Left ventricular outflow tract after Kawashima intraventricular rerouting.
Left ventricular outflow tract obstruction is a concern in the long term after Kawashima intraventricular rerouting for Taussig-Bing anomaly. This study assessed the late results and left ventricular outflow tract dimensions after intraventricular rerouting for Taussig-Bing anomaly in 6 children. Age at operation ranged from 8 months to 7 years. The shortest distance from the tricuspid valve to the pulmonary valve ranged from 8 to 18 mm, which was 79%-139% of the normal aortic annulus diameter. All patients survived the operation, but one died of chronic heart failure 4 months after repair. Three patients had no left ventricular outflow tract obstruction 15 to 31 years after repair, and 2 had significant obstruction at 9 and 14 years. One patient underwent successful revision of the intraventricular baffle; the distance between the tricuspid and pulmonary valves was 16 mm (108% of the normal aortic annulus) although it had been 8 mm (79%) at the initial repair. Late results of intraventricular rerouting were considered favorable.
