From: Limitations of free-form-text diagnostic requisitions as a tool for evaluating adherence to appropriate use criteria for transthoracic echocardiography

AUC indication no. Description Number of requisitions (% of population)
58 Suspected cardiovascular source of embolus 162 (12.4)
1 Symptoms or conditions potentially related to suspected cardiac etiology 134 (10.3)
34 Initial evaluation when there is a reasonable suspicion of valvular or structural heart disease 72 (5.5)
