Feasibility of Intraoperative 3-Dimensional Speckle-Tracking Echocardiography in Patients Undergoing Surgical Aortic Valve Replacement: A Prospective Observational Pilot Study
Authors' conclusion
3D speckle-tracking-based myocardial deformation analysis from intraoperative TEE datasets is feasible in >60% of patients with aortic valve stenosis. There were no statistically significant differences in GLS, CS, twist, or torsion between the intraoperative examinations.
