairment even if ejection fraction is preserved. However, little is known about LV mechanics in aortic prosthetic valve (APV) stenosis. The study aimed to determine the role of myocardial strain and rotation in predicting prosthetic valve stenosis in mechanical APV patients. 60 patients with mechanical APV and 30 healthy individuals were evaluated. APV patients were analyzed in two groups; aortic valve mean gradient
