Clinical assessment of diastolic retrograde flow in the descending aorta for high-flow systemic-to-pulmonary artery shunting Tomomi Hasegawa, MD, Yoshihiro Oshima, MD, Toshikatsu Tanaka, MD, Ayako Maruo, MD, Hironori Matsuhisa, MD The Journal of Thoracic and Cardiovascular Surgery Volume 151, Issue 6, Pages 1540-1546 (June 2016) DOI: 10.1016/j.jtcvs.2016.02.028 Copyright © 2016 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 Doppler echocardiographic assessment of diastolic retrograde flow in the descending aorta. VTIs of systolic antegrade flow and diastolic retrograde flow were measured by tracing the curves above and below the baseline, respectively. VTI, Velocity-time integral.

Figure 2 Time-course changes in diastolic retrograde flow ratio in the descending aorta (dAo-RF ratio) after systemic-to-pulmonary artery shunting. Data of individual patients are represented with grey dots and lines. Data of patients who had postoperative adverse events related to high-flow shunting are separately represented with red dots and lines. Black dots and lines denote means and standard deviations. Black dashed lines denote 95% confidence intervals. ICU, Intensive care unit.

Figure 3 Time-course changes in diastolic BP, SpO2, shunt Vp, and serum lactate levels after systemic-to-pulmonary artery shunting. Data of individual patients are represented by gray dots and lines. Data for patients who experienced postoperative adverse events related to high-flow shunting are represented separately by red lines. Black dots and lines denote means and standard deviations. Black dashed lines denote 95% confidence intervals. BP, Blood pressure; Vp, peak flow velocity; SpO2, pulse oximeter oxygen saturation; ICU, intensive care unit.
