In this regard we investigated the feasibility of epi-aortic Doppler measurements in order to calculate cardiac output.Methods: Epi-aortic cardiac output measurement was compared with Fick measurements as the gold standard in eight patients with a univentricular circulation after a Fontan-type operation.Results: The mean diameter of the aorta by epi-aortic measurement was 18 mm (range 14 to 25), by angiography 17 mm (range 10 to 24), correlation coefficient 0.88 (p &lt;&nbsp;0.05). The mean cardiac output by epi-aortic measurement was 2.8 l.min&minus;1 (range 1.2 to 6.3), by the Fick calculations 1.8 l.min&minus;1 (range 0.8 to 5.0). The correlation coefficient for cardiac output data in aortic diameters up to 20 millimeter in diameter was 0.55 (p&nbsp;&lt; 0.05).Conclusions: Epi-aortic Doppler measurement of cardiac output after Fontan type reconstructions could be applied in aortas up to 20 millimeter in diameter. A reasonable correlation with Fick calculations was found. This was supported by Bland&ndash;Altman plotting. The method is intrinsically invasive, but application and removal of the device were easy and no complications related to the system were observed. An important restriction is the often present abnormal anatomy, either congenitally or after surgery.Keywords: cardiac output, Fontan circulation, epi-aortic Doppler, extravascular Doppler Ad J J C BogersMartin van den BurgRonald ScheppJan KleinDove Medical PressarticleMedical technologyR855-855.5ENMedical Devices: Evidence and Research, Vol 2009, Iss default, Pp 27-29 (2009)
