Effect of the degree of tricuspid regurgitation on cardiac output measurements by thermodilution

Popis výsledku v původním jazyce

To determine the relationship between the degree of tricuspid regurgitation (TR) and accuracy of cardiac output measurement by thermodilution in mechanically ventilated patients. We examined 27 patients (not undergoing cardiac surgery): 8 with no or 1stdegree TR, 9 with 2nd degree, and 10 with 3rd degree TR. All patients were measured twice using simultaneously transesophageal echocardiography and pulmonary artery catheter for cardiac output. Continuous Doppler measurements were taken in the left ventricular outflow tract at the level of the aortic valve. Cardiac output was calculated by multiplying the velocity-time integral by aortic valve area and heart rate. Simultaneous pulmonary artery catheter measurements were taken averaging the results of the three 10-cc boluses of iced saline. The difference between the methods was 0.5+/-1.1 l/min (mean +/- 2 SD) in patients with no or 1st degree TR (r=0.96), 0.8 2.0 l/min in those with 2nd degree TR (r=0.92), and 1.9+/-2.3 l/min in those w
