PaCO 2 /R: partial pressure of carbon dioxide/respiratory quotient; LAV: left atrial volume; LVDD: left ventricular diastolic diameter; LVEF: left ventricular ejection fraction; PSP: pulmonary systolic pressure. In the present series, there was a tendency of the cTEE to detect HPS in a greater number of subjects compared with cTTE. This can be explained by the diagnostic criteria for HPS, which may vary according to gas exchange parameters. 14 Maybe the inclusion of a greater number of participants would have led to more significant results. 919
