Abstract

Abstract: Funding Acknowledgements: Type of funding sources: None. Background/Introduction: Transesophageal echocardiography (TEE) has long provided excellent diagnostic imaging of left-sided valvular pathology with an excellent safety profile; however, recent data has suggested an increased risk of injury related to TEE guidance. Purpose: This study aims to evaluate the incidence and nature of TEE-related oropharyngeal or esophageal complications in patients undergoing TEE-guided structural heart procedures and identify associated risk factors. Methods: We reviewed consecutive patients undergoing TEE-guided structural heart procedures from 2005-2020. All procedures were performed under general anesthesia. TEE-related oropharyngeal or esophageal complications were defined as those occurring within 30 days of the procedure resulting in i) persistent dysphagia, odynophagia, or upper gastrointestinal bleeding requiring prolonged endotracheal intubation, therapeutic endoscopic or surgical intervention, or diagnostic imaging that demonstrated oropharyngeal or esophageal injury. ii) upper gastrointestinal bleed requiring transfusion, hemodynamic compromise warranting mechanical or pharmacologic support; or iii) oropharyngeal or esophageal complications leading to death. For multivariate analysis, all variables with a p < 0.15 at univariate analysis were included in the model. Results: Among 1229 adult patients undergoing TEE-guided structural heart procedures between 2005-2020, 274 underwent a transcatheter aortic valve replacement (TAVR) with the remaining 955 undergoing either mitral valve transcatheter edge-to-edge repair (mTEER, n = 278), mitral paravalvular leak closure (PVLC, n = 354), mitral valve-in-valve replacement (VIV, n = 41), or left atrial appendage closure (LAAO, n = 282). Of these, 6 (0.5 %) had TEE-related complications; 0% TAVR, 0% VIV, 0.36% LAAO, 0.28% PVLC, 1.41% mTEER (p = 0.14). Of the six patients with complications 3 required at least one day of prolonged tracheal intubation and one a blood transfusion. None required surgical repair. Factors associated with increased complication risk (Table) included a prior history of gastrointestinal bleed (Odds ratio 5.44 [0.98-30.04; p = 0.05]) and longer procedural time (OR per 30 min 1.15 [1.01-1.31, p = 0.03]). Patients undergoing mTEER had an increased risk of complication (OR 6.76 [1.23-37.1 p = 0.03]) and longer procedural time (OR per 30 mins 1.15[1.01-1.31, p = 0.04]) compared to other all other procedures. Conclusion(s): In a large series of patients undergoing cardiac structural interventions under general anesthesia with TEE-guidance, rates of TEE-induced injury were low. Risk of oropharyngeal or esophageal complications was increased with longer procedure times, prior gastrointestinal bleeding history, increased age, increased pre-procedural creatinine, procedural type being mTEER and in male patients, lower height.
