Novel transoesophageal echocardiographic views attain superior incident angles for tricuspid, but not pulmonary, valvular Doppler interrogation

Abstract

For accurate spectral Doppler valvular evaluation, intraoperative sonographers must use transoesophageal echocardiographic (TOE) views that offer optimal incident angles. We hypothesised that views added to the 2013 American Society of Echocardiography/Society of Cardiovascular Anesthesiologists (ASE/SCA) standard views and other novel views we have described of the tricuspid (TV) and pulmonary valves (PV) offered superior incident angles to those included in the original 1999 ASE/SCA recommendations for comprehensive intraoperative TOE examination. We compared the acquisition feasibility and incident angles obtained by these views in 62 patients undergoing elective cardiac surgery, who rece..
