Three-dimensional echocardiography has become a gold standard to assess right ventricular (RV) function, and investigators plan to use 3D transesophageal echocardiography to assess RV function in 3 types of aortic valve replacement (AVR): surgical AVR (SAVR), mini-sternotomy AVR (mini AVR), and transcatheter AVR (TAVR).
Objective: Right ventricular (RV) function is known to be a critical factor to determine postoperative outcome in cardiac surgery, and echocardiography plays an important role in RV function assessment. In the previous studies, RV function was reported to be more reduced in surgical aortic valve replacement (SAVR) than transcatheter aortic valve replacement (TAVR), but its assessment was performed by 2-dimensional echocardiography. On the other hand, three-dimensional (3D) echocardiography has been the gold standard to assess RV systolic function (EF: ejection fraction), and its intraoperative…
Inclusion Criteria: * Adult patients over 18 years old * Patients who had SAVR, mini AVR, or TAVR Exclusion criteria: * Patients' refusal * Suboptimal echocardiography data for RVEF, RV size, RIMP, RVFAC, TAPSE, S', STE
With TEE package software, the investigators measure and calculate 3D TEE RVEF using mid esophageal 4 chamber view
