Transesophageal echocardiography probe induced recurrent VF in a child with severe RV dysfunction: Report of a rare case

Abstract

The safety of transesophageal echocardiography (TEE) probes has been documented in pediatric patients (neonates, infants, and small children even\u2009<\u20092.5\u2009kg). The overall safety profile of TEE probe is quite favorable with a reported incidence of complications of 1%–3%. However, insertion of the TEE probe can induce vagal and sympathetic reflexes such as hypertension or hypotension, nonsustained ventricular and supraventricular tachyarrhythmias, or bradyarrhythmias (third degree heart block), and even angina and myocardial infarction. We hereby document a repeated intraoperative ventricular fibrillation precipitated by TEE probe in a 2‐year‐old, 10\u2009kg pediatric patient diagnosed with ostium secundum‐atrial septal defect, supravalvular pulmonary stenosis, and severe right ventricular dysfunction. The international review board approval or waiver and clinical trial registrations are not applicable for this case report publication.
