Right and left ventricular function after the Mustard procedure in transposition of the great arteries.

摘要: Right and left ventricular function was assessed at cardiac catheterization in 33 asymptomatic patients 0.5 to 11 years (mean 4.6) after the Mustard operation for complete transposition of great arteries. Ages had ranged from 16 4.2 years). using videodensitometric determination ejection fraction volume data. Ventricular volumes were obtained by computerized video analysis utilizing Simpson's rule. The right 37 +/- percent (standard deviation), as with videodensitometry 42 10 volume--both values less than normal (P 0.001). end-diastolic significantly greater 0.001) averaged 202 70 percent, but only 125 53 percent. These observations indicate that is seriously decreased relatively preserved function. They support efforts surgical correction ventricle systemic ventricle.
