摘要

Background: Transoesophageal echocardiography (TOE) is a widely used imaging modality in ambulatory patients, with a reportedly low complication rate. TOE is frequently performed under conscious sedation. It is the imaging modality of choice for assessment of aortic valve morphology and size prior to trans-catheter aortic valve implantation (TAVI). However, the population of patients undergoing workup for TAVI differs from the general TOE population, as they have been turned down for conventional surgery due to high operative risk. Therefore, we sought to establish whether the complication rate for patients undergoing TOE as part of TAVI work-up is higher than the risk for the general TOE population.
