Trial Parameters
Brief Summary
TAPSE, one of the methods for evaluating right ventricular systolic function; It is a bar parameter that can easily measure apex-basal shortening and provides specific information about global RV function. TAPSE/PASP can be calculated as load-independent parameters to evaluate RV function. Because RV function is sensitive to change in afterload, known as the RV-pulmonary circulation (PC) connection. This study aims to identify patients who are candidates for hypotensive events due to general anesthesia in a hemodynamically stable population.
