Intraoperative ultrasound monitoring of banding of the pulmonary trunk: a new technique?
We report an intraoperative real-time echo/Doppler study of the hemodynamic effects of banding of the pulmonary trunk in complete transposition seven years after a neonatal Mustard procedure. The patient had developed severe right ventricular failure. To prepare the left ventricle for an arterial switch procedure, banding of the pulmonary trunk was performed. While tightening the band, we monitored the pressure drop produced by using real time continuous wave Doppler interrogation. After banding, we used combined M-mode and cross-sectional echocardiography to image the left changes induced in left and right ventricular dimensions, shape and function by the acute change in hemodynamics.
