Safety of Transesophageal Echocardiography to Guide Structural Cardiac Interventions

AbstractBackgroundDespite the widespread use of transesophageal echocardiography (TEE) to guide structural cardiac interventions, studies evaluating safety in this context are lacking.
ObjectivesThis study sought to determine the incidence, types of complications, and factors associated with esophageal or gastric lesions following TEE manipulation during structural cardiac interventions.
MethodsThis was a prospective study including 50 patients undergoing structural cardiac interventions in which TEE played a central role in guiding the procedure (mitral and tricuspid valve repair, left atrial appendage closure, and paravalvular leak closure). An esophagogastroduodenoscopy (EGD) was performed before and immediately after the procedure to look for new injuries that might have arisen during the course of the intervention. Patients were divided in 2 cohorts according to the type of injury: complex lesions (intramural hematoma, mucosal laceration) and minor lesions (petechiae, ecchymosis). The factors associated with an increased risk of complications were assessed.
ResultsPost-procedural EGD showed a new injury in 86% (n = 43 of 50) of patients, with complex lesions accounting for 40% (n = 20 of 50) of cases. Patients with complex lesions presented more frequently with an abnormal baseline EGD (70% vs. 37%; p = 0.04) and had a higher incidence of post-procedural dysphagia or odynophagia (40% vs. 10%; p = 0.02). Independent factors associated with an increased risk of complex lesions were a longer procedural time under TEE manipulation (for each 10-min increment in imaging time, odds ratio: 1.27; 95% confidence interval: 1.01 to 1.59) and poor or suboptimal image quality (odds ratio: 4.93; 95% confidence interval: 1.10 to 22.02).
ConclusionsMost patients undergoing structural cardiac interventions showed some form of injury associated with TEE, with longer procedural time and poor or suboptimal image quality determining an increased risk. Imaging experts performing this technique should be aware of the nature of potential complications, to take the necessary precautions to prevent their occurrence and facilitate early diagnosis and treatment.
